Generally, your approach will be to loop through the index values of all items in your source ListBox. If you're moving all items on the ListBox then for each item you'd call the AddItem method on your destination ListBox (using the index value to retrieve the text of the current item on your source ListBox). You would then call the ListBox RemoveItem method to remove the same item from your source ListBox.

If you're moving only selected items, then you'd still loop through all index values but you'd use the Selected property for each item on the source ListBox to determine if the item is selected. If it is, use the steps above to move the item.

Specifics on what you need to do varies however, depending on how you've set a few properties on your ListBoxes. A resource you'll find useful is the discussion on ListBoxes over at thevbprogrammer.com. Look at the section Example: Adding and Removing Items with Two ListBoxes; it includes examples of what you want to do.
