C++ Syntax	HRESULT EditGraph()

IltmmPlay *pPlay;

/* pointer to an interface */

Registers the current graph and runs the DirectShow GraphEdit utility.

S_OK	The function was successful.
<> S_OK	An error occurred. Refer to the Error Codes or the HRESULT error codes in the DirectShow documentation.

Comments

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 GraphEdit’s "Connect" menu option to view the registered graph. When done, exit GraphEdit, and click on the dialog’s ‘OK’ button to continue program execution.

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