It's been a long time since I last had to write a windows framework for my projects and I have forgotten some of the problems I solved in my old framework (which was lost due to a HD crash) such as changing the window style when switching from windowed mode to fullscreen mode. I used to use a couple of functions that would change the windows style without having to first kill the window and re creating it. They were standard win api functions, I just can't remember which ones... Anyone know what they are?
