CWinApp::OnIdle - updating active doc

In a MDI app, I need to make updates to the active child document in the app's OnIdle() event.  How can I get a pointer to the active document from the app class?  And, most importantly, will I be able to call functions that I have added by subclassing CMDIChildWnd when I get the pointer to it.  Also, I'm not using doc/view.  MFC is confusing the hell out of me, so any help would be wonderful!

In your App class, GetMainWnd() returns a CWnd* pointer to your main window, so it needs to be cast...

   CMDIFrameWnd* mainwnd = (CMDIFrameWnd*)GetMainWnd();

Then, get the document with...

   CMyDocument* doc = (CMyDocument*)mainwnd->GetActiveDocument();

And get the view with...

   CMyView* view = (CMyView*)mainwnd->GetActiveView();

Get the child window with...

   CMDIChildWnd* child = (CMDIChildWnd*)view->GetParent();

You should be able to call the functions...
