How to use c++ to write Extension to listen to document open or save events

Question

I want to listen to open mxd file event in arcmap extension. I find a interface:IDocumentEvents, but I don't know how to use it in C++ and What is the listener for IDocumentEvents.

The question is how to Call AtlAdvise to subscribe to the document events. For IActiveviewEvents, we can use CLSID_ActiveViewEventsListener, but for IDocumentEvents, what is the Listener?

I use  "AtlAdvise(m_spDocument, m_spVGEDocumentEvents, __uuidof(IDocumentEvents), &m_dwDocEventsCookie);"
sucessful. thankyou

The class that you are probably looking for is MxDocument:

http://resources.arcgis.com/en/help/arcobjects-net/componenthelp/000v/000v000000nn000000.htm

Steps:* Get IApplication
* From IApplication call get_Document to get IDocument
* Call AtlAdvise to subscribe to the document events

If the above is not sufficient information then I'd suggest to install and dig through the C++ samples associated with the ArcObjects SDK.

In general, programming in C# would be easier but your post indicated that you wanted to use C++.

Best of luck!
