If I hook a key event, can I prevent it goes to next event handler?

globalmousekeyhook is a nice API.

I am wondering if it is possible to eat an key event. For example, I hook the keydown event and capture "LControlKey".

        m_Events.KeyDown += OnKeyDown;

        private void OnKeyDown(object sender, KeyEventArgs e)
         {
             if (e.KeyCode == Keys.LControlKey)
             {
                    //do something
             }
       }

After Left Control is handled by function OnKeyDown, I want to drop this key event, so it won't be handled by the system.
Is it possible?

I think you just make the last thing you do e.Handled = true

It seems that does not work.
