Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim myMessage As MailMessage = New MailMessage()

When I use this code (straight from Beginning ASP.Net 3.5) I get the following error message for Dim myMessage As MailMessage = New MailMessage()

"The specified string is not in the form required for an e-mail address."

Help!

Hi Carthalion,

If this is related to the book directly, you're better off posting this in its own forum located here: http://p2p.wrox.com/forum.asp?FORUM_ID=386

Regarding the error: I doubt this is the offending code. The MailMessage class has an empty constructor, so this line of code should compile just fine.

It looks like later code that sets an e-mail address (or the lack thereof) may cause the problem. Can you post the full code example? (Preferably in the book's forum with a reference to this post?)

Cheers,

Imar

Want to be my colleague? Then check out this post.

I am getting the same error message as stated above in C#. I have included the Code Behind file and the <system.net> section of the web.config file. Thank you for your assistance.

        myMessage.Subject = "Test Message";
        myMessage.Body = "Hello world, from Planet Wrox";

        myMessage.From = new MailAddress("[email protected]", "Brian Workinger");
        myMessage.To.Add(new MailAddress("[email protected]", "Brian Workinger"));
        Response.Write(myMessage);
        SmtpClient mySmtpClient = new SmtpClient();
        mySmtpClient.Send(myMessage);
    }
}

<system.net> from web.config file

<system.net>
        <mailSettings>
            <smtp deliveryMethod="Network" from="Brian Workinger &lt;[email protected]&gt;">
                <network host="smtp.Hotmail.com" userName="myUserID" password="myPassword"/>
            </smtp>
        </mailSettings>
    </system.net>
</configuration>

I'm thinking the problem is the 'from' value in the 'smtp' configuration. Have you tried it with just the email address?

Peter,

I removed my name from the From in the Smtp section and that did not help but I changed it as follows because I do think I had an error there, however, now I am getting a differnt error message. The modified code and error message are below.

smtp deliveryMethod="Network" from="Brian Workinger&lt;[email protected]&gt;">
                <network host="smtp.Hotmail.com" userName="myUserID" password="myPassword"/>
            </smtp>

and the following error message is returned.

The remote name could not be resolved: 'smtp.Hotmail.com'

That could certainly be a problem. Most system won't allow incoming SMTP mail drops without some authentication criteria being met. You are best off finding out what your ISP mail host is and try that. Usually an ISP will allow "anonymous" mail drops onto their server because it's coming from inside their network (even though you are on a public internet address, it's their address so they can control it). This is how I've done this type of thing. You just have to check your ISP web site for the SMTP settings.
