I guess what's not really clear is why this is all necessary. If the concept behind a Combobox is to select from a list or enter a value, why does it not handle that automatically? If I type a value in a Textbox I do not need to do a replace; the fact that I have it tied to a ControlSource is enough. I do understand why the AddItem would be used, but when do you need the AddListItem? It's a lot of coding to get the Combo to do what you would think would be native behaviour.

>AddItem and AddListItem methods of combobox add items to the list in combobox that is displayed when you hit the combobox drop down arrow. What is not clear here?
