Preventing ESC to kill a dialog box

Overrid OnClose() and leave it empty.
void CMyDialog::OnClose()
{
}

Alt+F4 also goes to DestroyWindow.
You could also use PreTranlateWindow in the dialog class to detect these messages and just 'swallow' them there. If they are not dispatched for further processing nothing will happen. That should also prevent the exceptios.

1. Overriding 'PreTranslateMessage()'

BOOL CYourDialog::PreTranslateMessage(MSG* pMsg)
{
// ENTER key
if((pMsg->message == WM_KEYDOWN) && (pMsg->wParam == VK_RETURN))
return TRUE;

// ESC key
if((pMsg->message == WM_KEYDOWN) && (pMsg->wParam == VK_ESCAPE))
return TRUE;

return CDialog::PreTranslateMessage(pMsg);
}

2. Overriding 'OnOK()' or 'OnCancel()'

// ENTER key
void CYourDialog::OnOK()
{
// CDialog::OnOK(); <-- Disable this line
}

// ESC key
void CYourDialog::OnCancel()
{
// CDialog::OnCancel(); <-- Disable this line
}

Thanks for your advice, but it doesn't go with my code. My CMyDlg::OnOk has a function to SetTimer() and to assign value to variables and CMyDlg::OnClose has a function to close the dlg only if m_bTimerOn is FALSE, otherwise button is diabled. I want to prevent the user from closing the dlgbox through "Esc" or "ALT+F4". I belive that the code needs to be defined in the CMyDlg::DestroyWindow() handler. I attached a snippet of my code:

BOOL CTimedUpdates::DestroyWindow()
{
if(m_bTimerOn)
return FALSE;
else
return CDialog::DestroyWindow();
}

This, however, gives me an application error (exception breakpoint) when the dlg is abruptly closed(via escape or alt F4) when the m_bTimerOn=TRUE.

Thanks for any help,
