How can I restrict a textbox to take only one predefined string and throw an message box in else case

In my winform application I have a textbox that should only take a predefined local server address and throws an message box in the else case as soon as the focus changes from that textbox


See the Validating event. This event will fire when the control should be validated, which by default happens when the control loses focus.
