I have been meaning to give a little back to this community for a while now. I have had many questions answered either directly or indirectly by the community. Thank you.
Attached is a few classes I created to make working with UI controls a bit easier. Included is a list box control, sortable list box control, and shuttle box control. All three classes build on top of each other. There is also a tester application that shows how to use the controls.
This code is tested on CS2 and seems to work on CS3 but have not spent much time there yet.
Enjoy!
