Two items: 1. You hitting your system's memory limits?
2. Do all the controls go to the same table or are they spread over multiple tables and views? Check for duplicate column names. (Same column names in a Table and a View) or (same column name in two different tables) = duplicates if used in the same form or report. It forced me to learn about using aliases in views. Sounds like you have 40 items a page. I had similar issues with an Enhanced tab with lots of pages with dense info entry. All those lookups need to get loaded when you start up. Ended up breaking it up into a Form with a menu system using Bit and Speed buttons. Each menu button has its own specific Forms with about 40 items each and is isolated from the others. Load 40 items compared to 650 at one time. Lot less memory, better control over names, unneeded variables cleared at form exit, and easier to track what was going on. Runs quick.

Within all those pages/tabs, I have about 650 controls. Labels, var labels, bit buttons, var Lookup Combo boxes, var edit, var lookup ListViews etc... I've been noticing lately as I've been adding on more controls, while in design mode; things are not acting as usual. Such as after I run form in design mode and exit the running of the form via a button, I get an error "List Index out of Bounds ###". The ### changes from 648, 649 ... 659, 660. If I take one control off the form (I think any kind of control, button, listview); I can stop the error from happening. Running form not directly from design mode, I do not get the error message. After running form via design mode: When back in design mode, and I save the form, this "save" icon does not always gray out (save completed) Also when I click on a control (again in design mode), it does not update the status lower bar that shows the controls attributes (variable, width, height...) Have I reached a per form limit of some kind? Total number of controls per form? Total number of tabs/pages per tab control? Or is there something else that is causing my form to act strangely in while in design mode??? Any tips - clues would be greatly appreciated! Regards, Lena QMI Security Solutions X1037
