This function will display a modal dialog box indicating that the graph has been registered. The current thread is suspended during this time. The toolkit then attempts to invoke the GraphEdit utility from the DirectShow SDK. You can use GraphEdits "Connect" menu option to view the registered graph. When done, exit GraphEdit, and click on the dialogs OK button to continue program execution.

This function is intended for debugging purposes only. Modification of the graph can render it unusable.
