    Me.Paragraphs(1).Range.InsertParagraphBefore()
    Dim ListBox1 As Microsoft.Office.Tools.Word.Controls. _
        ListBox = Me.Controls.AddListBox(0, 0, 90, 71.25F, _

    ListBox1.Items.Add("Second Item")
    ListBox1.SelectedIndex = 0
End Sub
private void WordAddListBox()
{
    this.Paragraphs[1].Range.InsertParagraphBefore();
    Microsoft.Office.Tools.Word.Controls.ListBox
