Retrieving a document pointer

I am trying to retrieve a pointer to the active document in my application from my CMainFrame class (which is derived from CMDIFrameWnd).
I am calling GetActiveDocument() but all Im getting is a NULL pointer. Any suggestions?

The documents in you MDI are associated with your CChildFrame objects (derived from CMDIChildWnd)!
So no Doc is related to your CMainFrame and you get a NULL pointer!
Call GetActiveDocument() in your CMDIChildWnd derived class and you will get the pointer to the doc attached with this class.

From what I remember you need to have a CMDIChildWnd as well.  I think these are then all registered with an CMultiDocTemplate that controls the whole process.  Apart from that Ive mainly used a app wizard to generate the code for a basic mdi.  If ya want that let me know and ill email it to you
