Abstract

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.

Claims

1. A computer-readable medium containing a control comprising:

a container-independent control component for providing container independent functionality to a container;

a container-dependent control component for providing container dependent functionality of the container; and

a receiving component that receives a request to perform functionality of the control, determines whether the request is to perform functionality provided by the container-independent control component or the container-dependent control component, and requests the determined control component to perform the requested functionality.

2. The computer-readable medium of claim 1, further comprising a site component for interfacing between the control and the container wherein the control invokes the functionality of the container through the site component and the container invokes the functionality of the control through the site component.

3. The computer-readable medium of claim 1 wherein the control provides functionality through a plurality of interfaces with each interface having a plurality of methods and properties.

4. The computer-readable medium of claim 1 wherein the container-dependent control component provides functionality through a plurality of interfaces with each interface having a plurality of methods and properties.

5. The computer-readable medium of claim 1 wherein the container-dependent control component has a dispatching component for early bound access and late bound access to the functionality of the container-independent control and the container-dependent control component.

6. The computer-readable medium of claim 1 wherein the container-dependent control component and the container-independent control have associated binding information, loading information and type information and wherein the container-dependent control component has a type library component for providing access to the binding information, the loading information and the type information of the container-dependent control component and the control.

7. The computer-readable medium of claim 1 wherein the container-dependent control component and the container-independent control component have groupings of properties comprising property pages, and wherein the container-dependent control component has a property page component for providing access to the property pages of the container-dependent control component and the container-independent control component.

8. The computer-readable medium of claim 1 wherein the container-dependent control component and the container-independent control component generate events, and wherein the container-dependent control component has an event component for providing access to the container for registering for the events generated by the container-dependent control component and the control.

9. The computer-readable medium of claim 8 wherein the event component includes a sending means for sending an event to the container when the container-dependent control component generates the event and for sending the event to the container when the container-independent control component generates the event.

10. A computer system comprising:

a container-independent control component for providing container independent functionality to a container;

a container-dependent control component for providing container dependent functionality of the container; and

a receiving component that receives a request to perform functionality of the control, determines whether the request is to perform functionality provided by the container-independent control component or the container-dependent control component, and requests the determined control component to perform the requested functionality.

11. The computer system of claim 10, further comprising a site component for interfacing between the control and the container wherein the control invokes the functionality of the container through the site component and the container invokes the functionality of the control through the site component.

12. The computer system of claim 10 wherein the control provides functionality through a plurality of interfaces with each interface having a plurality of methods and properties.

13. The computer system of claim 10 wherein the container-dependent control component provides functionality through a plurality of interfaces with each interface having a plurality of methods and properties.

14. The computer system of claim 10 wherein the container-dependent control component has a dispatching component for early bound access and late bound access to the functionality of the container-independent control and the container-dependent control component.

15. The computer system of claim 10 wherein the container-dependent control component and the container-independent control have associated binding information, loading information and type information and wherein the container-dependent control component has a type library component for providing access to the binding information, the loading information and the type information of the container-dependent control component and the control.

16. The computer system of claim 10 wherein the container-dependent control component and the container-independent control component have groupings of properties comprising property pages, and wherein the container-dependent control component has a property page component for providing access to the property pages of the container-dependent control component and the container-independent control component.

17. The computer system of claim 10 wherein the container-dependent control component and the container-independent control component generate events, and wherein the container-dependent control component has an event component for providing access to the container for registering for the events generated by the container-dependent control component and the control.

18. The computer system of claim 17 wherein the event component includes a sending means for sending an event to the container when the container-dependent control component generates the event and for sending the event to the container when the container-independent control component generates the event.
