Ive been doing some reading on this topic, http://forums.asp.net/p/1029088/1408275.aspx, and http://www.aspcode.net/Requiring-email-verification-for-new-accounts.aspx, but I cant seem to figure out how to send emails to verify email accounts when creating a new account.

My code looks like:

           protected void CreateUserWizard1_CreatedUser(object sender, EventArgs e)
    {
        //Send email to user for verifying account
        CreateUserWizard cuw = (CreateUserWizard)sender;
        MembershipUser user = Membership.GetUser(cuw.UserName);
        Guid userId = (Guid)user.ProviderUserKey;
        System.Net.Mail.MailMessage EmailMsg = new System.Net.Mail.MailMessage("info@ask.com", CreateUserWizard1.Email);
        EmailMsg.Subject = "Email Verification from ask.com";
        EmailMsg.IsBodyHtml = true;
        EmailMsg.Body = "Thanks for registering with www.ask.com!<br /><br />Your activation link : <a href=http://www.ask.com/activate.aspx?ID=" + userId.ToString() + ">Link</a>.";
        System.Net.Mail.SmtpClient mailClient = new System.Net.Mail.SmtpClient();
        //This object stores the authentication values
        System.Net.NetworkCredential basicAuthenticationInfo = new System.Net.NetworkCredential("smtpserverinfo", "smtpserverpassword");

        mailClient.Host = "mail.ask.com";
        mailClient.UseDefaultCredentials = false;
        mailClient.Credentials = basicAuthenticationInfo;
        mailClient.Send(EmailMsg);
       

    }

and in activate.aspx:

     protected void Page_Load(object sender, EventArgs e)
    {
        Guid oGuid = new Guid();
        MembershipUser oUser = Membership.GetUser(oGuid);
        if (oUser != null && oUser.IsApproved == false)
        {
            oUser.IsApproved = true;
            Membership.UpdateUser(oUser);
            System.Web.Security.FormsAuthentication.RedirectFromLoginPage(oUser.UserName, false);
        }
    }

 the problem is that when I click on the link it generates with the user id in the URL, it throws this error:

Server Error in '/' Application.

Runtime Error

<!-- Web.Config Configuration File -->

    <system.web>

<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>

 nope.

Then try tweaking your web.config file.  I have run into this issue several times and sometimes I toggle the customErrors value a couple of times between RemoteOnly and Off and it tends to start working.  Otherwise, verify that this is set as an application in IIS and then you don't have any other web.config files that might be conflicting with it.

Have you successfully sent an email through mail.ask.com prior to this? 

the email's job is to create the link to the activation page and send it, right?

now, assuming that was successful, which i cannot test until i upload to server and thats another issue... but, my problem is that, even when I generate the link myself, and enter it in the URL, it fails. am i misunderstanding how this works? cause im thinking that the first part only generates a URL, and once that URL is clicked, then the activation should occur, no?

caligali:

     protected void CreateUserWizard1_CreatedUser(object sender, EventArgs e)
    {
        EmailMsg.Body = "Thanks for registering with www.ask.com!<br /><br />Your activation link : <a href=http://www.ask.com/activate.aspx?ID=" + userId.ToString() + ">Link</a>.";        
    }

 

and in activate.aspx:

     protected void Page_Load(object sender, EventArgs e)
    {
        Guid oGuid = new Guid();
        MembershipUser oUser = Membership.GetUser(oGuid);
        if (oUser != null && oUser.IsApproved == false)
        {
            oUser.IsApproved = true;
            Membership.UpdateUser(oUser);

Hi

Base on my understanding, you want to approve user in activate.aspx, I suppose it's http://www.ask.com/activate.aspx?ID=1234567

So you need to retrieve the userid from queryString like Request.QueryString["ID"], right?

It seems that you are looking for user with empty guid.

I had a few errors.

My email creates a link to the page: http://www.myApplication.com/activate.aspx?ID=21c46d2d-76cf-446b-847c-efe0758f4975

But, since Im running the code on my localhost, www.myApplication wont do me any good. I had to change it to http://localhost:56300/myApplication/activate.aspx?ID=21c46d2d-76cf-446b-847c-efe0758f4975 so at least now it tries to run the code in activate.aspx

Then, in activate.aspx, like XiaoYong Dai said, I had to pass the query string to the Guid:         Guid oGuid = new Guid(Request.QueryString["ID"]);
and that did it. Thanks a lot!
