    End Sub
    Private Sub ComboBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ComboBox1.SelectedIndexChanged
        Dim cb As ComboBox = DirectCast(sender, ComboBox)

        ' NOTE: comparisons are case sensitive
        If ComboBox2.Items.Contains(cb.SelectedItem) Then
            MessageBox.Show("'" & cb.SelectedItem.ToString & "' - is in CB2")
            ' this is where I think you want your code to
            ' be as there is a match
        Else
            MessageBox.Show("'" & cb.SelectedItem.ToString & "' - is NOT in CB2")
        End If
