We store small preview of the document (500 x 500) in data file, compressed it is few kB, but with lot of documents, database grows pretty fast (we have instances of ~20GB files.) We implemented preview of documents of individual client as a (scrollable) SVG pictures build from data from database - preview, name, size, creation date etc. Seems to work well even for large number of files, however we had to handle such action as selection highlighting, D&D etc. We tested picture arrays displayed by ALP and specialized plugins but this works for us quite well. Situation become more complex when user wants to edit stored documents in third party applications. I have not found a good solution how to find out when user ended editing. Ended up displaying small dialog where user clicks when has finished editing and then code moves document back to storage. -- Peter Bozek ********************************************************************** 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 **********************************************************************
