>Is there a way to have a form take up the entire screen no matter which machine runs it? I've run an app on a machine with a 17" monitor and it looks totally different, only taking up only partial sctreen. Even some machine with the same screen as mine, the same happens.

You can use the _screen.WindowState = 2 to size the basic screen at startup. Use Vlad Shevchenko's Re-size program (it's in the Files section) if you want each control to remain in the same proportion to the screen, no matter what the screen resolution is.
