I have a SDI app consisting of a CFormView main window...I added a button to exit the program, how do I get
the app to quit when I click on the button (i.e., I know that I need to close the main frame window...but what is
the best way to do this)?

While the above response will work...I get the following trace dump:

SENDING command id 0x03FE to CConvView target
PumpMessage - Received WM_QUIT
Warning: destroying CSingleDocTemplate with live document
Detected memory leaks!
Dumping objects ->

{14} File Conversion Utility: File wincore.cpp, Line 475, Assertion Failed!
ASSERT_VALID fails with illegal pointer

So I was actually looking for an approach that follows the MFC  framework exit procedure

Commented:
The cleanest way is to set the button ID to ID_APP_EXIT.
It follows the framework exit procedure.

Commented:
If you use PostQuitMessage, it will exits the message loop immediately and there is no proper cleanup.

In u'r view source file , add the foll code
void CFormTestView::OnButton2()
{
      // TODO: Add your control notification handler code here

      AfxGetMainWnd()->SendMessage(WM_CLOSE);
      
}

Button2 is the button in u'r FormView , on pressing which, WM_CLOSE is sent to the MainFrame. This will close the Appln on clicking the button in a Formview.
And there're no memory leaks also.

Hope this helps u.
Hope this works.

I was going to give this a "C" untill the comment by kalaru was added...his response was to the point and complete, earlier responses by engllf were a little off-the-cuff and not as well thought out.  If I know how to give 100 "A" points to kalaru, I'd do it!!

Thaks for both your help on this simple question.

Sorry engllf...I ment my earlier comment to apply mostly to rayb (the original responder) but didn't scoll up far enough to see his name when composing my message.  BTY, setting the button ID to ID_APP_EXIT has no effect...presses on the button were not handled and there was no action.  But thanks for trying to help!!.
