Description
FIELD OF THE INVENTION
[0001] The present invention is directed to computer display
interfaces and, more particularly, to a method of dynamically
controlling an Internet browser interface and a dynamically
controllable browser interface.
BACKGROUND OF THE INVENTION
[0002] When accessing the Internet (i.e., the worldwide web, the
web, etc.), an Internet user typically executes, via a computer, a
browser software program such as, for example, Netscape
Navigator.TM. or Microsoft Internet Explorer.TM.. The browser
program (i.e., a browser) establishes a physical link to the
Internet (via a modem and an Internet Service Provider (ISP), for
example) and also provides a textual and graphical user interface,
i.e., a browser interface, having a predetermined look and
functionality, neither of which can currently be significantly
changed by the Internet user. Thus, the browser interface remains
relatively static as the Internet user navigates the Internet and
moves from application to application or HTML (Hyper-text Mark-up
Language) page to HTML page.
[0003] Limited control of the browser interface is currently
available via an executable software program that may, for example,
add functional buttons to the interface. However, the additional
functionality is added to the browser interface when the browser is
initially activated and remains static thereafter. Thus, it is not
possible for a browser displaying a browser interface modified as
just-described to dynamically download information from an Internet
site and customize itself, either when the browser is initiated or
as the users traverses the Internet. Such a modified browser
interface also does not provide access to the various browser
Application Programming Interfaces (APIs) for Plug-ins and
interfaces.
[0004] The proliferation of Internet sites makes it increasingly
difficult for content providers (i.e., owners of Internet sites) to
maximize the time an Internet user spends at a particular Internet
site. It is, of course, desirable for a content provider to be able
to maximize that time an Internet user spends at that provider's
Internet site, or to ensure that an Internet user returns to the
content provider's site; this being generally referred to in the
art as stickiness. It is also desirable to maximize the number of
Internet users accessing a content provider's site. Briefly stated,
an Internet content provider wants to attract a maximum number of
Internet users to that provider's Internet site, and to maximize
the amount of time those Internet users remain at that site;
neither of which is possible using current Internet browsers.
SUMMARY OF THE INVENTION
[0005] The present invention is directed to a method of dynamically
controlling an Internet browser interface and to a dynamically
controllable browser interface. The present invention is also
directed to a method of increasing the number of times an Internet
user accesses a predetermined Internet site, and to a method of
increasing the amount of time an Internet user spends at a
predetermined Internet site.
[0006] As used herein, the term controlling and controllable refer
to, by way of non-limiting example, adding to, removing from, and
modifying an Internet browser interface. An Internet browser
interface, as referred to herein, means the visual or aural
presentation presented to a browser user, and via which a user
interacts with the browser. The term customize (and variations
thereof) may also be used herein to describe the controllability
provided in accordance with the present invention. As used herein,
the term dynamically controlling (and variations thereof) refers to
a method by which a part of an Internet browser interface (i.e., an
interface object) may be displayed and periodically changed or
updated while a browser displaying the interface object is
activated.
[0007] A browser, as used herein, is given its general, art
recognized meaning, and generally refers to a software program that
provides an interface to the World Wide Web or Internet. The
browser enables an Internet user to navigate the Internet and
establish a connection to various Internet sites and view the web
page(s) provided at the various Internet sites by content
providers. A browser is specifically capable of calling, i.e.
loading onto the Internet user's computer, an ActiveX control or
Plug-in via an Internet site. The browser also enables an Internet
user to navigate between and among Internet sites, i.e., to surf
the web. The browser provides a browser interface to the Internet
user that is formatted by the provider of the browser software
program. The browser interface typically defines the layout (e.g.,
color, size, number and location) and functionality provided by the
browser to the Internet user. The browser interface may comprise a
first parent window that typically defines the general size, color,
and layout of the browser interface and includes window control
buttons (e.g., minimize, close, etc.). The browser interface may
also comprise a second parent window (a child to the first parent
window), and one or more windows dependent from the second parent
(i.e., children). The second parent and its dependent windows may
provide, for example, various information (e.g., advertisements,
coupons, news, HTML links, etc.) and functionality (i.e., toolbars,
pull-down menus, Plug-ins, applications, etc.) to the Internet
user.
[0008] An ActiveX control, as used herein, refers to a tool for
linking desktop applications for the Internet and is based on art
recognized, Microsoft-developed specifications. A Plug-in, as used
herein, refers to a type of program developed for use with Netscape
browsers and that integrates with a larger application (e.g., a
browser software program) to add a specific functionality or
capability to that larger program. An ActiveX control and a Plug-in
as described above and as referred to herein may be used with any
Internet browser.
[0009] As used herein, the term Internet site refers to a location
(i.e., node) on the Internet defined by an Internet address or URL
(uniform or universal resource locator). As used herein, the term
Internet web page refers to a collection of hypertext markup
language (HTML) commands provided at an Internet site and that
provide formatting information for the text, graphics, and
functionality to create a hypertext document that may be displayed
on an Internet user's computer display via a browser. For example,
an Internet user enters a URL to establish a connection to an
Internet site, and that Internet site provides HTML commands to the
user's browser to enable display of that Internet site's web page
on the user's computer display. The browser interprets hypertext
markup language (HTML) commands embedded in a web page and uses the
HTML commands to format the text and graphics for that web
page.
[0010] The present invention provides advantages to an Internet
user, an Internet content provider (i.e., an owner of an Internet
site), and to an Internet Service Provider (ISP). For an Internet
user, the present invention provides a method of dynamically
controlling or customizing that user's Internet browser interface.
The Internet user may now customize the browser interface so that
each time the user accesses the Internet using a browser,
user-defined information and/or functionality (also collectively
referred to herein as information) will be displayed with the
browser interface. For example, the user may include bookmarks,
address and phone books, personal financial information,
personalized news, and various functionality such as is available
via ActiveX control and Plug-ins.
[0011] In addition, if an Internet user has an account with a
content provider, that user's specific account information (e.g.,
investment portfolio, news headlines, bookmarks, address book,
etc.) may now be dynamically displayed with the browser interface
by the browser. Currently, an Internet user can only access that
user's specific account information while connected to the content
provider's Internet site. The user must return to the content
provider's site to receive updated account information. The account
information is not displayed with the browser interface once user
leaves that Internet site. The present invention provides a method
of dynamically controlling and a dynamically controllable browser
interface that enables an Internet user to display with the browser
interface and continuously update information and/or functionality
specific to that user.
[0012] For a content provider, the present invention ensures that
an Internet user (via a browser) automatically establishes a
connection to that content provider's Internet site every time that
user accesses the Internet using a browser. Thus, as soon as an
Internet user causes a browser to execute (by selecting a browser
icon, for example), the browser automatically establishes a
connection to the content provider's Internet site to load that
user's customized browser interface information. The present
invention may also periodically and automatically cause the user's
browser to connect to the content provider's Internet site while
the browser is active, i.e. while the user surfs the web. In one
embodiment, the content provider may provide an Internet user with
access to a program for controlling the browser interface. Once the
Internet user has accessed that controlling program to customize
that user's browser interface, a connection to that content
provider may be automatically established by that user's browser
every time that user accesses the Internet. Thus, and in contrast
to currently available browsers which establish a connection to an
Internet site only when the user enters a URL (or otherwise
positively acts to cause a connection to be established such as,
for example, by selecting a link or banner advertisement), the
present invention automatically establishes a connection to the
content provider when the browser is initiated, independent of any
home web page selection pre-programmed into the browser, whether by
the Internet user or browser vendor. Once that initial connection
is established, the content provider may load user-specific
information and/or functionality to the Internet user's computer
for display with that user's browser interface.
[0013] In addition, the content provider can also periodically
cause the browser to automatically reconnect to that content
provider's Internet site to update, download new, or otherwise
communicate information and/or functionality for the Internet
user's browser interface. For example, if an Internet user
subscribes to an email service of the content provider, email
messages for that Internet user received by the content provide may
be automatically communicated to the Internet user even though the
user is "surfing" elsewhere. When the user's browser initially
establishes a connection to the content provider's Internet site
upon execution of that user's browser, the information communicated
by the content provider to the Internet user includes instructions
for the browser to periodically reconnect to the content provider's
Internet site. Thus, regardless of the number of Internet sites the
user accesses, and regardless of the particular Internet site
currently accessed by a user, a connection back to the content
provider's Internet site will be automatically established at
intervals determined by the content provider; those reconnections
being transparent to the Internet user except when the user
receives a notification from the content provider (i.e., new mail
has arrived). Thus, the browser interface may be dynamically
controlled as the Internet user surfs the web. For an ISP, the
benefits are at least as great as for a content provider.
