You need both to issue NODEFAULT and to RETURN .F. if the form is not to be released. By doing this you can allow for a command button to test if a form is to be closed. Generally, the code would look something like:

* QueryUnload
llresult = < Logical condition indicating whether or not to close the form. >
IF llresult && In the case of .T. equalling don't close the form
  NODEFAULT
ENDIF
RETURN NOT llresult && Same as above
* Close command button click event
IF ThisForm.QueryUnload()
  ThisForm.Release
ENDIF
