Perhaps List.ListItemID is what you are looking for.

>When I click on an item in a listbox to select it, I am storing the value in the listbox to a variable. I would also like to store the listbox item number to a form property to determine which item was selected instead of stepping through the listbox as it is now (see code below). In other words, I do not allow multiselect on the listbox and I want to know what the 'nCnt' (see nCnt var below) value is when I click on an item. Is there anyway to determine that?
