Naw, I'm not bugging you...I'm "featuring" you.< g,d&r >

I'll play around with it. It's one of those things on my "Gee, wouldn't it be neat if I could..." list. The GetBitmapBits() is probably exactly what I need. I'd used GetDIBits() with Obj2BMP directly after the BitBlt() call, but since we're not dealing with DIBs here...

Many thanks,