[0014] Initially, the browser interface for an Internet user must
be customized using a software program that may be provided by the
content provider or ISP, or that may be available on the user's
computer. The software program, referred to hereinafter as a
controlling program or a program for controlling (and other
variations thereof), changes the manner in which the user's browser
functions. More specifically, the controlling program downloads or
creates a library file on the Internet user's computer. The library
file may be, for example, a Dynamic Link Library (DLL) (for a
Windows operating system) that creates a shell (or plurality of
shells) within the browser and within which various information
and/or functionality may be loaded as an ActiveX control or
Plug-in. The library file includes ActiveX control or Plug-in
functionality that defines an interface object added to the browser
interface in accordance with the present invention. When an
Internet user activates a browser, the library file is opened and
the ActiveX control or Plug-in code contained within that file is
made available to the browser and incorporated into the browser
interface, thus causing the interface object to be displayed with
the browser interface. The library file, and consequently, the
shell (or shells), remain open as long as the browser is activated,
generally as long as the user is surfing the web. Thus, the
information and/or functionality for customizing the browser
interface and loaded in the shell remain active even as the user
moves from Internet site to Internet site. When used in this
context herein, the terms information and functionality refer to
any information, data, and/or software-driven functionality that
can be contained in or part of the library file.
[0015] The library file also causes the browser to establish a
connection to the content provider's Internet site when the browser
is initially activated by the user. The content provider's Internet
site will load information and/or functionality for the interface
object to the user's computer for use in the browser and for
display in the browser interface. The information and/or
functionality loaded by the content provider may be specific to an
Internet user if, for example, that user has an account with the
content provider. Alternatively, the content provider may load
general information and/or functionality if, for example, the
Internet user does not have an account with the content provider
(i.e., is a guest).
[0016] The present invention uses an object linking and embedding
(OLE) in-process server to control the information and/or
functionality of a browser interface. Using an ActiveX control or a
browser Plug-in (each being referred to herein as a browser
interface overlay (BIO) Library) contained in a library file,
virtually any information and/or functionality available with an
ActiveX control or Plug-in may be added to a browser interface
using the present invention. The library file (via the BIO Library)
thus includes the code required to customize, i.e., add, remove
and/or modify, the browser interface.
[0017] Once an Internet user has accessed the controlling program
and customized the operation of that user's browser, the customized
browser interface is displayed when the browser is activated. In
contrast to prior art browser modification methods, the present
invention provides a method and browser interface that may be
dynamically controlled. Updated or changed information and/or
functionality may be communicated to the browser and displayed in
the browser interface as the Internet user surfs the web and while
maintaining the customized information and/or functionality of the
browser interface. Thus, an Internet user may automatically receive
up-to-date information such as, for example, stock quotes, email,
new headlines, at that user's browser interface, at any Internet
site and as long as the user is surfing the web using the
browser.
[0018] Other objects and features of the present invention will

DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS
[0027] The present invention is directed to a method of controlling
and displaying an Internet browser interface, and to a controllable
Internet browser interface. In accordance with the present
invention, a browser interface may be customized using a
controlling software program that may be provided by an Internet
content provider, an ISP, or that may reside on an Internet user's
computer. The controlling software program enables the Internet
user, the content provider, or the ISP to customize and control the
information and/or functionality of a user's browser and browser
interface.
[0028] Referring now to the drawings in detail, FIG. 10 is a block
diagram of a computer 50 connected to the Internet 90 and upon
which the present invention may be implemented. Computer 50
includes an internal bus 64 that facilitates communication of
information (i.e., digital data) between and among the various
devices of the computer 50 and that also facilitates communication
between the computer and external devices and systems via a
communication interface 68. A processor 66 coupled to the bus 64
process information within the computer 50. The computer 50 also
includes a main memory 60 such as, for example, Random Access
Memory (RAM) or other equivalent dynamic memory storage device,
coupled to bus 64 for receiving and storing instructions
communicated from the processor 66. Main memory 60 may also be used
to temporarily store variable or other intermediate information
while the processor 66 executes instructions. Read-Only-Memory
(ROM) 62 is also coupled to the bus 64 for storing static data and
instructions for use by the processor 66. Various input and output
devices are provided as part of the computer 50, including, by way
of non-limiting example, a display 54 (e.g., cathode ray tube
(CRT), liquid crystal display (LCD), etc.), an input device 56 such
as a keyboard, and a cursor control device 58 such as a mouse, or
trackball, for example. A data storage device 52 such as, for
example, a magnetic disk drive and magnetic disk, a CD-ROM drive
and CD-ROM, or other equivalent devices and data storage mediums,
is coupled to the bus 64 for communication with the processor 66,
main memory 60, and communication interface 68. The storage device
52 preferably has an operating system 70 and an Internet browser
software program 72 (i.e., a browser) stored thereon. As will be
discussed in greater detail below, a library file 74 may also be
stored on the data storage device 52.
[0029] The computer 50 may connect to the Internet 90 via the
communication interface 68 over a transmission media including, but
not limited to, coaxial cable, copper wires, and fiber optical
cables. Communication between the computer 50 and the Internet 90
may also be via a wireless or cellular interface. The communication
interface 68 facilitates two-way communication between the computer
50 and another electronic device or system, e.g., a server computer
(not shown) provided by a content provider 100, 200.
[0030] An Internet user (not shown) using the computer 50 may gain
access to the Internet 90 by causing the browser 72 to execute,
thereby opening a communication link between the communication
interface 68 of the computer 50 and an Internet site 130 of a
content provider 100, via an Internet Service Provider (ISP) 80.
The browser 72 provides, to the computer display 54, a browser
interface 20 (see, e.g., FIG. 1) having a layout (e.g., color,
size, number, location) and functionality of windows 30 that is
predetermined in the browser 72 by the browser vendor. Internet
content is communicated by the content provider 100 to the computer
50 for display in a content window 32 of the browser interface
20.
[0031] In accordance with an embodiment of the present invention, a
first Internet content provider 100 may provide an Internet user
with access to a program 120 for controlling the browser 72 and
browser interface 20. When executed by the user, the controlling
program 120 downloads or creates a library file 74 such as, for
example, a Dynamic Link Library (DLL), on the data storage device
52 of the Internet user's computer 50. The library file 74
preferably includes ActiveX control or Plug-in functionality.
Thereafter, when the Internet user accesses the Internet using the
browser 72, the browser 72 opens the library file 74 and preferably
automatically establishes a connection to the content provider's
Internet site 130. The content provider, in response to the
connection established by the browser 72, loads information and/or
functional data into a shell operating within the browser and
created by the library file 74. For example, if the user has an
account with the content provider 100, customized information
and/or functionality may be loaded into the library file 74. If the
user does not have an account, more generalized (i.e., guest)
information and/or functionality may be loaded.
[0032] The library file 74 essentially opens a shell (or a
plurality of shells) within the browser 72 that contains the
ActiveX control or Plug-in code that may control, i.e., add,
remove, and/or modify, the Internet browser 72 and the browser
interface 20. When loaded with the ActiveX control or Plug-in, the
library file 74 preferably contains functions, objects, data, and
other software, referred to generally herein as information, that
may be used to control the browser 74 and browser interface 20. The
present invention ensures that the library file 74 (and shell) does
not close when the Internet user moves from Internet site 130 to
Internet site 230. Thus, the information and/or functionality
provided via the ActiveX control or Plug-in is not lost when the
Internet user disconnects from the Internet site that loaded the
ActiveX control or Plug-in, and connects to another Internet
site.
