In c language using dev c/c++ (dont ask why, thats the enviroment I know well)
I want a sample code to create window and turn on off pixel. I want it to be as much as simple (with explanations if possible) and small the code.
Also how to read a key and how to make the whole program run in desktop's background as overlay (like winamp's avs visualizations, check how simple and fast it is; i think it access ONLY the bitmap of the image being displayed or something like this..)
Also, where can I find a manual for the windows.h commands?
