Description
Generates an OnChanged event.
Call PropChanged when the property specified by the DispID (or PropertyName) parameter changes. PropChanged generates an OnChanged event using the IPropertyNotifySink interface.
When possible, call this procedure with the DispID rather than the PropertyName because it is more efficient. Calling PropChanged with the PropertyName first looks up the DispID from the given PropertyName before generating the event.
