Handling Exceptions

Mind Games · April 30th, 2011, 08:47 AM

Hello,

I'm on chapter 18 page 661, and I'm trying to recreate an error with an invalid email address, it does not go to the 'yellow screen of death', it goes to my home page. My behind code is as follows:

Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net.Mail;
publicpartialclassDemos_ExceptionHandling : BasePage
{
protectedvoid Page_Load(object sender, EventArgs e)
{
MailMessage myMessage = newMailMessage();
myMessage.Subject = "Exception Handling Test";
myMessage.Body = "Test message body";
myMessage.From = newMailAddress("paulhudson2005.gmail.com");
myMessage.To.Add(newMailAddress("[email protected]"));
SmtpClient mySmtpClient = newSmtpClient();
mySmtpClient.Send(myMessage);
Message.Text = "Message sent";
}
}

What am I doing wrong?

Thanks in advance

Paul

Hi Paul,

Can you post the code for your web.config and Global.asax files? (Make sure to remove sensitive information from the config file first).

Also, when you post code, can you please past it in Notepad first? This forum doesn't like colored code for some reason...

Global.asax file:

I can't locate this file, is this an optional file you create?

Thanks

Could it be a permissions issue? You block access to all pages:

<location>
<system.web>
<authorization>
<deny users="?" />
</authorization>
</system.web>
</location>

What happens when you type the page's address in the address bar after you login?

The Global.asax file gets created a little later in this chapter; I didn't know where exactly, so I didn't realize you don't have it... ;-)
