Hi Imar. Im on page 532,chapter 15. At step 5 it says now save your changes and request signup.aspx. Unfortunately i get the following error:

The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Must issue a STARTTLS command first
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

My <smtp> does contain a valid email address. I mean i had everything working in chapter 9 with regards to email.

It does say in the book however that if your server requires you to use SSL i may habe a problem as i cannot set the EnableSSL property direcetly.
Is that the problem here??

Do i have to write code in the sendingMail event do you think thats what the problem is? If so could you give me an example of the code id need to write here. If that isnt the problem please let me know what you think is.

signup.aspx code:

Code:

<%@ Page Language="C#" MasterPageFile="~/MasterPages/MasterPage.master" AutoEventWireup="true" CodeFile="Sign-up.aspx.cs" Inherits="Sign_up" Title="Sign-Up" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
    <asp:CreateUserWizard ID="CreateUserWizard1" runat="server">
        <MailDefinition BodyFileName="~/App_Data/Sign-UpConfirmation.txt" 
            Subject="Your new account at Salford Student Books">
        </MailDefinition>
        <WizardSteps>
            <asp:CreateUserWizardStep runat="server" />
            <asp:CompleteWizardStep runat="server" />
        </WizardSteps>
    </asp:CreateUserWizard>
</asp:Content>

By the way i am aware ive called the page sign-up rather than signup. Was just a preference.

Many thanks for any help.

Hi there,

The controls send their own mail messages and don't take the SSL settings into account. There are two solutions:

1. Upgrade your site to .NET 4 which enables you to configure SSL in the web.config

2. http://imar.spaanjaars.com/505/using...at-require-ssl

Hope this helps.

Cheers,

Imar

Hi Imar. How would i go about upgrading my site to 4.0? Could this have any negative repurcussions for messing the site up ive created for if its difficult to upgrade to 4.0.

I attempted your step 2 and followed your link. I tried using this code in the sending mail method:

Code:

protected void CreateUserWizard1_SendingMail(object sender, MailMessageEventArgs e)
{
  SmtpClient mySmtpClient = new SmtpClient();
  mySmtpClient.EnableSsl = true;
  mySmtpClient.Send(e.Message);
  e.Cancel = true;
}

I also attempted as per the recommendations on p.532 step 5 to use the same code that is used in the contactform.ascx. That didnt work either.

Here is the error im getting:
Server Error in '/' Application.
--------------------------------------------------------------------------------

    }
   
    protected void CreateUserWizard1_SendingMail(object sender, MailMessageEventArgs e)
    {
        SmtpClient mySmtpClient = new SmtpClient();
        mySmtpClient.EnableSsl = true;
        mySmtpClient.Send(e.Message);
        e.Cancel = true;

        
    }
   
}

Any help or advice on how to get past this step 5 on page 532 would be appreciated.

The error message is staring you in the face:

Quote:

The type or namespace name 'SmtpClient' could not be found (are you missing a using directive or an assembly reference?)

You need to add a using statement for the System.Net.Mail namespace as explained on page 324, step 3.

Are you using me as your on-line debugger? ;-)

You'll get better and faster results if you know how to interpret error messages. Take a look at this:

Isn't that exactly telling you what the problem is?

No im just completely new to programming hence buying your book. This is the first time ive had a go at making a site so error messages are pretty hard to decipher for someone like me. Ive added a using directive and am unsure what it means or requires me to do by telling me there is no definition or extension method accepting an argument of type ASP.sign_upaspx

Hopefully this will come with experiencing of seeing the same error messages come up.

I understand that. But in order to succeed, you need to figure out a way to understand and interpret the error message so you can take action on them. .NET's error messages are typically very detailed, and together with the information from my book, I hope you can figure out what most of them mean. In this case, it's literally telling you what the problem is. In cases like this, this is what I do:

1. I read / Interpret the error. In this case, it's telling you that some code is expecting the presence of a CreateUserWizard1_CreatedUser method.

2. I copy and paste that name to the clipboard and paste it in the Find dialog of Visual Studio. For now, the current document will do, but for other issues you may want to search the entire site.

You'll quickly find this markup:

Code:

 
 <asp:CreateUserWizard ID="CreateUserWizard1" runat="server" 
    oncreateduser="CreateUserWizard1_CreatedUser" 
    onsendingmail="CreateUserWizard1_SendingMail">

This says something like: "If the CreateUserWizard is ready creating the user, then execute the CreateUserWizard1_CreatedUser method".Obviously, in order to execute a custom method like this, it needs to exist. It doesn't exist in your page, and thus you get the error.

Two ways to fix it:

1. If you don't need this method, simply remove the entire OnCreatedUser attribute and its value from the control. No attempt will then be made to call a method when the user is created.

2. If you do need it, create the method by double-clicking it in the Events category of the Properties Grid for the CreateUserWizard control as explained in the book.

Hope this helps,

Imar

Thanks for explaining in detail what the error message actually meant. Ive removed the onCreatedUser element and got it to successfully work.

Many thanks.
