Can I use a timer to update a label every x milliseconds

Question

This is my code:

Stopwatch timer = new Stopwatch();
timer.Start();
while (timer.ElapsedMilliseconds < 3000) {
    label1.Text = Convert.ToString( timer.El

You cannot update the UI in a tight loop like that, because while the UI thread is running that code, it isn't responding to paint events. You can do nasty things like "DoEvents()", but please don't... it would be better to just have a Timer and update the UI periodically when the timer event fires; every 50ms would be the absolute fastest I'd go, personally.
