C# Moving bar/image on Picturebox -

-

i'm creating windows form application, in picturebox have static background (from image). i'm willing add moving bar/image @ bottom of background (like in news tv). bar/image created dynamically (depending on received data) , it's size (width) far greater of picturebox (only part of bar/image visible @ time). how can achieve in manner won't kill neither cpu nor ram? time ago did creating image of background + visible part of bar , refreshing operation , box lot, wasn't smartest idea due high usage of cpu , memory.

thanks in advance ! :)