[0033] Referring next to FIG. 1, a prior art Internet browser
interface 20 having a plurality of windows, each providing various
functionality to the Internet user, is there depicted. The browser
interface 20 may comprise a first parent window 30 that typically
defines the general size, color, and layout of the browser
interface and includes window control buttons 28 (e.g., minimize,
close, etc.) for that window 30. The browser interface 20 may also
comprise a second parent window 36 (a child to the first parent
window) within the first parent window 30, and one or more child
windows 38 dependent from the second parent. The second parent
window 36 and child windows 38 typically define information and/or
functionality that will assist an Internet user when accessing and
navigating the Internet. For example, the second parent 36 and its
dependent windows 38 may provide toolbars, pull-down menus,
Plug-ins, applications, etc.
[0034] For example, three windows 38 provided at the top (in the
drawing) of the interface 20 define three toolbars 22, which may
include a variety of interface controls 24 such as, for example,
pull-down menus, functional buttons (e.g., stop, back, forward,
home, etc.), and a combination of functional buttons and windows
(e.g., a search button and window). The uppermost toolbar 22
provides a plurality of pull-down menus 24; the middle toolbar 22
provides a plurality of functional buttons 24; and the lowermost
toolbar 22 provides a pull-down menu and a window 26 (a URL address
window). A content window 32 is also provided as part of the
interface 20 within which content from an Internet content provider
100 (see, e.g., FIG. 10) may be displayed. The Internet user may
toggle any of the lower three (in the drawing) toolbars 22 on and
off using a View toolbar object 24 (pull-down menu) provided in the
second toolbar 22. However, the Internet user currently may not
add, remove, or otherwise modify the browser interface 20.
[0035] An Internet browser 20 configured in accordance with various
embodiments of the present invention is depicted in FIGS. 2-4. In
FIG. 2, the browser interface 20 includes an interface object 40
that is defined by the ActiveX control or Plug-in loaded in the
library file 74 by the content provider 100. The interface object
40 comprises a pull-down menu 44 and is displayed in the browser
toolbar 22 with the interface controls (i.e., browser toolbar
objects) 24 provided by the browser 72. In FIG. 3, an interface
object 40 comprises an interface object toolbar 42 and a pull-down
menu 44 displayed as a separate window 48 within the browser
interface 20. In FIG. 4, an interface object 40 comprises an
interface toolbar 42 including a plurality of pull-down menus 44
and a search window 46 displayed within a separate 48 within the
browser interface 20. An interface object 40, in accordance with
the various embodiments of the present invention, may comprise
virtually any type of information and/or functionality available
via a browser. Thus, by way of non-limiting example, an interface
object 40 may comprise a pull-down menu, a toolbar and a pull-down
menu, textual information (e.g., advertisements, coupons, etc.),
textual and/or aural information (e.g., a textual advertisement
with accompanying sound), textual, aural, and/or graphical
(animated or not) information, video, video and audio, audio,
etc.
[0036] The various embodiments of the inventive Internet browser
interface 20 depicted by FIGS. 2-4 are merely illustrative,
non-limiting examples of the present invention. Variations to the
depicted browser interfaces 20 may be possible in accordance with
the teachings provided herein.
[0037] Referring next to FIG. 5, a method of controlling an
Internet browser interface 20 is there depicted in accordance with
an embodiment of the present invention, and designated generally as
500. At step 510, an Internet user accesses a controlling program
120 via an Internet web site 130, an ISP 80, or the user's computer
50. The controlling program 120, when executed by an Internet user,
provides that user with the ability to thereafter control that
user's Internet browser interface 20, as discussed in more detail
below. The controlling program 120, at step 520, downloads or
creates a library file 74 on the Internet user's computer 50 that
includes ActiveX control or Plug-in code that define an interface
object. Each time the Internet user activates the browser 72, the
library file 74 is opened and a connection is automatically
established to a predetermined Internet web site 110, one that is
preferably configured to communicate (i.e., download) to the
Internet user's computer 50, ActiveX control or Plug-in code for
the interface object, as indicated at steps 530 and 540. The open
library file 74 essentially provides a shell within the browser 70
within which the functionality provided by the ActiveX control or
Plug-in may be added to the browser interface 20. Neither the
library file 74 nor the shell close until the browser 72 is closed.
At step 550, an interface object 40 is created that will be
displayed in the browser interface 20; the information and/or
functionality of the interface object 40 is defined by the ActiveX
control or Plug-in. In accordance with the various embodiments of
the present invention, the interface object 40 remains displayed by
the browser 72 with the browser interface 20, as indicated at step
560, for as long as the user continues to surf the web, i.e., as
long as the browser 72 is activated. Thus, the functionality added
to the browser 72 and browser interface 20 in accordance with the
present invention is not lost as the Internet user surfs the
web.
[0038] The present invention provides various embodiments for
controlling the browser 72 and browser interface 20, described
generally above with reference to FIG. 5, each of which will now be
described in detail.
[0039] Referring next to FIG. 6 and with continued reference to
FIG. 10, a description of an embodiment of a method of controlling
and displaying a browser 72 and browser interface 20 in accordance
with the present invention, designated generally as 600, will now
be provided. For purposes of FIG. 6 and for the following
discussion directed thereto, a library file 74 has already been
downloaded or created on the Internet user's computer 50, as
discussed herein. At step 610, an Internet user activates a browser
72 to initiate access to the Internet 90. At step 620, the library
file 74 is opened and a connection automatically established to a
predetermined content provider, as indicated at step 630. The
functionality defined by the ActiveX control or Plug-in code of the
BIO Library is communicated by the content provides to the user's
computer 50, (i.e., to the library file 74) to create an interface
object 40 which may be added to the browser interface 20. The
interface object 40 is displayed with the Internet browser
interface 20, as indicated in step 640. The functionality of the
interface object 40, as defined by the ActiveX control or Plug-in
code, remains with the Internet browser interface 20 as the
Internet user traverses the Internet 90, regardless of the number
or type of Internet sites the user visits, and as long as the
browser 72 remains operational, i.e., as long as the Internet user
is accessing the Internet 90 using the browser software program 72.
When the Internet user moves from one Internet site to another, as
indicated at step 650, the present invention determines whether the
interface object 40 has survived that move, i.e., whether it is
still displayed by the browser 72 in the browser interface 20, as
indicated at step 652. If the interface object 40 is not displayed
in the browser interface 20 (i.e., it has been removed from the
browser interface 20 or otherwise terminated), the interface object
40 is redrawn, as indicated in step 660. If the interface object 40
has survived a user move from one Internet site to another and
remains displayed in the browser interface 20, the present
invention also determines, at step 654, if the browser 72 is
active; since the interface object 40 is only displayed in the
browser interface 20 when the browser 72 is operational. If the
browser 72 is not active (i.e., the user is no longer surfing the
web), the interface object 40 is terminated and the library file 74
is closed, as indicated at step 670. If the browser 72 remains
active, the present invention continues, at step 652, to ensure
that the interface object 40 is displayed with the browser
interface 20. As the Internet user moves between and among Internet
sites, the present invention monitors the status of the interface
object 40 and ensures that it is displayed by the browser 72 with
the browser interface 20 as long as the user is traversing the
Internet 90.
[0040] According to the embodiment depicted in FIG. 6, the present
invention ensures that the interface object 40 is displayed by the
browser 72 with the browser interface 20 when the Internet user
leaves the Internet web site 130 at which the BIO Library initially
was called and loaded to the user's computer 50. For example, when
the user activates the browser 72, a connection is automatically
established to a first, predetermined Internet site 130 that is
maintained by a first content provider 100 and the BIO Library is
loaded onto the user's computer 50. The functionality provided by
the BIO Library is then available to the browser 72 via a shell
created by the library file 74. When the Internet user connects to
a second Internet site 230 maintained by a second content provider
200, the functionality for the interface object 40 will continue to
be present in the browser interface 20. In this embodiment, the
present invention prevents the browser 72 or operating system 70 of
the computer 50 from disabling the functionality of the BIO Library
by unloading the library file 74 when the link to the first
Internet site 130 is terminated.
[0041] For example, when the browser 72 initially connects to the
first Internet site 130, that site 130 communicates functional
information in the form of ActiveX control software code to the
Internet user's computer 50 as a BIO Library, which is loaded into
the library file 74. If the library file 74 is not explicitly
instructed by the operating system 70 or the browser 72 to close or
unload when the connection to the first Internet site 130 is
terminated, the library file 74 will remain loaded, providing the
desired functionality for the interface object 40 in the browser
interface 20, even after the connection to the first Internet site
130 is closed. Keeping the library file 74 loaded while the
Internet user moves between and among various Internet sites
enables the loading of data, functions and objects outside of the
ActiveX control (which is only communicated to the Internet user 50
by the first Internet site 130) but inside of the library file 74.
