Woops. I assumed that VFP 3 text boxes had the property too (they do in VFP 5 and later).

I don't have VFP 3, so I can't test, but you can try something like the following in the KeyPress event:

IF TYPE("THIS.Value") = "C"
	IF LEN(THIS.Value) >= LEN(THIS.InputMask)
		NODEFAULT
	ENDIF
ELSE
	IF LEN(ALLTRIM(STR(THIS.Value))) >= LEN(THIS.InputMask)
		NODEFAULT
	ENDIF
ENDIF

this will discard the keypress anytime the length of the value is already at the length of the input mask. I know, this should be automatic, but ....
