Buttons used in Message Dialog
A message dialog can be written to ask a question yet ignore the result or only have one button yet check the result.
This statement asks the user the question but ignores the result:
MessageDlg(‘Are you sure ?’, mtConfirmation, [mbYes,mbNo], 0);
It should probably read as this:
If MessageDlg(‘Are you sure ?’, mtConfirmation, [mbYes,mbNo],
0)=mrNo then exit;