As long as the library file 74 remains loaded, any data or objects
created in the library file 74 and outside of the ActiveX control
will stay loaded and continue to function in the browser interface
20.
[0042] To keep the library file 74 open during surfing, after the
browser 72 has connected to the first Internet site 130, and before
that connection is terminated, a global object, object A, is
created in the program heap of the Internet user's computer 50, not
the calling function heap. Thus, the global object survives the
completion of the calling function. The global object may be
created using the C++ new operator, or by declaring a global object
in the global declarations. In either case, the global object will
survive termination of the connection between the browser 72 and
the first Internet site 130.
[0043] A global object thus defined remains functional after the
ActiveX control provided by the first Internet site 130 closes,
i.e. after the initial connection to the first Internet site 130 is
terminated. Once the global object has been created, an interface
is created using the global object. That interface will serve to,
for example, remove, replace and/or add functionality to the
browser 72 and browser interface 20. The interface may be created
as part of the global object, or by the global object allocating a
new interface object 40. For example, the interface object 40 may
be created by creating, for example, an interface object window 48
within a browser window 38 (see, e.g., FIGS. 3 and 4), and adding
it to the browser interface 20 as a child window Alternatively, the
browser interface 20 may be directly modified such as, for example,
by adding or modifying a browser toolbar 22 or a browser toolbar
object 24 in the browser interface 20. Yet another alternative is
to create an object interface toolbar 42 that is separate from the
browser interface 20, as depicted in FIG. 4.
[0044] Additionally, a pointer is required that is used to control
the browser 72, i.e. to instruct the browser 72 to establish a
connection to a predetermined Internet site 130, for example. That
pointer is preferably stored globally so that it is accessible by
any function or object in the library file 74 that sends commands
to the browser 72. In Microsoft Internet Explorer, for example, the
IWebBrowser, IWebBrowser2, or IWebBrowserApp object linking and
embedding (OLE) interface commands may be used to create the
pointer. Using Microsoft Foundation Class (MFC), for example, the
pointer may be created using the GetClientSite member of the
COleControl class to retrieve a pointer from the first Internet
site 130, i.e., the Internet site which loaded the BIO Library. The
GetClientSite serves as the entry point for the browser 72 to
communicate with the BIO Library. A GetContainer member of the
IOleClientSite class returned by the previous step may be used to
get a pointer to a container for the BIO Library. The BIO Library's
container is a container within which an ActiveX control is loaded.
An Internet browser interface 20 generally consists of several
parts, including the browser toolbars 22 and the content window 32.
A document object is created by the browser 72 for every web page
an Internet user accesses and contains all of the data that appears
in a particular web page. The document object is also the container
for the BIO Library. Thus, a document object may also be referred
to as a BIO Library's container.
[0045] A QueryInterface member of the IOleContainer class returned
by the previous step may be used to get a pointer to the
IServiceProvider interface, which may be used to locate any of the
other interfaces that are presented by the browser 72. Finally, a
QueryService member of the IServiceProvider class returned by the
previous step may be used to get a pointer to the IWebBrowserApp,
IWebBrowser, or IWebBrowser2 interface, depending on the specific
interfaces provided by the browser 72 that called the BIO
Library.
[0046] In an alternative embodiment, the present invention may be
used to modify the entire browser window 30. If the entire browser
window 30 is modified, as opposed to integrating an interface
object 40 into an existing browser window 38, the entire class for
the modified browser window 30 may be subclassed or, alternatively,
the specific browser window 38 may be subclassed. As used herein,
the term subclassing a window, also referred to as hooking a
window, refers to the replacement of an original browser window
message handling procedure for handling all messages sent to a
window, with a user-defined window message handling procedure. For
example, a window may be subclassed using the Microsoft Foundation
Class (MFC) CWnd:SubclassWindow( ) function. Alternatively, a
window may be subclassed using the call the SetWindowLong function
(a Microsoft Windows function), with the GWL_WNDPROC argument (a
Microsoft Windows constant). The pointer returned by the
SetWindowLong function call may be stored to the original browser
window message handling procedure for the subclassed window. This
enables the BIO Library to intercept all messages passed to a
window 30 or 38, and the BIO Library may interpret commands from
interface controls 24 including buttons, menus, etc., provided by
the browser 72 or from interface objects 40 that have been added by
the BIO Library in accordance with the present invention.
[0047] The user-defined window message handling procedure that the
BIO Library provides and that replaces the original browser window
message handling procedure is referred to herein as the BIO
Procedure. Using the BIO Procedure for the browser 72, messages
(i.e., commands) intended for the browser 72 may be intercepted and
modified, or replacement or new messages (e.g., message handlers
for the interface object 40) may be communicated to the browser 72
by the BIO Procedure.
[0048] The present invention also ensures that the interface object
40 has not been removed from the browser interface 20. For example,
some Internet browsers 72 redraw the entire browser interface 20
when an Internet user accesses a new web site. While the global
object may still be functional following such Internet movement by
the user, the interface object 40 will be removed from the browser
interface 20 and thus, will not be displayed with the browser
interface 20. To prevent this from occurring, messages (i.e.,
commands) from the browser 72 to repaint the browser interface 20
may be intercepted by the BIO Procedure and the interface object 40
may be redrawn immediately after the browser interface 20 is
redrawn. Alternatively, the presence of the interface object 40 in
the browser interface 20 may be periodically tested and if not
present in the browser interface 20, the interface object 40 may be
redrawn. Such periodic testing should preferably occur at intervals
of less than approximately one second.
[0049] As an example of the above-described embodiment (depicted in
FIG. 6), an ActiveX control is loaded as a BIO Library and adds
menu items (and functionality) to the browser interface 20. The
present invention creates an ActiveX control that dynamically
creates a new global object, object A, which creates a new menu
object (i.e., an interface object 40) with a desired functionality
to be added to the browser interface 20. The menu object 40 may be
added to the browser interface 20 using, for example, the
instructions: AfxGetMainWnd( ).fwdarw.GetMenu( ).fwdarw.AppendMenu(
), where the appended menu of the browser interface 20 would
include a popup menu that points to the menu object 40. The browser
interface window would then be subclassed and handle the messages
for the menu object 40 handled by the BIO Procedure and the
messages for the browser interface 20 being passed to the message
handler for the browser 72. When the Internet user disconnects from
the first Internet site 130 (i.e., leaves the web page containing
the ActiveX control), the ActiveX control will close, but the
global object, i.e., object A, will remain in the program heap and
continue to provide the desired functionality to the browser
interface 20.
[0050] Instead of subclassing the browser window within which the
interface object 40 is added, object A, or one of its descendents,
may retain ownership of the interface object 40. Then, a message
handler for the interface object 40 may be created. For example, an
interface object 40 may be added to a browser toolbar 22 in
accordance with the above-described embodiment of the present
invention, except that ownership of the interface object 40 is set
using the Microsoft Foundation Class SetOwner function to be object
A or one of it's descendents.
