Because dialog controls handle keyboard events. You can do this using PreTranslateMessage:
BOOL CMyDlg::PreTranslateMessag
{
if( pMsg->message == WM_KEYDOWN )
{
// test here pMsg->wParam and pMsg->lParam to get message details
// according to WM_KEYDOWN message definition
}
return CDialog::PreTranslateMessa
}
