Hi

I am trying to use the following code to send an email using System.Net.Mail
It asks for the local machine IP Address
How do I find this programmatically?

    Public Sub SendEmail(ByVal MsgFrom As String, ByVal MsgTo As String, ByVal MsgSubject As String, ByVal MsgBody As String)

        Try

            '  Pass in the message information to a new MailMessage

            Dim msg As New Net.Mail.MailMessage(MsgFrom, MsgTo, MsgSubject, MsgBody)



            '   Create an SmtpClient to send the e-mail

            Dim mailClient As New SmtpClient("127.0.0.1")  '  = local machine IP Address

            '  Use the Windows credentials of the current User

            mailClient.UseDefaultCredentials = True



            ' Pass the message to the mail server

            mailClient.Send(msg)

            '  Optional user reassurance:

            'MsgBox(String.Format("Message Subject ' {0} ' successfully sent From {1} To {2}", MsgSubject, MsgFrom, MsgTo), "EMail", Windows.Forms.MessageBoxButtons.OK)

            '  Housekeeping

            msg.Dispose()

        Catch ex As FormatException

            MsgBox(ex.Message & " :Format Exception")

        Catch ex As SmtpException

            MsgBox(ex.Message & " :SMTP Exception")

        End Try

    strHostName = System.Net.Dns.GetHostName()
    strIPAddress = System.Net.Dns.GetHostByName(strHostName).AddressList(0).ToString()

This needs to be the IP address of your email server. Do you have an SMTP server running on the local machine? If not, do you have access to a server? If yes, use that. If not, use a public server like gmail.

Hi MacroShadow
I get 'GetHostByName' is obsolete for the line
 System.Net.Dns.GetHostByName(strHostName).AddressList(0).ToString()
