C++ console keyboard events

c++, console, keyboard-events, windows

Solution

You can use `GetKeyState` or `GetAsyncKeyState`, but that won't give you keydown/keyup events. It will only tell you what keys are currently down.

So if you really need to get the keydown/keyup events, you could install a hook. A Console window has a window handle that is owned by code in Windows and a message pump, also owned by code in Windows.

You can get the window handle of of the console window by using GetConsoleWindowThen install a `WH_CALLWNDPROC` hook using SetWindowsHookEx to listen in on messages send to the console window.

You might try a `WH_MSGFILTER` hook instead. I don't know if this works for console windows, but it would generate less messages to be ignored if it does work.

Problem

Is there any way to get key events in a Windows console? I need a way to get keydown and keyup events quickly without a GUI. I've tried using getch(), but it doesn't get keyups and waits until a key has been pressed to return.
