I wrote a program to display a bitmap using ImageMagick. The program allowed resizing of the window and scrolling of the image. It did not scroll smoothly at first - the screen flashed annoyingly. I found that the problem was in the InvalidateRect call. I had copied some code from a different program and the last argument was set to TRUE which blanks the window background before redrawing. Setting it to FALSE made the scroll very smooth. Best Wishes Pete To unsubscribe from this group, send an email to: [email protected] Your use of Yahoo!
