Mouse background hook

Question

Hi!

I am trying to hook mouseevents in the background but I don't get everything to work :/


public UserActivityHook actHook;
        private void mouseclicker_Load(object sender, EventArgs e)
        {
            actHook = new UserActivityHook(); // create an instance

            // hang on events
            actHook.OnMouseActivity+=new MouseEventHandler(MouseMoved);
            actHook.KeyDown+=new KeyEventHandler(MyKeyDown);
            actHook.KeyPress+=new KeyPressEventHandler(MyKeyPress);
            actHook.KeyUp+=new KeyEventHandler(MyKeyUp);
        }

        public void MyKeyDown(object sender, MouseEventArgs e)
        {
            MessageBox.Show("CLICK");
        }

the problem is:
public UserActivityHook actHook;
The type or namespace name 'UserActivityHook' could not be found (are you missing a using directive or an assembly reference?)

That error message do I got.

Please help me out here :)
