problem with modeless!...

hi!
my main application is a dialog based app.i created a modeless dialog box as below
BOOL CMDApp::InitInstance()
{
AfxEnableControlContainer();
#ifdef _AFXDLL
Enable3Controls();
#else
Enable3ControlsStatic();
#endif
CMDDlg *dlg= new CMDDlg;
dlg->Create();
m_pMainWnd = dlg;
return TRUE;
}
i destroyed it using..
void CMDDlg::OnCancel()
{
CMDDlg::DestroyWindow();
}

now my problem is that when the user presses the ESC key the dialog box vanishes.i want the dialog box to stay.
how can modify this?..what is the reason for the dialog box to vanish even after overriding the OnCancel() function?

As you mentioned ESC invokes OnCancel.

Remove the DestroyWindow from OnCancel - leaving the handler blank.

Toad224

If you remove the "CMDDlg::DestroyWindow();" from the code, then your dialog should not close when Esc is pressed.

You should use:

void CMDDlg::OnCancel()
{
}

to destroy it instead.

I hate to ask this...but your answer differs from mine how?

As an alternative - if you wish **just** to disable the Escape key...

BOOL CTestDlg::PreTranslateMessage(MSG* pMsg)
{
      if (pMsg->message == WM_KEYDOWN)
      {
            if (pMsg->wParam == VK_ESCAPE)
            {
                  return TRUE;
            }
      }
      return CDialog::PreTranslateMessage(pMsg);
}
