Question

A timer is being used in my C# application to determine if an expected event has occured in a timely fassion. This is how I am currently attempting to do this:

// At some point in the application where the triggering event has just occured.
   // Now, the expected event should happen within the next second.
   timeout = false;
   timer1.Interval = 1000; // Set timeout for 1 second.
   timer1.Start();

timer1_Tick(object sender, EventArgs e)
{
   timeout = true;
}

// At some point in the application where the expected event has occured.
   timer1.Stop();

// At a later point in the application where the timeout is
// checked, before procedding.
   if ( timeout )
   {
      // Do something.
   }

Now, what I am wondering is when the Start() or Stop() member methods are called, does that cause the timer count to reset? I am using Microsoft Visual C# 2008 Express Edition. Thanks.

When you call Stop() it effectively resets the timer back to 0, from the linked page:

Calling Start after you have disabled
a Timer by calling Stop will cause
the Timer to restart the interrupted
interval. If your Timer is set for a
5000-millisecond interval, and you
call Stop at around 3000 milliseconds,
calling Start will cause the Timer
to wait 5000 milliseconds before
raising the Tick event.
