I want to display the temperature of the CPU/GPU using a graphic. My main purpose to do this project is that laptop users often have overheating problems when playing high performance games.
I already know how to get the temperature of the PC but I don't know how to display a graphic that is always on top even though there are games running in fullscreen.
The program "fraps" is exactly doing what I am looking for except that it shows the frames per second instead of the temperature.
So, how can I ensure that a graphic will be always on top?
