First choice is Timer & second is Thread.

Application.DoEvents() doesn't work, The reasen for this is following: I need to drow lines after every 3 seconds, so I need some pouse for 3 second. I think using the timer will help.

If I were you, I'd avoid the use of Thread.Sleep() in the UI thread.

Even if you can get it to work by calling Application.DoEvents(), the delay produced may not be constant because of the time taken to process pending events.

I'd use a System.Windows.Forms.Timer instead.

after the line of code where you draw this line, add this line of code...

Application.DoEvents();
