Good morning, I'm a new member of the forum. I' trying from yesterday to use GetAsyncKeyState to create a program that uses the keyboard to be controlled. But I would like to understand why if I use like a argument of the function "A" or "a", i have the same result, so I tried to save into a file the keys that i pressed, and i found that the result was always, "A". And now i don't know how to do.
