Hi guys,

Could someone help me on this please, I followed what was explained in the tutorial video for sending email in www.asp.net but I get this error :

http://screencast.com/t/37mxw6kvTGot

Here is the code :

Imports System.Net.Mail
Partial Class frmDemandeCompte
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        hlAccueil.Text = "Retour page de login"
        hlAccueil.NavigateUrl = HttpContext.Current.Application("defaultLoginPage")

        lblEmailUtilisateur.Text = HttpContext.Current.Application("lblEmailUtilisateur")
        lblEmailUtilisateurConfirm.Text = HttpContext.Current.Application("lblEmailUtilisateurConfirm")
        lblNom.Text = HttpContext.Current.Application("lblNom")
        lblObjet.Text = HttpContext.Current.Application("lblObjetEmail")
        lblPrenom.Text = HttpContext.Current.Application("lblPrenom")
        ccBody.Content = "Merci de me créer un compte <br />" + txtNom.Text + " " + txtPrenom.Text
    End Sub
    Protected Sub btnEnvoyer_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnEnvoyer.Click
        SendMail()
    End Sub
    Private Sub SendMail()
        Dim mailMessage As System.Net.Mail.MailMessage

        mailMessage.From = New MailAddress("clasdf@gmail.com")
        mailMessage.To.Add(New MailAddress("xaven@hotmail.fr"))
        mailMessage.Subject = txtObjet.Text.Trim()
        mailMessage.Body = ccBody.Content.Trim()

        Dim smtpClient As New SmtpClient()
        Dim userState As Object = mailMessage

        AddHandler smtpClient.SendCompleted, AddressOf smtpClient_OnCompleted
        smtpClient.SendAsync(mailMessage, userState)
    End Sub
    Public Sub smtpClient_OnCompleted(ByVal sender As Object, ByVal e As System.ComponentModel.AsyncCompletedEventArgs)
        Dim mailMessage As MailMessage

        mailMessage = CType(e.UserState, MailMessage)

        If (e.Cancelled) Then
            lblMessage.Text = "Sending of email message was cancelled. Address=" + mailMessage.To(0).Address
        End If
        If Not (e.Error Is Nothing) Then
            lblMessage.Text = "Error occured, info :" + e.Error.Message
        Else
            lblMessage.Text = "Mail sent successfully"
        End If
    End Sub
End Class

Thanks in advance

you forgot to create an instance of your mailmessage

you can do it like this:

    Dim mailMessage As System.Net.Mail.MailMessage
    mailMessage = New System.Net.Mail.MailMessage

or like this:

    Dim mailMessage As New System.Net.Mail.MailMessage

try this

Step 1:

Public Sub SendEmail(ByVal Toaddress as string, ByVal body as string, ByVal subject as string, ByVal ishtml as Boolean)

            Dim Msg As New MailMessage

                        Try  

                  Msg.From = New MailAddress(ConfigurationManager.AppSettings("EmailFromAddres").ToString, 

                                     ConfigurationManager.AppSettings("EmailFromAddressDisplayName").ToString)

                  Msg.To.Add(New MailAddress(Toaddress))

                   Msg.Subject = subject

                  Msg.Body = body

                  Msg.IsBodyHtml = ishtml

                  Msg.Priority = MailPriority.Normal

                  ' to connect to the exchange server by using info in the web.config

                  Dim client As New SmtpClient(ConfigurationManager.AppSettings("ExchangeServerName").ToString())

            client.DeliveryMethod = SmtpDeliveryMethod.Network

                  client.UseDefaultCredentials = True

                  client.Port = ConfigurationManager.AppSettings("ExchangeServerPort").ToString()

                  client.Timeout = ConfigurationManager.AppSettings("ExchangeServerTimeout").ToString()

                  'send the email

                  Try

                        client.Send(Msg)

                  Catch ex As Exception

                        Exit Sub

                  End Try

            Catch ex As Exception

            Finally

                  Msg = Nothing

            End Try

      End Sub

Step 2:

change your web.config to include the following information about your company's exchange server

<configuration>
     <appSettings>
        <add key="ExchangeServerName" value="CWcwcw"/>
        <add key="ExchangeServerPort" value="25"/>
        <add key="ExchangeServerTimeout" value="999999"/>
        <add key="EmailFromAddres" value="something@somedomain.com"/>
        <add key="EmailFromAddressDisplayName" value="Mr Someone"/>
        
    </appSettings>


</configuration>

jitendramcu I can't see your link.

