I am developing a custom textbox sub-class. I am monitoring each keystroke in the keypress event. Some keystrokes are obvious errors and I want to sound the "bell" when those keys are pressed rather than accept them. I specify NODEFAULT on those keystrokes and so I therefore do not accept them, but I want the user to be aware so that is why I want to sound the "bell". The users only look up when they hear a "bell". I cannot find a way to make the bell sound.

Can anyone help me?
