I have a program that starts constantly juggles between 3 separate timers.

The main thread of my application has a while loop which constantly checks if a global variable has been set to true and if it has, it will stop one timer and launch two other ones – one continuously, another to stop it automatically if it isn’t commanded to stop for whatever reason.

This while loop has a condition of (1==1) so that it runs forever.

In the task manager (XP) I see that my program is using up 50% of cpu on a more or less idle system.

Is there a way to decrease that number by decreasing the speed of the while loop or something?

Thanks.

    Yes, you could insert a call to Thread.Sleep(n). With a granularity of ~20 ms.

    But the far better option would be using a Waithandle.
    Your main thread would Wait on the handle and the end of the timer code would signal it to wake up.
