摘要:
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.

摘要:
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.
