GetAsyncKeyState is global, even if my application is minimized, it will check for key input. Is there any way of doing it for a single application?

You could either check for input with GetAsyncKeyState only if your window is active, or you could just use Windows messages which does that for you. It all depends on what you're making.
I'm making a game, i need a key input system for a console based application.
There's a way of hooking async with one program...but how to?
As far as I know, no. I would try my first idea. Just check if your window is active using IsWindowEnabled, and if it is then check for input with GetAsyncKeyState.
Edit: This probably also belongs in Windows...
You really do not need to mess around with this is you used a real input API, such as DirectInput. It was made for games.

Code:if(GetAsyncKeyState(key) && GetFocus()==yourhwnd){ handle the input }

Since you will be using this in a game, you will go into your GetAsyncKeyState loop, so first you wanna check the GetFocus() == yourhwnd, and then go into your key waiting loop.

Just don't burn out the CPU. Check if the key was pressed down (or up) since the last call. It is a semi-buffered API, but it is better than nothing.
Although better would be to use a real buffered API such as that DirectInput & probably other input API offers.