Now i get this error message :

Error occured, info :Le serveur SMTP requiert une connexion sécurisée ou le client n'était pas authentifié. La réponse du serveur était : 5.7.0 Must issue a STARTTLS command first

Here is what I have in my webconfig file :

<system.net>
    <mailSettings>
      <smtp>
        <network host="smtp.live.com"  port="25" userName ="xaadsn@hotmail.fr" password="********" />
      </smtp>
    </mailSettings>
  </system.net>

What did I miss?

Download the sample code and use it

hello,

We need to enable SSL for it to work, here is a working sample.

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
    
        Dim mailMessage As New System.Net.Mail.MailMessage

        mailMessage.To.Add(New MailAddress("toSomeone@gmail.com"))
        mailMessage.From = New MailAddress("fromMe@hotmail.com")

        mailMessage.Subject = "my test subject"
        mailMessage.Body = "my test body"
        mailMessage.IsBodyHtml = True

        Dim smtpClient As New SmtpClient()
        smtpClient.EnableSsl = True

        Dim userState As Object = mailMessage

        AddHandler smtpClient.SendCompleted, AddressOf smtpClient_OnCompleted
        smtpClient.SendAsync(mailMessage, userState)

    End Sub


 Public Sub smtpClient_OnCompleted(ByVal sender As Object, ByVal e As System.ComponentModel.AsyncCompletedEventArgs)
        Dim mailMessage As MailMessage

        mailMessage = CType(e.UserState, MailMessage)

        If (e.Cancelled) Then
            lblMessage.Text = "Sending of email message was cancelled. Address=" + mailMessage.To(0).Address
        End If
        If Not (e.Error Is Nothing) Then
            lblMessage.Text = "Error occured, info :" + e.Error.Message
        Else
            lblMessage.Text = "Mail sent successfully"
        End If
    End Sub

Hey;

I'm so sorry because I don't know VB but I use this code for sending email for c#. I hope you can understand and use it for yourself:

string from = "*********@gmail.com"; //Replace this with your own correct Gmail Address

string to = useremail.Text; //Replace this with the Email Address to whom you want to send the mail

System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();

mail.To.Add(to);

mail.From = new MailAddress(from, "Your Topic Message", System.Text.Encoding.UTF8);

mail.Subject = "Write the subject of your email";

mail.SubjectEncoding = System.Text.Encoding.UTF8;

string strBody = "<p>YOU </p>" +

"<p>CAN</p>" +

"<p>WRITE WHATEVER</p>" +

"<p>YOU WANT AS A BODY OF YOUR MESSAGE</p>" +

"<p>Thank you!</p>" +

"<p>Best Regards</p>";

 mail.Body = strBody;  //Put your mail body to strBody to show it in your email...

mail.BodyEncoding = System.Text.Encoding.UTF8;

mail.IsBodyHtml = true;

mail.Priority = MailPriority.High;  //Your Email will have a priority so it will have red "!"

SmtpClient client = new SmtpClient();

//Add the Creddentials- use your own email id and password

 client.Credentials = new System.Net.NetworkCredential(from, "YOUR EMAIL'S PASSWORD");

client.Port = 587; // Gmail works on this port

client.Host = "smtp.gmail.com";

client.EnableSsl = true; //Gmail works on Server Secured Layer

try

{

client.Send(mail);

}

catch (Exception ex)

{

Exception ex2 = ex;

string errorMessage = string.Empty;

while (ex2 != null)

{

errorMessage += ex2.ToString();

ex2 = ex2.InnerException;

}

HttpContext.Current.Response.Write(errorMessage);

} // end try

Hope, it works for you as well... If there is a problem and doesn't work, just let me know because may be I copied that code wrong from my application.
