Private Sub ExcelAddButton()

        Dim Button1 As Microsoft.Office.Tools.Excel. _
            Controls.Button = Me.Controls.AddButton( _
            0, 0, 56.25, 17.25, "Button1")
        Button1.Text = "OK" 

    End Sub
private void ExcelAddButton()
{

    Microsoft.Office.Tools.Excel.Controls.Button button1 =
        this.Controls.AddButton(0, 0, 56.25, 17.25,
        "button1");