[0051] With reference next to FIG. 7 and continued reference to
FIG. 10, a description of an alternate embodiment of a method of
controlling and displaying a browser interface 20 in accordance
with the present invention, designated generally as 700, will now
be provided. For purposes of FIG. 7 and for the following
discussion directed thereto, a library file 74 has already been
created on the Internet user's computer 50, as described herein. At
step 710, an Internet user activates a browser 72 to access the
Internet 90. At step 720, the library file 74 is opened on the
user's computer 50, and a connection is automatically established
to a predetermined Internet site 130, as indicated at step 730. At
step 740, the functionality defined by the ActiveX control or
Plug-in code of the BIO Library is communicated by the content
provider to the user's computer 50 (i.e., to the library file 74)
to create an interface object 40 which may be displayed in the
browser interface 20 using a continuous loop to control the display
of the interface object 40. The interface object 40 may only be
removed (i.e., its functionality terminated) upon termination of
the continuous loop. The functionality of the interface object 40,
as defined by the ActiveX control or Plug-in code, remains with the
Internet browser interface 20 as the Internet user traverses the
Internet 90, regardless of the number or type of Internet web sites
the user visits, and as long as the browser 72 remains operational,
i.e., as long as the Internet user is accessing the Internet using
that browser software program. When the Internet user moves from
one web site to another, as indicated at step 750, the present
invention determines whether the interface object 40 has survived
that move, i.e., whether it is still displayed in the browser
interface 20, as indicated at step 752. If the interface object 40
is not displayed by the browser 72 in the browser interface 20
(i.e., it has been removed from the browser interface 20 or
otherwise terminated), the interface object 40 is redrawn, as
indicated in step 760. If the interface object 40 has survived a
user move from one web site to another and remains displayed in the
browser interface 20, the present invention also determines, at
step 754, if the browser 72 is active; since the interface object
40 is only displayed by the browser 72 in the browser interface 20
when the browser 72 is operational. If the browser 72 is not active
(i.e., the user is no longer surfing the web), the interface object
40 is terminated and the library file 74 is closed, as indicated at
step 770. If the browser 72 remains active, the present invention
determined, at step 756, whether the continuous loop has been
terminated. If the loop has been terminated, the interface object
40 is also terminated, as indicated at step 770. If the loop is
still executing, the present invention determines whether the
interface object 40 is still displayed in the browser interface 20,
as indicated at step 752.
[0052] The embodiment of the present invention depicted in FIG. 7
prevents an ActiveX control from unloading by freezing the
operation of the library file 74 (within which the ActiveX control
code is loaded), even if the operating system 70 or browser 72
generate an instruction to unload or terminate the library file 74.
Because the library file 74 is frozen and never finishes unloading,
all of the data, functions and objects created inside of the
library file 74 by the ActiveX control will continue to exist and
function after the library file 74 has been instructed to
unload.
[0053] In some operating systems 70 and/or browsers 72, the BIO
Library will be closed when the ActiveX control is no longer
present at an Internet site. This can also occur when the Internet
user moves from an Internet site having the ActiveX control, e.g.,
Internet site 130 in FIG. 10, to another Internet site that does
not, e.g., Internet site 230 in FIG. 10. To enable the interface
object 40 to continue to operate in the absence of the ActiveX
control, the BIO Library (and the library file 74) must be
prevented from closing.
[0054] To accomplish this, a pointer is created that is used to
control the browser 72. That pointer is preferably stored globally
so that it is accessible by any function or object in the library
file 74 that may need to send commands to the browser 72. In
Microsoft Internet Explorer, for example, the IWebBrowser,
IWebBrowser2, or IWebBrowserApp OLE Interface commands may be used
to create the pointer. To do this using Microsoft Foundation Class,
the GetClientSite member of the COleControl class (which may be
used to communicate with the BIO Library) may be used to retrieve a
pointer to the BIO Library's Internet site, i.e. that Internet site
that provides the ActiveX control. A GetContainer member of the
IOleClientSite class returned by the previous step may be used to
get a pointer to the BIO Library's container. A QueryInterface
member of the IOleContainer class returned by the previous step may
be used to get a pointer to the IServiceProvider interface. The
IServiceProvider interface is used to easily find any of the other
interfaces that are presented by the browser 72. A QueryService
member of the IServiceProvider class returned by the previous step
may be used to get a pointer to the IWebBrowserApp, IWebBrowser, or
IWebBrowser2 interface depending on the interfaces presented by the
version of the browser 72 that called the BIO Library.
[0055] To prevent the library file 74 from closing, its operation
is halted before it is able to terminate. To freeze or halt the
operation of the library file 74, a continuous program loop may be
created and executed that terminates only when the BIO Library is
to be unloaded, at which time, the program loop also pumps the
message que. The program loop is referred to herein as a message
pump, and may be created using for example, the PeekMessage,
GetMessage, TranslateMessage and DispatchMessage commands in a
loop. Exemplary C++ code to carry out the message pump is provided
below: TABLE-US-00001 while (m_Continue) { if (PeekMessage
(&msg, NULL, 0, 0, PM_NOREMOVE) != 0) { GetMessage( &msg,
NULL, 0, 0 ); TranslateMessage( &msg ); DispatchMessage(
&msg ); } }
where m_Continue is a Boolean variable that is used to instruct the
loop when to stop, and PeekMessage, GetMessage, TranslateMessage,
and DispatchMessage are all Windows functions. If m_Continue equals
false, the loop will end, thus ending the message pump. The msg
argument is a reference to a Windows MSG structure.
[0056] The way the message pump preferably operates is that it
checks to see if there are any messages waiting in the message que
using the PeekMessage function. If there is a message, the message
pump grabs the message from the message que using the GetMessage
function and translates it from a virtual-key message into a
character message using the TranslateMessage function. Finally, the
message pump sends the message to the original window message
handling procedure that is due to receive the message using the
DispatchMessage function.
[0057] The built in capabilities of an operating system 70 may be
also used to construct a message pump to pump the message que. For
example, a modal dialog box or message box, using a command such as
the MFC command CWnd::MessageBox("my modal", MB_OK), serves this
purpose well and may be used to provided the desired freezing or
halting of the operation of the library file 74.
[0058] As long as the message pump is executing a continuous loop,
the ActiveX control will not terminate, even when the Internet user
accesses (i.e., visits) other Internet sites.
[0059] The embodiment of the present invention depicted by FIG. 7
performs in the same manner (e.g., subclassing, message handling,
etc.) as the above-described embodiment of FIG. 6.
[0060] For both of the above-described embodiments (of FIGS. 6 and
7), it is preferable, although not necessary, to provide an exit
function for the interface object 40 so that object A and all of
its descendents will be closed. Possible exemplary scenarios for
calling an exit function include intercepting the message to close
the browser window in the BIO Procedure, or periodically looking
for the browser window and, if it is not found, terminating the
ActiveX control.
[0061] Referring next to FIG. 8A, yet another embodiment of the
method of the present invention is depicted and designated
generally as 800. For purposes of FIG. 8A and for the following
discussion directed thereto, a library file 74 has already been
created on the Internet user's computer 50, as described herein. At
step 810, an Internet user activates a browser 72 to access the
Internet 90. At step 820, the library file 74 is opened on the
user's computer 50 and a connection is automatically established to
a predetermined Internet site 130 (see, e.g., FIG. 10), as
indicated at step 830. At step 832, a new browser interface is
created that is a duplicate of the initial browser interface
provided by the browser 72. At step 840, a Function Window is
created that represents the original browser interface within which
the functionality of the Plug-in was initially loaded.
[0062] The steps for creating a Function Window in accordance with
this embodiment of the present invention are depicted in FIG. 8B
and designated generally as 840. At step 842, the handle for the
initial browser interface window is identified. The initial browser
interface window, now the Function Window, is hidden and/or
disabled at step 844 so that it cannot be closed, which would cause
the BIO Library to crash. At step 846, a pointer is created that is
used to control the browser 72. Finally, a new browser interface
window is created at step 848 that may be used by the Internet user
to continue traversing the Internet.
[0063] With reference again to FIG. 8A, and beginning at step 850,
the browser interface may now be controlled by first subclassing
any browser windows, or any windows used by the browser, that are
to be controlled, and then adding, deleting, and/or modifying the
window(s) as described in more detail below. The original browser
window message handling procedure is replaced with a BIO Procedure
(as defined above). At step 860, the present invention determines
whether any new browser windows have been opened, i.e., windows
that may not already be subclassed or that may not have been
controlled in accordance with the present invention. If new windows
have been opened, the present invention determines, at step 870,
whether the interface object 40 is to be added to those new
windows. If not, the invention determines whether the Internet user
desires to close the browser 72, as indicated at step 880. If so,
the invention closes, at step 890, all browser windows, including
the Function Window. If the user does not desire to close the
browser 72, as determined at step 880, the invention returns to
step 860 and again determines if new browser windows have been
opened.
