I haven't seen any advantages listed in this thread that would suggest it is better than a grid.

>>>Terry,
>>>Typically, the control source for the grid (or listbox) would be a cursor.
>>>So, I would have to loop through the cursor and add the rows to the listbox, correct? That could introduce a delay in the object appearing with data, correct?
>>>The idea of sorting without indexing is definately attractive.
