Is that practical possible.? common situation. when u want to delete a record, a pop up message will show up asking you to confirm it with (Yes button or No button) Do i have to create another form to achieve this? or just a syntax will do that job? thanks

Please refer 'MessageDlg' function:    

procedure TForm1.Button1Click(Sender: TObject);
begin
  case MessageDlg('please choice a answer', mtConfirmation, [mbYes, mbNo], 0) of
    mrYes: Showmessage('yes');
    mrNo: Showmessage('no');
    else showmessage('nothing');
  end;    end;

If the 'Yes' option is: ADOTable.Delete Where should I put that?

His code is 100% clear enough for where to put it.
