How do I remove the comma from TextBox14.Text result. Code below

Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
        Dim Tbox9, Tbox11, Tbox12, Tbox13 As String
        Tbox9 = TextBox9.Text
        Tbox11 = TextBox11.Text
        Tbox12 = TextBox12.Text
        Tbox13 = TextBox13.Text
        Result = Tbox13 / (1.08 * (Tbox9 - Tbox11))
        TextBox14.Text = ShowResult
        TextBox14.Text = FormatNumber((Result), 0, )
        ShowResult = Tbox9 - Tbox11
        TextBox12.Text = ShowResult
    End Sub
End Class
