John,

Yes and No < grin > In the Form.QueryUnload code put

if <  Required conditions are met >
   DoDefault()
   return .T.
else
   return .f.
endif

In your form release code put

if Thisform.QueryUnload()
   Thisform.release()
else
   <  message about why the user can't exit  >
endif

Thanks to Bruce for reminding me about the DoDefault().


QueryUnload() is code that is specifically designed to determine if the the form SHOULD be released. It's called first, before any control is deactivated, released, etc.
