Sending email with VB.Net is easy. First, you have to add the webmail namespace:
Here is the source code:
Imports System.Web.Mail
Sub Send_Email()
Dim SmtpServer As SmtpMail
SmtpServer.SmtpServer = "your smtp server goes here"
Dim myMessage As MailMessage = New MailMessage()
myMessage.Body = "Hi, this is a test email using vb.net"
myMessage.From = "fromEmail"
myMessage.To = "toEMail"
myMessage.Subject = "test email"
SmtpServer.Send(myMessage)
End Sub
