combobox1.AddItem "ABC"
combobox1.Additem "DEF"

Now to determine which was chosen:

Private Sub ComboBox1_Click()
Msgbox "You chose " & combobox1.list(combobox1.listindex)

Just another variation of what sirBounty has written:

I would trap the
---
ComboBox1.SelectedIndexChanged event instead of the click event.
---
and in the selectedIndexChanged event, do something like this:

MessageBox.Show("You chose" + combobox1.selectedValue);

//or

MessageBox.Show("You chose" + ComboBox1.SelectedItem.ToString())

Well, why are we assuming that he is using VB or .NET?

Ok, let's have a go at Java (since we don't know which language you are on, we might as well give you solutions for the ones which we know). Solutions for VB and .NET have already been posted.

Populating a combo-box:

list.add ( yourString ) ;

(you can do that in a loop, changing the values of yourString or using a String array or a Collection)

Getting the value that the use selected:

String selectedValue = list.getSelectedItem () ;

OR:

int selectedIndex = list.getSelectedIndex () ;
String selectedItem = list.getItem ( selectedIndex ) ;
