Abstract
Abstract An operating system provides extensions through which application developers may extend the capabilities of a shell of the operating system. For example, application developers may add menu items to context menus for objects that are visible within an integrated system name space. In addition, developers may add property sheet pages for such objects. Application developers also have the option of providing per-instance icons for each instance of an object. Application developers may provide data object extension handlers for customizing data sources on a per-object class basis and may provide drop target extension handlers on a per-object class basis to customize drop target behavior. Developers may additionally provide copy-hook handlers to regulate file system operations on objects. Developers may also extend the functionality provided by the shell of the operating system by adding their own custom name spaces to the integrated system name space. The mechanism provided by the operating system to add such a name space is polymorphic and transparent to users.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
210 words
In a data processing system having a video display, an object having an associated object identifier, the object belonging to an associated object class, the object class having an associated object class identifier which is different than the object identifier, the object class having an associated context menu that specifies operations that may be performed relative to objects of the object class, an operating system that includes a shell which specifies a predefined first set of menu items for the context menu associated with the object class, and an application program installed under the operating system, wherein the object and object class are associated with the application, a method comprising the steps of: providing a database of entries holding configuration information associated with the context menu; providing a context menu handler for adding to the context menu a second set of menu items not provided by the shell, said context menu handler and said second set of menu items provided by the application program and being independent of the operating system; registering the second set of menu items in the database of configuration information in association with the object class identifier; and when the object is accessed, running the context menu handler to display the second set of menu items.
Claim 2
Dependent Claim
210 words
In a data processing system having a video display, an object having an associated object identifier, the object belonging to an associated object class, the object class having an associated object class identifier which is different than the object identifier, the object class having an associated context menu that specifies operations that may be performed relative to objects of the object class, an operating system that includes a shell which specifies a predefined first set of menu items for the context menu associated with the object class, and an application program installed under the operating system, wherein the object and object class are associated with the application, a method comprising the steps of: providing a database of entries holding configuration information associated with the context menu; providing a context menu handler for adding to the context menu a second set of menu items not provided by the shell, said context menu handler and said second set of menu items provided by the application program and being independent of the operating system; registering the second set of menu items in the database of configuration information in association with the object class identifier; and when the object is accessed, running the context menu handler to display the second set of menu items.
Claim 3
Dependent Claim
48 words
The method of claim 1, further comprising the step of adding menu items that are registered in the database to the context menu of the object such that the context menu of the object includes both the predefined menu items and the added menu items that are registered.
Claim 4
Dependent Claim
18 words
The method of claim 2, further comprising the step of displaying the context menu on the video display.
Claim 5
Dependent Claim
52 words
The method of claim 1, further comprising the steps of: receiving a selection from the context menu by a user of one of the added menu items; and calling the code identified in the entry in the database for the menu item that has been selected in order to execute the code.
Claim 6
Dependent Claim
236 words
In a data processing system having a video display, an object having an associated object identifier, the object belonging to an associated object class, the object class having an associated object class identifier which is different than the object identifier, the object class having an associated context menu that specifies operations that may be performed relative to objects of the object class, a database of entries holding configuration information, an operating system that includes a shell which specifies a predefined first set of menu items for the context menu associated with the object class, and an application program installed under the operating system, wherein the object and object class are associated with the application and have an associated object identifier and object class identifier, respectively, a computer-readable medium holding computer-executable instructions for performing a method comprising the steps of: providing a database of entries holding configuration information associated with the context menu; providing a context menu handler for adding to the context menu a second set of menu items not provided by the shell, said context menu handler and said second set of menu items provided by the application program and being independent of the operating system; registering the second set of menu items in the database of configuration information in association with the object class identifier; and when the object is accessed, running the context menu handler to display the second set of menu items.
Claim 7
Dependent Claim
236 words
In a data processing system having a video display, an object having an associated object identifier, the object belonging to an associated object class, the object class having an associated object class identifier which is different than the object identifier, the object class having an associated context menu that specifies operations that may be performed relative to objects of the object class, a database of entries holding configuration information, an operating system that includes a shell which specifies a predefined first set of menu items for the context menu associated with the object class, and an application program installed under the operating system, wherein the object and object class are associated with the application and have an associated object identifier and object class identifier, respectively, a computer-readable medium holding computer-executable instructions for performing a method comprising the steps of: providing a database of entries holding configuration information associated with the context menu; providing a context menu handler for adding to the context menu a second set of menu items not provided by the shell, said context menu handler and said second set of menu items provided by the application program and being independent of the operating system; registering the second set of menu items in the database of configuration information in association with the object class identifier; and when the object is accessed, running the context menu handler to display the second set of menu items.