[0064] With continued reference to FIGS. 8A, 8B and 10, the
above-described embodiment of the present invention will now be
discussed in more detail. When an ActiveX control is loaded by a
content provider 100 via an Internet site 130, typically in
response to a browser 72 establishing a connection to that web site
130 and calling an ActiveX control, a library file 74 located on
the user's computer is caused to open creating a shell within the
browser 72 within which the code for the ActiveX control may be
loaded. If the library file 74 that contains the ActiveX control is
explicitly instructed, by the operating system 70 or the browser
72, to unload (i.e., close) when the ActiveX control is closed
(when the user terminates the connection to the Internet site 130),
any data, functions or objects that have been created outside of
the ActiveX control but in the library file 74 will be destroyed
when the library file is 74 unloaded. To prevent the library file
74 from unloading, the browser 72 is prevented from closing the
ActiveX control until instructed. If the ActiveX control is never
instructed to close, the library file 74 is never unloaded.
[0065] A preferred method of accomplishing this is to hide and/or
disable the initial browser interface window that loaded the
ActiveX control and to create a new copy of that same window within
which the Internet user may continue to work and traverse the
Internet. Because the initial browser interface is preferably
hidden and/or disabled, the ActiveX control cannot be closed until
the library file 74 shows, enables or closes the initial browser
interface window, i.e. the window that loaded the library file
74.
[0066] The above-described method of FIG. 8A preferably loads the
BIO Library as a standard ActiveX control in a browser 74, using,
for example, the <Object> tag typically contained in a web
page 130 or as a Band Object, and as described in the Microsoft
Internet Explorer 4.x Software Development Kit. This instructs the
browser 72 to initialize and run the library file 74 that contains
the code for BIO Library.
[0067] The first time the BIO Library is initialized and called, a
Function Window is created that keeps the BIO Library open by
keeping a session with the ActiveX control itself open while the
Internet user visits other Internet web sites 210, i.e., other web
pages. The Function Window also makes it possible for browser
windows that do not have a copy of the BIO Library open to access
the OLE interfaces to the browser 72.
[0068] To create the Function Window, the initial browser interface
window (i.e., that window which loaded the BIO Library) is
preferably hidden and/or disabled. This may be accomplished by
identifying the handle of the initial browser interface window,
beginning with the handle of the BIO Library. To retrieve the
initial browser interface window handle from the handle of the BIO
Library, the GetParent function (a Windows Function) is
continuously called until the present value for that function call
represents one level below the desktop window. For example, a
statement such as "m_Handle=GetParent(m_Handle)" executed in a loop
may provide the desired functionality and result, where the value
of m_Handle is initially equal to the value for the handle of the
BIO Library, and will eventually return the handle to the initial
browser interface window.
[0069] The next step is to hide and/or disable the initial browser
interface window, now referred to as the Function Window, so that
the Internet user cannot close the Function Window (by closing the
browser 72, for example), thereby causing the BIO Library to unload
and removing the functionality provided by the BIO Library from the
browser interface 20. To hide the initial browser interface window
from the user and/or disable that browser window from user-driven
events, WM_SHOWWINDOW and/or WM_ENABLE messages (both Windows
constants) may be sent to the initial browser interface window with
values to hide and/or disable the browser window. For example, the
PostMessage or SendMessage function (existing Windows functions)
may be used to send a message to the initial browser interface
window with the browser window handle. Alternatively, the
ShowWindow and EnableWindow functions (existing Windows functions)
may be used to achieve the same result.
[0070] A pointer is created to control the browser 72. This pointer
is preferably stored globally so that it is accessible by any
function or object in the library file 74 that sends commands to
the browser 72. In Microsoft Internet Explorer for example, the
IWebBrowser, IWebBrowser2, or IWebBrowserApp OLE interface may be
used to create the pointer. To do this using Microsoft Foundation
Class for example, the GetClientSite member of the COlecontrol
class that serves as the entry point for the browser 72 may be used
to communicate with the BIO Library, and to retrieve a pointer to
the BIO Library's Internet site, i.e., that Internet site 130 that
loaded the ActiveX control. A GetContainer member of the
IOleClientSite class returned by the previous step may be used to
get a pointer to the BIO Library's container. A QueryInterface
member of the IOleContainer class returned by the previous step may
be used to get a pointer to the IServiceProvider interface; with
the IServiceProvider interface preferably being used to find any of
the other interfaces that are presented by the browser 72. A
QueryService member of the IServiceProvider class by in the
previous step may be used to get a pointer to the IWebBrowserApp,
IWebBrowser, or IWebBrowser2 interface depending on the interfaces
presented by the version of the browser 72 that called the BIO
Library.
[0071] Finally, a new browser window is created that the Internet
user may use to continue surfing the web, i.e., to continue
accessing various different Internet sites, since the browser
window previously used to create the Function Window has been
hidden and/or disabled. Preferably, any of the IWebBrowser,
IWebBrowser2, or IWebBrowserApp OLE interface is used to create a
new browser window, for example, using the Navigate or Navigate2
members of that OLE interface. Alternatively, a WM_COMMAND message
that corresponds to any command the browser 72 might use to open a
new browser window such as a New Window command or Open In New
Window command, etc., may be sent to the browser 72. A new window
may also be opened using the Dynamic Data Exchange (DDE) support
provided by the browser 72.
[0072] The BIO Library must now add/delete/modify, i.e., control,
various browser interface features and functionality. The first
step is to subclass any of the browser windows or any of the
windows the browser uses (i.e., children) that are to be controlled
in accordance with the present invention. A BIO window message
handling procedure is used to replace the original window message
handling procedure, and is hereinafter referred to as the BIO
Procedure.
[0073] Once the browser window, or any of it's children, have been
subclassed, it is possible to add menus to a subclass by retrieving
a pointer to the browser window menu using the GetMenu function.
Once the pointer to the menu's handle is obtained, the menu
functions such as ModifyMenu, AppendMenu, InsertMenu, etc., may be
used to add any desired menus to the browser window. Any commands
assigned to a menu must be handled by the BIO Procedure used to
subclass the BIO window. The same command identifier must not be
used in creating a menu as any that are included in the
browser.
[0074] An interface object toolbar 42 may be added to the browser
interface 20 by retrieving the handle of the window to which the
toolbar 42 is to be added to (hereinafter referred to as the Frame
Handle) using standard Windows functions. Typically, the window
will be the BIO window or a frame window that is a child of the BIO
window. A window is then created using the Frame Handle as its
parent. For example, to add a dialog bar (which is a form of a
toolbar) as an interface object 40, an object derived from or of a
type CDialogBar (a Microsoft Foundation Class) is created and it's
Create method called using Frame Handle. If resources such as, for
example, images, toolbars, dialogs, etc., are being used and the
browser 72 does not share the same resources as the BIO Library,
the browser's resources are temporarily replaced with the BIO
Library resources before any data may be loaded from the BIO
Library resource. The BIO Library resources may then be replaced
with the browser's original resources.
[0075] As new browser windows are opened, it may be desirable to
add interface object(s) 40 to those new windows. A timer may be
created using SetTimer Windows function that would call a
user-defined function and that function would use the FindWindowEx
function (a Windows function) to check every child of the desktop
window for a window with the same class name as the Function
Window. For those browser windows that have not already been
modified, i.e., that do not have the interface object 40, the
necessary handles may be retrieved and the same changes made as
were made for the original BIO Window.
[0076] Finally, when the Internet user desires to close the browser
72, it must be determined if all of the browser windows are closed,
except the Function Window, and the Function Window must also be
closed if all other browser windows are closed. This may be
accomplished by listening for a WM_CLOSE message (a Windows
constant) in the BIO message handling procedure or by setting a
timer that periodically determines how many browser windows are
open. To close the original Function Window, a WM_CLOSE message may
be sent to that window.
[0077] Referring next to FIG. 9, another alternative embodiment of
a method of controlling and displaying an Internet browser
interface 20 in accordance with the present invention is depicted
and generally designated as 900.
[0078] Steps 910, 920, and 930 are essentially the same as
described above for the embodiments of FIGS. 6-8. At step 940, a
new browser interface window is created and the initial browser
interface window is hidden and/or disabled, and referred to as a
Function Window. The Plug-in identifies the handle for the initial
browser interface window, hides and/or disables that window, and
creates a new browser interface window that may be used by the
Internet user. At step 950, all the browser windows are subclassed,
and then the browser interface may be controlled, as indicated at
step 960, for all open windows. At step 962, the present invention
determines if any new browser windows have been opened, in which
case the invention returns to step 960. In no new browser interface
windows have been opened, step 962 proceeds to step 964 to
determine if the Internet user desires to close the browser. All
windows must be closed prior to closing the Function Window, and
that is determined at step 966. If all windows are closed, the
Function Window is closed, as indicated at step 970. Otherwise,
step 966 returns to step 964.
