IVisEventProc object (Visio)
The interface for handling event notifications in Microsoft Visio.
Remarks
In addition to the methods inherited from IDispatch, the IVisEventProc interface contains a single function, VisEventProc, which returns a Variant. Because IVisEventProc inherits from IDispatch and hence from IUnknown, you must implement the methods in those interfaces as well as the VisEventProc method.
To handle event notifications in Visio, create a class module that implements the IVisEventProc interface in Microsoft Visual Basic for Applications (VBA) or Microsoft Visual Basic, and then create an instance of this class to pass as an argument to the AddAdvise method of the EventList collection.
