Sending an email from VB.NET

    Public Function SendMail(ByVal s_mailfrom As String, ByVal s_mailto As String, ByVal s_subject As String, ByVal s_message As String) As Integer

        ' --- Send email
        ' imports system.net.mail

        ' --- Construct the message
        Dim mymessage As MailMessage
        mymessage = New MailMessage
        mymessage.To.Add(s_mailto)
        mymessage.From = New MailAddress(s_mailfrom)
        mymessage.Subject = s_subject
        mymessage.Body = s_message

        ' --- do the actual sending
        Dim mysmtp As New SmtpClient("your.smtp.server")
        mysmtp.Send(mymessage)

    End Function

To add an attachment from a file defined in the string s_filehandle, add the following to the code:

mymessage.Attachments.Add(New Attachment(s_filehandle))

To send html mail instead of plain text, add the following tag

mymessage.IsBodyHtml = True
