What's in the array? If there are object references, you should know that combos and listboxes maintain an internal array of strings (which you can access via .list collection). I figure there's no way to convert object to string. You may store sys(1272, loObj) values into the array, though, or have references to your objects in some other array which will not be copied to the listbox's rowsource.
