Moving Text & Graphics smoothly on a form!!

Question

Dear All I'm tring to build > using OnPaint event to draw a text on the form then I added a timer 'interval=10' to change the X-coordinate of the graphics object so it start moving to the left I noticed the following: 1. It is using more the 40% of the CPU utilization. 2. It is not smooth although I'm enabling DoubleBuffer. How can I build a smooth ticker/scroll such as the one which is used in the satellite TV channels for SMS Chat and breaking news?? Any ideas ? Please HELP!

Why don't you post your paint code for us to look at. I've done a number of windows painting jobs and I might be able to spot something wrong.

I resized the form to fit the scroll area so I'm painting the needed area only!

Hello my fellow programmer! Are you painting in a clipped region? In other words are you painting the whole form on the paint event or are you painting just the marquee/scrolling area.
