Is A Game Fullscreen Or Windowed?

Question

Is there anyway to know if a certain game is running on full screen or running as a window?

I need this because my application is for a game that can toggle between fullscreen and window mode and I need to act differently to each situation.

something like :

if (Fullscreen) {Act For Fullscreen} else {Act For Window Mode}

*The game isn't mine, it's another game. A real game.

It might be worth clarifying whether the game is yours or an external application. A few answers assume the former, where i think you mean the latter. — George Duckett, Jul 05 '11 at 15:03
Please try this. I've tried it on games. http://stackoverflow.com/a/35582683/168345 — sjlewis, Feb 23 '16 at 16:22

I assume that game is not written by you. You can use Win32 api http://www.pinvoke.net/default.aspx/user32.GetWindowPlacement

@user779444: What do you mean? If you are inside a method of your form class then exactly as I wrote (or `this.WindowState`). If not, then you have to have a form object - say it's myForm. Then you write `myForm.WindowState` – Armen Tsirunyan Jul 05 '11 at 15:53

It will probably depend on specific graphics technology you will be using rather than on WinForms API.

For example XNA (DirectX):

GraphicsDeviceManager graphics = new GraphicsDeviceManager(...); 

graphics.IsFullScreen = true;

Have you looked at the WindowState and FormWindowState enumeration?

A Full Screen application is a maximized window without borders.
