If you want to set the current item (which is selected if the ListBox is in 
single selection mode), you must do MyListBox.Index = n, where n is the index 
of the item (between 0 and MyListBox.Count - 1)

If the ListBox is in multiple selection mode, then you can do 
MyListBox[n].Selected = TRUE / FALSE, to set the selected state of the n-th 
item.
