You can not deal 'with handling messages'[1], how can I believe that you are kind of good with Windows API?
Some advice...Work your way through the tutorial on MSDN[2], it will give you a good grounding in what you need to know by the time you get to Module 3 (Windows Graphics).
I read Module 3 already yesterday late and it didn't help much....It just brags too much about hard system crap and I just need to know the exact codes or how to implement the logic of those exact codes to get what I want done. I'll worry about all that hard drive tech stuff later on....
Prolonged discussions about how a line is drawn and raster images is not what I want; it doesn't help me.....How to use the CODES does.
