Question : How my Dialog is gone!!

I'm just edit a little on my Dialog source code, It can built and can run but It exits immediately!!! I've traced which line is the reason and I found it in some part on "c:\...\mfc\src\dlgcore.cpp" ...

int CDialog::DoModal()
{
.
.

     TRY
     {
          // create modeless dialog
          AfxHookWindowCreate(this);
This line is my problem -->>     if (CreateDlgIndirect(lpDialogTemplate,
                              CWnd::FromHandle(hWndParent), hInst))
          {
               if (m_nFlags & WF_CONTINUEMODAL)
               {
                    // enter modal loop
                    DWORD dwFlags = MLF_SHOWONIDLE;
                    if (GetStyle() & DS_NOIDLEMSG)
                         dwFlags |= MLF_NOIDLEMSG;
                    VERIFY(RunModalLoop(dwFlags) == m_nModalResult);
               }

               // hide the window before enabling the parent, etc.
               if (m_hWnd != NULL)
                    SetWindowPos(NULL, 0, 0, 0, 0, SWP_HIDEWINDOW|
                         SWP_NOSIZE|SWP_NOMOVE|SWP_NOACTIVATE|SWP_NOZORDER);
          }
     }
Jump to here -->     CATCH_ALL(e)
     {
          DELETE_EXCEPTION(e);
          m_nModalResult = -1;
     }
     END_CATCH_ALL

     if (bEnableParent)
          ::EnableWindow(hWndParent, TRUE);
     if (hWndParent != NULL && ::GetActiveWindow() == m_hWnd)
          ::SetActiveWindow(hWndParent);

     // destroy modal window
     DestroyWindow();
     PostModal();

     // unlock/free resources as necessary
     if (m_lpszTemplateName != NULL || m_hDialogTemplate != NULL)
          UnlockResource(hDialogTemplate);
     if (m_lpszTemplateName != NULL)
          FreeResource(hDialogTemplate);

     return m_nModalResult;
}

It return -1, so sorry but I really don't know How do I solve the problem!? My OS is Win2K using VC++ 6.0 SP4 and This is a second time I found this same problem!

Thanks you for your time,
really thanks

Answer : How my Dialog is gone!!

Check this: If you deleted a control that had a member variable (defined within the class wizard), you also must delete these member variable.
