Hi, I have a program that writes some graphical info to the screen and to a bitmap that is the same size as the screen, when I get a WM_PAINT message I just use BitBlt to copy the bitmap to the screen, thus redrawing the screen. Works great when using black&white bitmap, when I added colors, when I copy the bitmap to the screen the screen turns blank. I suspect the problem is with the ROP2 code that I am using and/or the raster operation that controls the way BitBlt works. I am stuck, could a kind sole give me some pointers... Thank you, gary.
