[RESOLVED] Problems with System.Net.Mail

[ulv81]

Hello.

When I use the code below to send an e-mail from my form, the mail is not sent before the program is closed...

Anybody have any idea why this is so?!

        'create the mail message
        Dim mail As New MailMessage

        'set the addresses
        mail.From = New MailAddress("[email protected]")
        mail.To.Add("[email protected]")

        'set the content
        mail.Subject = "Mail Subject here."
        mail.Body = "Mail body here."
        mail.IsBodyHtml = False

        'send the message
        Dim smtp As New SmtpClient("YOUR SMTP SERVER")
        smtp.Credentials = New System.Net.NetworkCredential("Username", "Password")

        Try
            smtp.Send(mail)

        Finally
            mail.Dispose()
            smtp = Nothing

        End Try

Add a Catch block to your Try block and then you can actually see what the error is that is undoubtedly being thrown and is currently hidden from you... Alternatively, while you are still writing the program like this then you could just remove the Try block altogether so that any exceptions are thrown in the debugger and you can easily look at all of the information available with the exception

EDIT: Actually it seems I was wrong, your current code should still actually throw exceptions. However, just to be sure, if you stick a Catch block in there then do you get any exceptions thrown? For example:

Try
            smtp.Send(mail)
Catch ex As Exception
          MessageBox.Show(ex.Message)
Finally
            mail.Dispose()
            smtp = Nothing

End Try
