I have a class with base class CFrameWnd. I need to have access to the activedocument as soon as the dialog box starts without any user input. I've tried accessing it from oncreate functions but because the activedocument isn't created yet, the pointer is to nothing. Are there any functions in the CFrameWnd I can override to have access to the activedocument? I hope this makes sense. This is the first time I've done something like this, any help is appreciated. Thank you so much.
It's in the Visual C++ FAQ

I can access the document no problem. If the user selects an option, once it's created, I can access it. But I need to have a thread accessing it as soon as it is created. I need to run this thread from CMainFrame as soon as the the document is created:
Doc* pDoc = static_cast<Doc*>(GetActiveDocument());
CWinThread* recvThread = AfxBeginThread(&recv, reinterpret_cast<void*>(pDoc));
Perhaps your document should call a function in your CMainFrame class and pass a pointer to itself when it's created.Quote:

How about InitialUpdateFrame. It even receives a CDocument pointer as an argument.Quote:

Yes that works. Thank you very much.Quote:
