Hilmar gave you the best answer, but once in a while this is needed.

There is no way that I know of to change the text of the invalid message. But you can prevent it all together or simulate it.

IF lThisIsAnError
  ?? CHR(7)
  WAIT WINDOW "That's Wrong!" NOWAIT  && You could use any form of notification here
  RETURN 0                            && use 0 instead of .F.
ENDIF
RETURN .T.
