When you additem to a list, you have added the whole row. IOW, after the first additem, you have got both columns available. So, all you need to do is something like the following:

myCombo.AddItem("FirstCol Item",1)
myCombo.list( myCombo.listIndex,2) = "SecondCol Item"
/pre>

You'll want to check the syntax--I've only had 2 cups of coffee this morning ;-)

>myCombo.AddItem("FirstCol Item",1)
>myCombo.AddItem("SecondCol Item",2)
