I've just implemented a scrolling routine that uses the BitBlt functions in MS Windows SDK, however, when the screen is scrolled a noticable flash occurs as the screen is repainted. What I would like to know is how programs like Excel implement their scrolling stratergy where movements left and right ( or for that matter up or down) do not inccur a noticeable flash of the screen? Is there a way of implementing a duo screen buffer.. where one is shown while the other is repainted?
