Ciao,
sono un novizio in ambito asp.net,
mi serve realizzare un modulo per l'invio di e-mail,
nella rete ho trovato questo codice:

codice:
<script language="vb" runat="server">

Sub btnSendFeedback_Click(sender as Object, e as EventArgs)

  'Create an instance of the MailMessage class
  Dim objMM as New MailMessage()

  'Set the properties - send the email to the person who filled out the
  'feedback form.
  objMM.To = "info@miosito.it"
  objMM.From = txtEmail.Text

  

  'Send the email in text format
  objMM.BodyFormat = MailFormat.Text
  '(to send HTML format, change MailFormat.Text to MailFormat.Html)

  'Set the priority - options are High, Low, and Normal
  objMM.Priority = MailPriority.Normal

  'Set the subject
  objMM.Subject = "4GuysFromRolla.com - Feedback"

  'Set the body
  objMM.Body = "At " + DateTime.Now + " feedback was sent from an ASP.NET " & _
               "Web page.  Below you will find the feedback message " & _
               "send by " & txtName.Text & "." & vbCrLf & vbCrLf & _
               "---------------------------------------" & vbCrLf & vbCrLf & _
               txtMessage.Text & vbCrLf

  
  'Specify to use the default Smtp Server
  SmtpMail.SmtpServer = ""
  
  'Now, to send the message, use the Send method of the SmtpMail class
  SmtpMail.Send(objMM)


  panelSendEmail.Visible = false
  panelMailSent.Visible = true
End Sub

</script>

<html>
<body>
  <asp:panel id="panelSendEmail" runat="server">
    <form id="Form1" runat="server">
      <h2>Contatti</h2>

      Nome:
      <asp:textbox id="txtName" runat="server" />
      


      Indirizzo Email:
      <asp:textbox id="txtEmail" runat="server" />
      



      Messaggio:

      <asp:textbox id="txtMessage" TextMode="MultiLine"
                      Columns="40" Rows="10" runat="server" />
      



      <asp:button runat="server" id="btnSendFeedback" Text="Send Feedback!"
                  OnClick="btnSendFeedback_Click" />
    </form>
  </asp:panel>


  <asp:panel id="panelMailSent" runat="server" Visible="False">
    
  </asp:panel>
</body>
</html>
ma quando uplodo la pagina, il modulo contatti non appare proprio!
come posso fare??
a presto
