    You don't have to set that as an extern, its public and part of CMainFrame... means you should be able to reach it from any CMainFrame... what are you trying to do?

      As far as I understand your question, you can access it like below.

      ((CPipeLineApp*)AfxGetApp())->dgDlg;

        still not sure what the problem is... if CPipeLineApp is derived from CWinApp, then he owns the CMainFrame, so you have complete access to it...

                see what ozer wrote above... i think i misunderstood your question, i thought you were trying to access cmainframe from cwinapp, a trivial operation, but you're really trying to access dgDlg (who is owned the cwinapp) from the cmainframe... that's not as trivial (but almost... ;P ) Happy coding! :)
