CDO.Message Error

[Jacques Cooper]

Hello,

We're developing a small SMTP client application. When
we run the program we get the following error message:

"could not access 'CDO.Message' object"

We get the error message when we set the
"SmtpMail.SmtpServer" value. However, if
we don't specify the server name we don't
receive the email message either.

// C# source code snippet.
//

MailMessage mm = new MailMessage();

mm.From = "su*****@mycompany.com";
mm.To = "te*******@mycompany.com";
mm.Cc = "";
mm.Bcc = "";
mm.Subject = "Test Subject";
mm.Body = "Test Body";

SmtpMail.SmtpServer = "mycompany.com";

SmtpMail.Send(mm);

// end of code snippet

Any ideas about what could be causing the error message?

TIA,
Jacques

Hi Jacques,

Does your application run in asp.net?
The asp.net account may not have the enough privilege to access the network
an create sockets.
It DOES, however, have privileges to create a socket to the local machine
(127.0.0.1 localhost).
If you plan on using SmtpMail from an ASP.NET app, you MUST use your local
SMTP Service, and not an external one.
Alternatively, you could increase the privileges of the ASPNET account

or does your application multithread?
If it is multithreading, your mail code should run in the main form thread.

Hope this helps,

Hello Jeffrey,

Thank you for responding to my posting. However, we are not using ASP.NET.
This is a stand-alone C# application.

Any ideas?

Thanks,
Jacques

Hi Jacques,

Thanks for your feedback.
Is your smtp server on your machine or on remote machine?
I think you can try to setup a smtp server on your machine. In your
application, if you do not specify the smtpserver, the .Net will search the
smtp service on your machine.
If your application can send the email through your machine's smtp service,
I think you should check whether your remote smtp server support this
feature.
Also, you can check the permission of C:\Inetpub\mailroot.

Actually, there are a lot of possible reason for this error message. The
link below contains a lot of discussion about this error, you can check it:

Try putting a try catch round your code, Then print Exception.ToString()
With the SMTP exceptions, the message allways says "could not access
'CDO.Message' object", but if you do a Exception.ToString(), it gives you
more detail
