Hi Alan, Thanks for testing! This is great news, because then maybe there is something else going on. Remember, I only asked the community if this performance was normal behavior and if it could be confirmed. Clearly not by you.
I tested this on an HP Intel Core i7-4710MQ 2.50GHz laptop with 24G memory When showing the listboxes for the first time the arrays have 0 elements (after on load they are populated via 4D for OCI commands) Maybe it does matter how many listboxes are on the form? Maybe LISTBOX INSERT COLUMN becomes slower when more columns are inserted? Miyako explained clearly LISTBOX INSERT COLUMN is a UI element, and that there are graphic engine calls involved I use a 1920x1080 resolution. I think I am going to test the creation of 20 columns for 10 listboxes on a blank form and see what happens. Again, Thanks for testing Alan Gr, Piotr > I just tested LISTBOX INSERT COLUMN command on array based LB that takes only > 0 to 1 ms to complete on my MBP 2.90GHZ with 16G memory. I'm not sure if size > of array is the factor. ********************************************************************** 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 **********************************************************************
