An extensible object model enables extending the standard methods and/or properties of an extensible object for an application through an extension object proffered at run time by an extension package Information about the extension package is registered in a database when the package is installed, and the database is used to resolve references to the extended methods and/or properties upon execution of the application. In one aspect of the invention, the extension object is cached when first referenced and subsequent references to the extension while the application is executing are resolved to the cache.

A method and system for adding application defined properties and application defined property sheet pages are provided. The application defined properties may be added to a list of system defined properties. Once added, the application defined properties may be displayed and edited. In addition, a user may select several objects, display the properties common to all of the objects in a list, and edit the common properties. Moreover, application defined property sheet pages may be added to a set of system defined property sheet pages. A user may then display and edit the application defined property sheet pages. Also, a user may select several objects, display the properties common to all of the objects on a per-property browsing list, and edit the common properties. In addition, a user may select several objects, display the property sheet pages common to all of the objects, and edit the properties on these property sheet pages. Furthermore a user may switch between viewing a property in a list of properties and viewing a property on a property sheet page.

An object interface control system that provides a mechanism for identifying the functionality available at an interface separately from the interface itself. A COM implementation provides a new function call named QueryService which is similar to the existing QueryInterface function call. Services are defined which include a set of functionality. The set of functionality for a service is expressed through a family of interfaces. When requesting a pointer to a function using the QueryService call, one specifies the service name and the interface name. Different services may utilize the same interface. Different services may utilize the same interface through which each service provides different functionality. A QueryService function call may return a pointer to an interface on the same object to which the call was placed or it may return a pointer to an interface on a different object. Object identity is not assumed with the QueryService function call and hence queries for services can be easily delegated.

The scripting engine interface provides the capability to interconnect any suitably written application or server with any scripting language. The implementation of the scripting engine itself (language, syntax, persistent format, execution model, and the like) is left entirely to the vendor, and the scripting engine need not come from the same vendor as the host application. The scripting engine interface implements this capability using a set of interfaces, the two most important ones being IActiveScriptSite (implemented by the host application) and IActiveScript (implemented by the language engine.) Together, these interfaces allow a host application to inform a scripting engine about the functionality that can be scripted and to define the scripts that the scripting engine should execute, either immediately or in response to user actions such as mouse clicks. The scripting engine interface redefines the handshake that is required between two specific types of software components in a manner not previously done. Unlike past scripting engine interfaces, which define a unique and proprietary way of hooking up to an application, the interface described here provides a universal hookup mechanism that is simple and direct.

A componentizing object designer is used to define a componentization of visual forms and other object-oriented technologies. The componentized object designer includes a set of tightly integrated protocols enabling Component Object Model (COM) objects to replace standard built-in visual form and other objects. The componentized object designer allows the design-time object and the run-time object to differ in implementation. The componentized object designer allows class identifiers for the run-time objects which are different than design-time objects. With a different class identifier, the run-time object can be saved as an object which is radically different from the design-time object. This enables the run-time object to be stored in a different object library than the design-time object. The componentized object designer allows for different persistence formats to be saved for run-time objects. The persistence formats for the run-time objects can be significantly smaller in size compared to the original design-time objects. This is important when the run-time object needs to be downloaded over a computer network like the Internet or an intranet.

The present invention provides a control architecture that enables the sharing of controls between many containers. That is, the present invention provides for developing a control in such a manner that it may be used on dissimilar containers without modification. Thus, the control architecture of the present invention is a container independent control architecture that allows for the sharing of code. Since the container independent control architecture of the present invention provides for code sharing, the time required for developing controls and containers is reduced by the present invention. The present invention is utilized by splitting the functionality performed by a control into container dependent functionality and container independent functionality. After splitting the functionality, the present invention embodies the container independent functionality into a control and the container dependent functionality into an extended control. The present invention then combines the extended control and the control so as to appear as a single entity to the container.

Licensing is aided by checking the object designer for licensing data, and embedding a licensing key into the run-time object.

An improved method and system for binding data is provided. In a preferred embodiment of the present invention, bound controls transfer data to cursors through a binding manager. The binding manager is also responsible for transferring data from a cursor to a bound control. In addition, a preferred embodiment of the present invention provides for a notification mechanism as part of the cursor. The notification mechanism of the cursor of the preferred embodiment provides synchronization amongst all binding managers utilizing the cursor. The notification mechanism of the preferred embodiment provides synchronization amongst all binding managers by invoking event handlers registered by the binding managers. The event handlers are invoked by the cursor both before and after an operation is performed by the cursor.
