Dissection of attached sample code

Dim msg As New Aspose.Network.Mail.MailMessage

We first create a MailMessage instance, which is the container holding the messages or files to send by the SmtpClient
msg.From = New Aspose.Network.Mail.MailAddress("email@domain.com")

Set the From email address, let's say the sender of the message

msg.Subject = "hello"

Set the Subject of the message
'email bodies
msg.TextBody = "Please open this mail message by browser"

Set the TextBody of the message, if the mail client of receipients can not read html message, use the TextBody
msg.HtmlBody = "this is a html body"

Set the HtmlBody of the message

'receipients

msg.To.Add(New Aspose.Network.Mail.MailAddress("email.address@domain.com"))
msg.To.Add(New Aspose.Network.Mail.MailAddress("email.address@domain.com"))

Set receipients' email address

'attached a local file to the mail
'msg.Attachments.Add(New Aspose.Network.Mail.Attachment("..\..\Module1.vb"))

Add attachement to the mail

'send mail by SmtpClient
Dim client As Aspose.Network.Mail.SmtpClient = New SmtpClient("mail.aspose.com")
client.Port = 25
client.Username = "user"
client.Password = "password"

Creat a SmtpClient instance to connect to your mail server, send the message
Try
'send this message
client.Send(msg)
Catch e As Exception
Console.WriteLine(e)
End Try
Console.Read()

Feel free to ping me with any problems. We are glad to provide any help or demonstrations if you need.

Thanks

This one works. In what respect does it differ from the delivered examples ?

The previous failed demo does not set the receiptient address.

We have updated the setup package.

  • New demo for pop3/Imap is included.
  • Hotfix for reading Outlook Message.
