GetAsyncKeyState() "key pressed"

hello, when you press a key you can use the
GetAsyncKeyState();
function, but how do i do if i wan't to get the key you havé pressed

Code:

if (Getapressedkey(vk_shift)) // code dosent work.
{
cout << "you have pressed on shift";
}

The proper way to use GetAsyncKeyState is to BitAND the return value with 0x8000.

Code:

if (GetAsyncKeyState(VK_SHIFT) & 0x8000)
{
   // The key is currently down
}

You can also get a list of key states by calling GetKeyboardState.

Code:

unsigned char KeyStates[256];
GetKeyboardState(KeyStates);

for (int i = 0; i < 256; i++)
{
      if (KeyStates[i] & 0x8000)
      {
            // The keyboard key that 'i' represents is currently held down.
      }
}
