You call a form method you've added the same way you call any other event/method. In your VALID method for BOTH the textboxes you'd put

Thisform.SetButton()
return .t.

** SetButton Method
if !empty(Thisform.textbox1.value ) .and. !empty(thisform.textbox2.value)
   Thisform.Button1.enabled = .t.
   ....
else
   Thisform.Button1.enabled = .f.
   ....
endif

The same code is called from both (or more) textboxes. You can even pass parameters so the buttons could be set differently under different circumstances, but using the same method code.

Hope this makes it a little clearer.
