Set num lock?

Hi,

I found this post: http://www.codecomments.com/archive290-2005-5-489956.html


I tried it and it works, all you need to do is...

1. libs:

using System.Runtime.InteropServices;

2. DLLImport

[DllImport("user32.dll", CharSet=CharSet.Auto, ExactSpelling=true, CallingConvention=CallingConvention.Winapi)]

3. Declare the function you want to use from the DLL

private static extern short GetKeyState(int keyCode);

4. Declare a variable with the code for the NumLock Key

private const int VK_NUMLOCK = 0x90;

5. Declare a state function that will use the external function as source.

public bool IsKeyOn(int nKey){

return (GetKeyState(nKey) & 1) > 0;

}

6. Test it

MessageBox.Show("State: " + (IsKeyOn(VK_NUMLOCK) ? "YES" : "NO"));

Not sure if there is an easier way since this was posted in 2005 and may not be 2.0 framework, but i hope this helps,