[0079] In yet another alternative embodiment of the present
invention, the present invention provides a method of controlling
an Internet browser interface using a browser Plug-in to control
(i.e., add, remove and/or modify) the functionality of the calling
browser 72 and to retain the Plug-in functionality after the user
leaves the Internet site 130 that loaded the Plug-in.
[0080] When a browser Plug-in is loaded to an Internet user's
computer 50 in response to a browser 72 establishing a connection
to an Internet site 130 and calling the Plug-in, a library file 74
establishes a shell within the browser 72 and within which the code
for the Plug-in may be loaded. If the library file 74 is explicitly
instructed by the operating system 70 or the browser 72 to unload
when the Plug-in is closed, any data, functions or objects that
have been created outside of the Plug-in but in the library file
74, will be destroyed when the library file 74 is unloaded. To
prevent the library file 74 from unloading, the browser 72 is
prevented from closing the Plug-in until the browser 72 receives an
instruction to close the Plug-in. If the Plug-in is never
instructed to close, the library file 74 also is never instructed
to unload. This may be accomplished by hiding and/or disabling the
initial browser window that loaded the Plug-in and by creating a
new copy of that same window for the Internet user to continue to
use to access and traverse the Internet. Because the initial
browser window is preferably hidden and/or disabled, the Plug-in
can not be closed until the library file 74 chooses to show, enable
or close the initial browser window that loaded the Plug-in.
[0081] For example, a browser Plug-in is loaded as a standard
Plug-in in a browser 72, preferably by using the <Embed> tag
in a web page 110 (see e.g., FIG. 10), which instructs the browser
72 to initialize and load the library file 74 that contains the
code for the Plug-in (i.e., the BIO Library).
[0082] The first time the BIO Library is initialized and called, a
Function Window is created by hiding and/or disabling the original
browser window, thus preventing the BIO Library from unloading by
keeping a session with the Plug-in itself open. The Function Window
also makes it possible for browser windows that do not have a copy
of the BIO Library open to access built-in Application Programming
Interfaces (APIs) for Plug-ins (i.e., functionality made available
to the Internet user through the browser interface 20 and via the
Plug-in functionality), such as those provided with Netscape
Navigator and Microsoft Internet Explorer.
[0083] A Function Window is preferably created by disabling or
hiding the initial browser window (in which the Plug-in resides)
the first time the Plug-in is called by the browser 72. To do this
the Plug-in must first identify the handle of the initial browser
window. A window member of the NPWindow structure is passed to the
BIO Library from the browser 72 as a second argument to the
NPP_SetWindow Function and is the handle to the Plug-in window
(NPWindow and NPP_SetWindow are part of the Netscape and Internet
Explorer API for Plug-Ins). To retrieve the initial browser window
handle from this window member, the GetParent function (a Windows
function) is continuously called until the present value for that
function call represents one level below the desktop window. For
example, a statement such as "m_Handle=GetParent(m_Handle)"
executed in a loop may provide the desired functionality and
result, where the value of m_Handle is initially equal to the value
for the handle of the NPWindow structure, and will eventually
return the handle for the initial browser window.
[0084] The initial browser window is then hidden and/or disabled so
that the Internet user cannot close the Function Window and cause
the BIO Library to crash. To hide the initial browser window from
the user and/or disable that window from user-driven events,
WM_SHOWWINDOW and/or WM_ENABLE messages (both Windows constants)
may be sent to the initial browser window with values to hide
and/or disable that browser window. This can be accomplished by,
for example, using the PostMessage or SendMessage function (Windows
functions) to send a message to the initial browser window using
the browser window handle. Alternatively, the ShowWindow and
EnableWindow functions (Windows functions) may be used to achieve
the same results.
[0085] The final step is to create a new browser window that the
Internet user can use to continue surfing the web after the initial
browser window has been hidden and/or disabled. This may be
accomplished, for example, by calling any of the following Netscape
and Internet Explorer Plug-in API functions: NPN_GetURL,
NPN_PostURL, NPN_GetURLNotify, NPN_PostURLNotify, with the target
parameter set to _new, _blank, or any window name that does not
already exist. The NPP argument of the above functions is the NPP
structure that was provided by the browser 72 to the Plug-in for
the Function Window. Another way of doing this is to send a
WM_COMMAND message to the browser 72 that corresponds to any
command the browser 72 might use to open a new window such as a New
Window command or Open In New Window command, for example. A new
window may also be opened using the Dynamic Data Exchange (DDE)
Support provided by the browser. NPN_GetURL, NPN_PostURL,
NPN_GetURLNotify, NPN_PostURLNotify and the NPP structure are part
of the Netscape and Internet Explorer API for Plug-Ins and the
WM_COMMAND is a Windows constant.
[0086] The BIO Plug-in may now control, i.e., add/delete/modify,
features and functionality of the browser 72. The first step is to
subclass any of the browser windows or any of the windows the
browser uses (collectively, BIO windows) that are to be controlled
in accordance with the present invention.
[0087] After the browser window or any of it's children has been
subclassed, menus may be added to the browser interface 20 by
retrieving a pointer to the browser window menu using the GetMenu
function (a Windows function). Once the pointer to the menu's
handle is obtained, the menu functions such as ModifyMenu,
AppendMenu, InsertMenu, etc. (Windows functions), may be used to
add any desired menus to the browser window. Any commands assigned
to a menu must be handled by the BIO message handling procedure
used to subclass the BIO window, taking care not to use the same
command identifier in creating a menu as any included in the
browser 72.
[0088] Alternatively or additionally, an interface object toolbar
42 may be added to the browser interface 20 by retrieving the
handle of the window to which the toolbar 42 is to be added
(hereinafter referred to as the Frame Handle) using standard
windows functions--typically the window will be the BIO window or a
frame window that is a child of the BIO window. A window is then
created using the Frame Handle as its parent. For example, to add a
dialog bar (which is a form of a toolbar) as an interface object
40, an object derived from or of type CDialogBar (a Microsoft
Foundation Class) may be created and it's Create method called
using the Frame Handle. If resources such as, for example, images,
toolbars, dialogs, etc., are being used and the browser 72 does not
share the same resources as the BIO Library, the browser's
resources are temporarily replaced with the BIO Library resources
before any data from the BIO Library resource may be loaded. The
BIO Library resources may then be replaced with the browser's
original resources.
[0089] As new browser windows are opened, the interface object 40
may be added to those new windows. This may be accomplished by
creating a timer using SetTimer (a Windows function) that would
call a user-defined function that would use the FindWindowEx
function (a Windows function) to check every child of the desktop
window for a window with the same class name as the Function
Window. For those new windows that do not already have the modified
interface, i.e., that do not include the interface object 40, the
necessary handles are retrieved and the same changes made to those
windows as were made to the original BIO window.
[0090] Finally, when the Internet user wishes to close the browser
72, it must be determined if all of the browser windows are closed
except the Function Window, and if they are, the Function Window
may be closed. This may be accomplished, for example, by listening
for a WM_CLOSE message (a Windows constant) in the BIO window
message handling procedure or by setting a timer that periodically
checks the number of open browser windows. The original Function
Window may be closed by sending it a WM_CLOSE message.
[0091] In accordance with the present invention, a BIO Library
(i.e., a Plug-in) may be loaded and its functionality provided in
the browser interface 20, automatically, i.e., without requiring
the user to positively access a particular Internet site, i.e., to
surf to a web page that calls the Plug-in. For example, Netscape
has a key in its windows registry identified as Automation Startup.
Upon activation, Netscape loads all of the OLE controls that are
listed in the Automation Startup key. By placing a reference or a
call to the library file 74 (and thus to BIO Library and Plug-in
that defines an interface object 40) in the Automation Startup key,
the library file may be loaded every time a user activates a
Netscape browser. Included in that library file 74 may be
instructions to create an instance of the interface object 40 in
the browser interface 20 and an instruction for the browser 72 to
establish a connection to a predetermined Internet site 130. Using
this technique, a user does not have to choose to visit a specific
Internet site 130 to load a BIO Library. The library file 74 needs
to be kept open at least until the Plug-in may be loaded in the
browser 72 for display and access via the browser interface 20. One
way to do this is to increment a reference counter associated with
the library file 74 so that when Netscape unload the OLE controls
listed in the Automation Startup key, the library file 74 will not
be unloaded because it has a higher reference number.
