I'm going to assume you don't actually want to capture the screen, your question cannot make sense. I'm guessing you simply want to make your window maximized to occupy the full screen. Put the template generated code back the way it was, simply change the ShowWindow call.
Found this on google: Difficulties with Screen Capture, C/C++... Try to understand the code and adjust it to you needs.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
