Hi Chip, in addition to Wayne's post, see "Shared and unshared objects" in this page: <http://doc.4d.com/4Dv16/4D/16/Interaction-between-components-and-host-databases.300-3048908.en.html> For example, in a component: • 'Get pointer' and 'RESOLVE POINTER' will read component's variables • all "system variables" are distinct from host <http://doc.4d.com/4Dv16/4D/16/Variables-systeme.300-3036051.fr.html> etc. Personal thought about UI: I avoid it in components, except "little pieces of puzzle" like dialogs, progress, some widgets… In a development I'm on, an important part of the UI relies on a component - some kind of table navigator / advanced user mode, if you want - and it's really a nightmare to maintain. -- Arnaud de Montard ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **********************************************************************
