Hi Miyako, >I think we need to set reasonable limits on how the commands is expected to be >used, >before we device that its performance is "poor".
Sorry, maybe you are right and I shouldn't have called it poor performance, but it was my feeling because the command takes 10 times longer to execute than all other commands >is it really reasonable to insert 400 columns in one call? When customers ask for showing 10 listboxes at once on screen, with each listbox having 20 columns I don't know if it is reasonable, but as you probably know customer is king. Even worse, customers want 20 columns per listbox, but than are making 60% invisible So, I could do a lot to make things faster. Maybe, at first only create listboxes that are visible, and maybe even only create at first columns that are visible. But I prefer not to. >at what point in developer did you notice the "poor performance"? I must say I don't quite remember, because it has been a while. We first had the issue with some forms that were less important, and not so heavily used But I am sure it began when converting from one 4D version to another I believe it was when we converted our app from 4D v2004 to 4D v13 >the command name suggests that it is designed to insert a single column. >so you can imagine that it goes through the same check list for every call. So this sounds to me that a command LISTBOX INSERT COLUMNS would be a great addition, maybe with a width parameter at the same time >but the speed issue discussed in this thread, >seem to me like a case where a command has been used in a way for which it was >not designed. We use listboxes a lot and we really like them (We use array listboxes by the way, populated by an Oracle DB). I think 4D invests a lot of time in making listboxes more advanced, and they succeed very well. But I don't agree that inserting 400 columns in a list is something really spectacular. When this command isn't designed for this, maybe they can give me another command that IS designed for this. ********************************************************************** 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 **********************************************************************
