Hi all,

I have a form with a FormKeyUp event handler intended to intercept the Esc key, and do something, as below (semi-pseudo-code).

TForm1::FormKeyUp(Sender, Key) {
  if (Key == 27)
    ShowMessage("Esc key pressed");
}

TForm1::Button1Click(Sender) {
  MessageDlg("Proceed?", mtConfirmation, TMsgDlgButtons() <<
     mbYes << mbCancel, 0);

  // Can I put some code here to stop FormKeyUp firing when
  // the user presses Esc?
}

The problem I'm having - when a piece of code elsewhere pops up a dialog box with a Cancel option, if the user presses "Esc" to cancel the dialog box, not only is the dialog box cancelled, the onkeyup event is being fired off as well!

Can I include a line to stop the Esc key press firing other events, or can I maybe unhook the OnKeyUp event handler before the dialog and rehook it after the dialog box?

Thanks in advance,

Russ
