I'am so sorry .I've made a serious mistake.

class CPipeLineApp : public CWinApp
{
public:
CDengLu* dgDlg;
.....
};

I want to call dgDlg in class CMainFrame. I also want to call dgDlg's variables: name and pass Forwarding your help.

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...

[Albert Holguin]

...I'm thinking you don't really know the MFC framework?

[Albert Holguin]

ozer's right... my 5! [i forgot you can rate these!]

:( I'am a green hand.

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! :)

interesting quote... sounds familiar... :laugh:

[Ozer Karaagac]

But, I couldn't find out how I could save it as default in my settings. Do you know how?

[Albert Holguin]

Have no idea! ...i've only recently become an active participant in this forum... :doh:
