Modaless Dialog Box
-
Hi, I want to display a Modaless Dialog box instead of Modal dialog box in mfc application.So,I called Create function instead of DoModal() inside the InitInstance() but I am getting Debug Assertion Failed error. CDlg dlg; m_pMainWnd = &dlg; int nResponse = dlg.Create(IDD_DIALOG1); if(nResponse) dlg.ShowWindow(SW_SHOW); else MessageBox(NULL,_T("Error"),_T("Error"),MB_OK); I dont know where made the mistake???

While creating dialog box pass the second parameter as NULL. After successful creation of dialog you have to assign the address of the dialog to the m_pMainWnd. int nResponse = dlg.Create(IDD_DIALOG1, NULL); if(nResponse) { m_pMainWnd = &dlg; m_pMainWnd->ShowWindow(SW_SHOW); } else {} I think this will solve your problem.

Thank you, I have to globally define the dlg instance, CMfc_Modaless_vc6Dlg dlg; CWnd* m_pMainWnd = &dlg; while I do this after the application instance creation it is giving the same Debug Assertion Failed problem.I cannot declare the Dlg locally,so what i can do for this? Siddharth

Why would you say this?

You should not have to do this.

Thank you, I am getting Debug Assertion in afxwin1.ini file. I told that we have to create dlg instance globally because,when i create it inside the initinstance then dialog will be disappeared when the it is out of the scope,so I wanted it as a global one.

The file is over 1100 lines long. Which one?

Make it a member of your
CWinApp-derived class instead.

So are you directly or indirectly calling
AfxGetResourceHandle()?

No, I am not calling that function directly. But global declaration where I am doing Is it correct? After the App instance creation,I am creating Dlg instance.

I also asked about an indirect call. When the assertion fires, check the call stack.

Not in my opinion. Until you actually solve the problem, you'll not know for sure if it's correct or not.
