The following code example adds a ListBox control to the top of the worksheet, adds two items to the list box, and then selects the first item. To use this example, run it from the Sheet1 class in a document-level project.

Private Sub ExcelAddListBox()

        Dim ListBox1 As Microsoft.Office.Tools.Excel. _
            Controls.ListBox = Me.Controls.AddListBox( _
            0, 0, 90, 71.25, "ListBox1")

        ListBox1.Items.Add("First Item")
        ListBox1.Items.Add("Second Item")
        ListBox1.SelectedIndex = 0

    End Sub
private void ExcelAddListBox()
{

    Microsoft.Office.Tools.Excel.Controls.ListBox
         listBox1 = this.Controls.AddListBox(
         0, 0, 90, 71.25, "lisBox1");
