Display CheckBoxList Selections

I was needing to do a CheckBoxList that would talley up the results, and show a graphic if nothing was checked, and hide the graphic if something was checked. I found the following somewhere and tweaked it a little:

  Sub Check(ByVal sender As Object, ByVal e As EventArgs)
        Dim i As Object

        Label4.Text = "<p>Selected Item(s):</p>"

        For i = 0 To txtCheckBox.Items.Count - 1

            If txtCheckBox.Items(i).Selected Then
                Image6.Visible = False
                Label4.Text += txtCheckBox.Items(i).Text + "<br />"
            ElseIf i = 0 Then
                Image6.Visible = True
            End If

    End Sub

     <asp:CheckBoxList ID="txtCheckBox" runat="server" TextAlign="left" AutoPostBack="True" OnSelectedIndexChanged="Check">
                        <asp:ListItem Text="One" />
                        <asp:ListItem Text="Two" />
                        <asp:ListItem Text="Three" />
                        <asp:ListItem Text="Four" />
                    <asp:Label ID="Label4" runat="server" Text=""></asp:Label>
                    <asp:Image ID="Image6" runat="server" Visible="True" ImageUrl="img/ValidateWarning.png" />
