I'm haveing a slight problem with bitblt. I have a form and a picturebox. The form is to be drawn upon and the picturebox is just for temporary storage. I put a Timer on the form and set it every second to update and copy the content of the form into the picturebox then put it back on the form to the left of one pixel. Like a moving chart. Like the task manager CPU chart. See what i'm saying? Hope I explained good enough. Thank you.
