Abstract: A method and system that allows client code such as drawing code to remain in the client application yet allows the drawing code to be used in a control such as an ActiveX® control. A page including the control is created at a client window, and the client instructs a browser to render the page, whereby the control is instantiated. The control is provided with a handle to the client window, and using the handle, walks up the chain of its parent windows sending messages to locate the client window. Via the message, when the client window is located, the control sends its control window handle to the client window, whereby the client window is able to subclass the control window. The client is then able to perform operations in the control window such as draw reports, charts, graphs and the like therein.
