If you used DoModel() API, for the child dialog to show it, then the child dialog is model.Instead if you used other API to show the dialog,say, ShowWindow(..),then its modeless

By default, the escape key triggers the OnCancel() event of a modal dialog. You must override the OnCancel function in your dialog class. Example from MSDN:

void MyDialog::OnCancel() 
{
   // TODO: Add extra cleanup here
   
   // Ensure that you reset all the values back to the
   // ones before modification. This handler is called
   // when the user doesn't want to save the changes.
   
   if ( AfxMessageBox("Are you sure you want to abort the changes?", 
         MB_YESNO) == IDNO )
      return; // Give the user a chance if he has unknowingly hit the
              // Cancel button. If he says No, return. Don't reset. If
              // Yes, go ahead and reset the values and close the dialog. 

   CDialog::OnCancel();
}

OnCancel is not only called by hitting ESC key, also called by closing dialog box, for settling this, I think u may overwrite CDialog::PreTranslateMessage funcion like this. BOOL CdlgtestDlg::PreTranslateMessage(MSG* pMsg) { if(pMsg->hwnd == m_hWnd || ::IsChild(m_hWnd,pMsg->hwnd) && (pMsg->message == WM_KEYDOWN || pMsg->message == WM_KEYUP)) { if(pMsg->wParam == VK_ESCAPE) return TRUE; } return CDialog::PreTranslateMessage(pMsg); }
