Why not put that code in separate method of the form and call it from Click event of that button?
i.e. Make a new method in that form name it BeforeExit, add a property in that form and call it BeforeExitIsExecuted

In Click event of that button:

thisform.BeforeExit()
thisform.Release()


**** or if you want to call that method no matter if the button is pressed or not put in Destroy event of the form:
thisform.BeforeExit()


*** in BeforeExit method:
IF NOT thisform.BeforeExitIsExecuted
   *** do your code here
   thisform.BeforeExitIsExecuted = .t.
ENDIF
