The code you say must call the keydown event looks more like you add the event handler of the control twice.

C#

Control c =this.ActiveControl;
c.KeyDown+=new KeyEventHandler(c.KeyDown);

You should add a event handler to each control which has the following signature:

private void Control_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)

You can add this handler to a control like this:
c.KeyDown+=new KeyEventHandler(Control_KeyDown);

By the way, the ProcessCmdKey is overriding an internal routine of a control and is not an event handler. Those are two separate things.

Good luck!
