Luca,

Research the ReleaseType property of the form. It is set when the closebox is clicked. I don't recall the numnber for the closebox but it is in the helpfile. Code like this in the valid will do what you want.

IF Thisform.ReleaseType = [the number for the close Box]
   RETURN .T.
ENDIF
*** The rest of the valid goes here
