This [ICODE]System.Threading.Thread.Sleep(100);[/ICODE] makes your code to wait for 100 ms. But it doesn't yield CPU time to other threads if that's what you want. Use [ICODE]Application.DoEvents();[/ICODE] to yield some CPU time to other threads as well.

Yes. You have to yield CPU time to UI thread in order to keep its message pump working: [CODE=C#]for (int i = 0; i < 200; i++) { label1.Text = i.ToString(); label1.Refresh(); Application.DoEvents(); System.Threading.Thread.Sleep(10); }[/CODE]
