How inhibe the ENTER and ESC KEYS ?

[youssef]

Hi,
I created a project. I deleted the OK and CANCEL buttons. But when I execute my project and I press the ESC or ENTER KEYS, the project is stopped.

How can I do for inhibe this KEYS?

Best Regards

Yes, windows still inteprete ESC key as the OnCancel message handler, because OnCancel is in CDialog class, it still can be invoked even if you delete the Cancel button.

The solution is : override the PreTranslateMessage function
and modify it:

BOOL CTestDlgDlg:reTranslateMessage(MSG* pMsg)
{

if (pMsg->message == WM_KEYDOWN){
if( pMsg->wParam == VK_ESCAPE) return true;
}
return CDialog:reTranslateMessage(pMsg);
}

This will ingore the ESC key.

I don't think return key will close your dialog after you delete the OK button from it. If it does happen, pls let's know.
