With this little amount of information noone is really able to tell what's the problem.

Maybe it's a problem with the automatically redraw of the background

Thank u coder777,
First I draw the graph using CDC in Picture Contrrol.
Second If i drawn the graph then, display the messagebox. That time i am not close the msgbox and move the msgbox various location.that time the graph is redrwn automatically. I find the problem in net, that problem called Flicker. I try to avoid the flickering problem but not use.
And also if resize the window that time same problem was occured.

No, it's not flicker. Flicker means that you see all the elements, but you see it permanent redrawing.

Your problem is that something disappear. This means either you don't draw youf stuff at that point/message or the background is drawn afterwards.
