How to sort combo and list box contents?

Hi. I am just wondering if there are any pre-defined methods for arranging the contents of a combo or a list box in alphabetical order. Or would I have to write the algorithm myself? If so, any advice on how I can write it in such a way that it won't slow down the program by too much? The contents of the list can run to as high as 100 items. TIA

There is a Sort property on both controls. Set it to true and it will sort alphabetically.
