[RESOLVED] Pre-selecting item in ComboBox - "Operation is not allowed when the object is open"

[LuckyJack]

Hello.
In the form load event, I am populating a combobox with items from a database query. I then want to pre-select one of the items. This worked fine under VB6 but I am currently upgrading the code to .Net, and I am getting the error "Operation is not allowed when the object is open". I cannot seem to get by this. Below is my code.

NOTE: I tried using both methods: setting the Text property, as well as the SelectedIndex property (commented), and get the same error.

            i = 0
            Do While Not rs.EOF
                i = i + 1
                cboUsers.Items.Add((rs.Fields(0).Value))
                If rs.Fields(0).Value = LANID Then
                    cboUsers.Text = rs.Fields(0).Value
                    'cboUsers.SelectedIndex = i
                End If
                rs.MoveNext()
            Loop

Thanks in advance,
Paul
