Usually it should behave like a "normal" listbox, PLUS it's got the additional text-property for combo style.
So, you'd get the selected value like this (out of my head):
Code:
combo1.List(combo1.ListIndex)
You should really just select a combobox on a form and press F1, and then see what it can do. Or get some basic / fundamental tutorial or guideline.
I'm almost tempted to say RTFM, but I since it's Christmas and not that bad, well...
