Simple Application to switch Primary dispay

My current set up for my computer is with a 17 inch monitor on my desk and my HDTV a few feet away. Every once in a while (generally when playing games) things work better when I switch my primary di开发者_如何学编程splay to my HDTV. I'm running vista, so things can become a huge pain, as I have to go through several windows just to switch.

I'm thinking of making a simple application that will simply switch my primary and secondary monitors. I've looked around here, codeprojects and the MSDN library and haven't gotten anywhere. Anyone know a basic algorithm to switch the monitors in C++/C#?

You know you can just press Windows + P to change the status of your monitors?

Hope that helps.
