Hello all.
I searching a lot about this... but i'm fail.

My question is about "resolutions".
I want to create a simple game that recognize the resolution of the user's monitor. Its in a 1024x768 screen size.

Like if the program runs in a 800x600 monitor, the app automatic set the size to this.
If the program runs in a monitor with 1336x768, then the size changes automatic.

There's a way to when app runs, I can get and store in a var the x & y of user's monitor/resolution and set my app to this values?
I need what to do that? Its much hard to implement?

If someone can help me about this with tutorials, examples, extensions and anything that can do this.
Thanks to all! =D
