Hi all

I need to develop an application that has to run just for let's say 45
minutes and then close.

What is the best way to do this.

I was thinking on using a Ttimer but I don't know if it's the best choice

any help

Something has to trigger you to wake up periodically and check to
see if it is time to shut down. Unless, of course, you're always
running, in which case you can just check every 100 times through
your loop. But nominally, you'd probably do fine with a TTimer.

Good luck.

Sure, why not?  Set the timer's interval to

const
  FortyFiveMinutes = 45 * (1/24/60);

And them

procedure TForm1.FormCreate(Sender: TObject);
begin
  Timer1.Interval := Round(FortyFiveMinutes) * 1000;
   Timer1.Enabled := True;
end;

And in the OnTimer --

procedure TForm1.Timer1Timer(Sender: TObject);
begin
  Close;
end;

Thank you for the info.

   if I use the  function to round the constant   FortyFiveMinutes = 45 *
(1/24/60);
   it returns 0.  the constant value is 0.03125 is this ok?? something i'm
missing
 could I just give 2700000 to the interval (45 in milliseconds I think)

Nick's expression for the interval was a bit odd. The correct
calculation would be 45 * 1000 * 60 = 2700000 as you noted.

Good luck.
