Handling ID_APP_EXIT message.

I'm trying to write a routine which will prompt the user to save
an unsaved document (I'm not using the serialize functions).  

I'd like the routine to simply check a boolean (which is in the document
class) and then call my OnFileSave routine (in the document class)
if needed.

I'm trying to have the ID_APP_EXIT message handled in the document
class.  The problem is that after this message has been handled, I
would still like to exit the application.  How do I do this?  I can't
seem to be able to call the CWinApp:ExitInstance() function from
the document class.

The other approach would be to handle the ID_APP_EXIT message
in the application class, but I would somehow need to get it
to call my save function in the document class.

What's my best course of action?

CWnd* pwndMain = (CWnd*)AfxGetMainWnd();
pwndMain->SendMessage (WM_CLOSE,0,0);


By the way the comment of "CJ S" is not a good method which will cause a memory leak.
