Ans:
Items.Add
If the Sorted property of the ListBox is set to true, the item is inserted into the list alphabetically. Otherwise, the item is inserted at the end of the list. To insert an item into the list box at a specific position, use the Insert method. To add a set of items to the list box in a single operation, use the AddRange method. If you want to use the Add method to add a large number of items to the list, use the BeginUpdate and EndUpdate methods to prevent the ListBox from repainting each time an item is added to the list until all items are added to the list. When adding items to a ListBox, it is more efficient to sort the items first and then add new items.
