getKeyState(20)

[kilianvp]

I wanna check if CAPS Lock is on or off

According to the Windows API docs VK_CAPITAL is 0x14 = 20

But getKeyState(20) is always 0

WinCC OA doesn't use the Windows API?

Okay if i press they key while i execute getKeyState it works

Our code does:
SHORT status = ::GetKeyState(virtKey.getValue());
integerVar.setValue(status & 0x8000);
