WinAPI: How to get cap lock status?

Question

How can I turn caps lock on or off? I tried to find it, but all I find is to turn it on or off, which is the exact opposite of what I'm looking for.

I am trying to do this in both C ++ and Delphi.
Please, help

Answer 1

You want the GetKeyState () function:

with VK_CAPITAL key code. The remaining virtual key codes are here:

Answer 2

I found a link and below code snippet that can help you

if ((GetKeyState(VK_CAPITAL) & 0x0001)!=0) AfxMessageBox("Caps Lock ON!"); else AfxMessageBox("Caps Lock OFF!"); 

Answer 3

Use GetAsyncKeyState with VK_CAPITAL (0x14)
