Sorry I didnt explain what I was looking for. All I want is to generate some kind of beeping noise or blinker when the user makes an error. At present I'm inputting all the user errors in a message box. Is there a way to create a beeping noise or some kind of other attraction that will get the user attention?

Penagate: Do you have to add any reference to use the Console.Beep? Cause I've been trying to use it but its not being recognized.
