Good Afternoon,

I'm working on this section of chapter 15 and have read the previous threads about email / SSL issues but I'm not sure this is an SSL issue.

I have looked up the error using the F1-Help functionality in Visual Stuido 2008 and it sounds like it's a SQL problem.

This is the stack trace I'm getting when I enter the sign-up information into the sign-up wizard and hit the "Create User" button.

An existing connection was forcibly closed by the remote host

If this is due to the SSL issue just let me know and I'll go back to those threads and get this resolved.

Ernie

{edit} I get this error when I use my code as well as when I used the downloaded code for chapter 15.

By the off chance that this was an SSL issue I added the following code in my SignUp.aspx code behind page:

Protected Sub CreateUserWizard1_SendingMail..............
Dim mySmtpClient As SmtpClient = New SmtpClient()
mySmtpClient.EnableSsl = True
mySmtpClient.Send(e.Message)
e.Cancel = True
End Sub

I also added an Imports System.Net.Mail statement to the top of the code behind page.

I still received the error listed in the original post.

Thanks,

Ernie

{edit} I used the debugger and walked through the snippet above and found that the error generated when it hit the mySmtpClient.Send(e.Message) line. Since it's throwing the exception both with and without this code something must be happening right as it's about to send the email. As I walked through the debugger I watched as it pulled the .txt file for the email and inserted the user's name, etc., and it actually created the account for the user - saw the accounts when I was doing the rolemanager stuff later in the chapter. So it's just bombing when it tries to send the created email.

Hi Ernie,

Yes, it's indeed an SMTP error. You can see in the stack trace that it goes into System.Net.Mail.SmtpClient.Send and then crashes.

There could be a number of reasons for this problem. For example, you may be using the wrong SMTP server. Or you server indeed requires SSL and you're not providing the correct port number. Or maybe a firewall is set up to block SMTP.

Which SMTP server are you using? If you're using an external one (ISP, Gmail etc) does the external party provide more information about required settings?

Cheers,

Imar
