>What exactly is the difference between a Cbo and List Box? or is it more in the use later on down the development road?? I'm confused!

I assume you mean a combo box and a dropdown list box ( Style property of 0 or 1 ). The dropdown list is a read only list, that is you can't type anything new into the textbox area. The combo box allows you to type new data into the text box area. This allows you to test on the Value and DisplayValue properties to see if the user typed a new entry into the control. If they did, Value and DisplayValue will be different. You can then do whatever processing you need to validate and add the new item to the list.
