C++ 如何将用户按键存储在变量中

Question

So, I already know that by using if (GetAsyncKeyState()) I can check if the user presses a specific key. But what I need is to check if the user presses any key and to store that key that the user pressed inside a variable. Is there any easy way to do that?

Answer 1

First, _getch could read a single character from the console without echoing the character. But it has limitations, it cannot read all keys.

Then, GetKeyboardState can get the status of the 256 virtual keys. But it cannot detect the key event between two calls.

You could register key down event with RawInput or LowLevelKeyboard hook , Check this sample , you will get the Virtual-Key in input.data.keyboard.VKey . You could create a thread to wait and get the key event, instead of polling to check key status.

Answer 2

I'm guessing you're trying to get input without the user pressing 'Enter', in that case see this post's answer .
