HELP: Error in program, won't display bitmap!

Hello. I'm working on a text editor and a bitmpa viewer. I think that I have finished the program. I complile and I get 0 errors and 0 warnings. However, when I open the bitmap viewer in my program, (File -> Open Bitmap -> browse -> any bitmap, the bitmap flashes on and then off within one millisecond. All you can really see is a flash of color. If you keep clicking the mouse, it will keep displaying the flash of the picture. Could someone PLEASE help me? Thanks!

I don't know much about DrawState, so I don't know if that's your problem or not, but try using bitblt or something like that.
