Global Hotkay is not responding

Question

I'm writing a program to move the cursor with just the arraw keys. The idea is to press the ctrl button and then the arrow keys to move the cursor. I have alreday done the moving bit and figured out how to get a smooth and humen like action. I just have a problem when it comes to the global hotkeys...

  [DllImport("user32.dll")]
    public static extern IntPtr FindWindow(String sClassName, String sAppName);

    [DllImport("user32.dll")]
    public static extern bool RegisterHotKey(IntPtr hWnd, int id, uint fsModifiers, uint vk);

I have set the DllImport in the global araea.

IntPtr thisWindow = FindWindow(null, "Form1");
        RegisterHotKey(thisWindow, 1, (uint)fsModifiers.Control, (uint)Keys.W);

Later in the Form1_Load I find the window and then later sets a hotkey, in this case it's Control + W (0x0002 + W)

protected override void  WndProc(ref Message keyPressed)
    {
        if (keyPressed.Msg == 0x0312)
        {

        }
        base.WndProc(ref keyPressed);
    }

Last I have this method which will detect if the hotkey was pressed, but when I press the hotkey, nothing happens. I have tried to set a brekpoint in (if (keyPressed.Msg == 0x0312)), but the breakpoint dose not go off. Why could this be?
