I just googled and got this[^] link. I hope it helps. Regards, Sandip.

There's no time to think! In fairness, he did miss out the magic "urgentz" word... Iain.

Wow! Guys, we are getting so many bitmap comparing questions for past couple of days, I seriously think we should ask Chris to create a new forum for 'Bitmap Comparison' questions :laugh: It's better to know some of the questions than all of the answers. Pravin.

Put a breakpoint at the start of your posted code and step through line by line. Are the LoadImage() calls succeeding? Are the SelectObject calls succeeding? Are any calls succeeding? :) Mark Mark Salsbery Microsoft MVP - Visual C++ :java:

I decided to made a supplement for your magic site. :-D

Why dont you use GetDIBits()?? BTW Please use Code block tags for posting code. Regards, Sandip.

Take care of the stride? For example, the bimap is 8 bit per pixel, and 10*10 in size. It is not neccesarry that every line contains 8*10 bits. You might use stride to locate the pixel in the bitmap data. MSDN: GDI+ BitmapData Stride INT Offset, in bytes, between consecutive scan lines of the bitmap. If the stride is positive, the bitmap is top-down. If the stride is negative, the bitmap is bottom-up. system
