theForger's Win32 API Tutorial
I know you already posted this. You either didn't read it or didn't understand it.
If you didn't read it; read it.
If you didn't understand it then ask questions about the parts that you don't understand.
A lot of people here (myself included) learnt basic Win32 API programming using that tutorial. The tutorial is very good and I am neither willing nor able to write a better tutorial than it just for your benefit.
If you want specific answers you need to ask specific questions.
Sorry for all the line breaks.