[0092] The library file 74 may be loaded as a Plug-in using DDE to
periodically look for a Netscape DDE Server using a timer or a
loop. When a return is received by the browser 72 from the Netscape
DDE server, Netscape is ready to receive commands and may be loaded
with the Plug-in. DDE may then be used to send a command, such as
WWW_OPENURL, to the browser 72, which will cause the Plug-in to
load as discussed herein.
[0093] Another method for hiding the Netscape Plug-in window that
is used for BIO Library is to remove it from the task bar (i.e.,
where the Windows "Start" button is located) and place it off of
the visible screen. One way to remove it from the Task Bar is to
call SetWindowLong and change the window style of the Plug-in
window to a toolbox window. Toolbox window's do not appear in the
task bar. The Netscape Plug-in window may be placed off screen by
calling MoveWindow and providing coordinates that are not in the
visible range for the users desktop.
[0094] The BIO window message handling procedure that is used to
replace the original browser message handling procedure must know
which window a message is intended to reach and what to do with a
message once the BIO window message handling procedure receives
that message. A preferred way to do this is to create a map that
links one piece of information to another. For the present
invention, a map that links window handles to structures that
contain important information to that window is preferably used.
For example when the BIO Library adds the interface object 40 to a
new browser window, a new entry in the map is created that links
the BIO window's handle to a structure that contains information
useful for that BIO window. One of the pieces of information
contained in the structure would preferably be the browser's
original window message handling procedure for the BIO window. It
is necessary to maintain the browser's original window message
handling procedure so that if the BIO window message handling
procedure does not know how to handle a message, it can pass the
message to the browser's original window message handling
procedure.
[0095] When a message is received by the BIO window message
handling procedure, the first argument that is passed to the
procedure is the handle of the window that received the message. To
retrieve the structure that contains all of the data specific to
that window, a lookup in the map is performed using the window
handle as a key. The returned structure will contain all of the
stored window specific information, such as the original window
message handling procedure.
[0096] When controlling the browser interface 20, i.e., adding to,
removing from or modifying the browser interface, the present
invention changes how the browser 72 works. Almost anything an
Internet user can do with a browser works by sending a message to a
browser's window or child window. Objects or windows that send
messages include the menus, buttons, combo boxes and almost
anything else with which the Internet user can directly interact,
i.e., interface controls. Messages for example can be broken up
into four components: 1) the handle of the window intended to
receive the message; 2) the msg value of the message; 3) a wParam,
whose use is usually dependent on the msg value; and 4) an IParam,
whose value is also usually dependent on the value of the msg
value.
[0097] For example, clicking on a button in a browser's window
might send a message that contains the WM_COMMAND, which is a
Windows constant, msg value to a browser window's window message
handling procedure. The lower two bytes of the wParam variable in
that message would then be a number that is used to identify which
button was pressed.
[0098] By subclassing a browser's window or child window, as
described above, any messages that are sent when a user interacts
with any of the interface controls may be intercepted. Once a
message is intercepted, the BIO window message handling procedure
can interpret it and react to it. If the functionality of the
interface control is to remain the same (i.e., not added to,
deleted from, or modified by the present invention), the message
may be passed back to the original window message handling
procedure. In this way, virtually all of the interface controls
that exist in the browser 72 may be controlled. In addition,
interface controls may be added to the browser interface 20 and
assigned command identifiers (which are passed in the wParam). The
BIO window message handling procedure can then interpret the wParam
and provide the functionality of the Interface control that is to
be added. In addition, functionality may be removed by simply
having the inventive window procedure do nothing if it receives a
command identifier associated with an interface control that is to
be removed from the browser. That command may thus be prevented
from passing to the browser window's original message handling
procedure.
[0099] Using the various embodiment of the present invention, as
discussed in detail above, an Internet user may create a browser
interface 20 having user-defined interface controls. Then, by
setting the parent of the window for that browser interface 20 to a
window that has been subclassed, any message from the new (i.e.,
controlled) window will be handled in the BIO window message
handling procedure. This can be used to add any interface object 40
such as a toolbar, dialogbar, floating dialog etc., to the browser
interface 20.
[0100] The following illustrative, non-limiting application
examples are provided to further describe the present invention. A
Plug-in or ActiveX control that stays persistent as an Internet
user traverses the Internet may add an interface object 40 to the
browser interface 20 that enables a user to download their
"bookmarks" or "favorites" from a database located on the Internet.
The interface will be added directly into the browser interface and
will allow the user to visit the "bookmarks" or "favorites" links
that they downloaded, using the interface object 40 provided by the
Plug-in or ActiveX control. This interface object 40 will serve a
similar function to the current "favorites" or "bookmarks" menu
items and toolbars on existing browsers. The beneficial difference
is that since the bookmarks will be downloaded from a database on
the Internet, users have access to their bookmarks on any
computer's browser that is capable of loading the Plug-in or
ActiveX control.
[0101] The present invention may also be used to generate revenue
based on placing advertising "links" included in the "favorites" or
"bookmarks" on the browser interface 20 via the Plug-in or ActiveX
control. Consumer targeting could be based on, for example,
information stored in databases, such as name, age, sex, income,
race, education and geographic location, and preferences such as
favorites and bookmarks or other preferences that are stored on the
database or exist on the browser 72.
[0102] A Plug-in or ActiveX control that stays persistent as the
user traverses the Internet may be used to add an interface object
40 to the browser interface 20 that permits a user to download
their "address book" from of a database located on the Internet.
Such an interface object 40 may be added directly into the
interface of the browser interface 20 and will allow the user to
send e-mail as well as retrieve stored information for contacts
listed in their "address book".
[0103] The present invention may also be used to earn revenue based
on placing advertising "links" included in the "address book" on an
interface object 40 of the Plug-in or ActiveX control. Consumer
targeting could be based for example on information stored in
databases, such as name, age, sex, income, race, education and
geographic location, and preferences such as favorites and
bookmarks or other preferences that are stored on the database or
exist on the browser.
[0104] The present invention may use a Plug-in or ActiveX control
to add an edit box on the browser interface 20 that allows a user
to type a search directly into the browser instead of having to
visit a web page that allows the user to search.
[0105] Additionally, the Plug-in or ActiveX control that stays
persistent may poll, or periodically seek--at user, web site or
program selected intervals--information from a preferred web site,
even though the user is surfing a different web site. As the
preferred web site is polled, the preferred web site can send
updated information to the interface object on the user's browser,
such as near real-time notification of the receipt of mail,
continuous updating of stock prices, or other time sensitive
information, such as, for example, news feed headlines, sports
scores for selected favorite sports teams, and the like. The
preferred web site can control, if desired, the timing of the
polling, so as to control the traffic at the preferred web site
during peak usage periods by extending the time interval between
polls.
[0106] Since the shell created by the library file, as described
herein, is an environment within which applications can be run, or
information displayed, any information or program can be added to
the interface of the browser using the present invention. The shell
is independent of the browser interface, the content of the
browser, and even the content of the shell itself. In short, the
shell is an adaptable piece of functionality that does not, in the
extreme, even need to be visible to the user. Thus, in use, the
shell can be empty and receive its contents from a web site, or the
shell could get Plug-ins, or the shell could even get new library
files and learn to parse new information "on the fly" as the shell
receives new contents from a web site or user. Thus the present
invention provides significant opportunities to direct desired
information from a preferred site to the user even as the user
visits other sites. Of course, the more user-specific functionality
provided by a web site via the customizable interface of the
present invention, the greater user loyalty that web site can
engender.
[0107] Thus, while there have been shown and described and pointed
out fundamental novel features of the invention as applied to
preferred embodiments thereof, it will be understood that various
omissions and substitutions and changes in the form and details of
the disclosed invention may be made by those skilled in the art
without departing from the spirit of the invention. It is the
intention, therefore, to be limited only as indicated by the scope
of the claims appended hereto.
