Website Error Reporter in ASP.NET

Now, follow the steps (described in video) to create such Web application.

Step1

Create Web Application by navigating File > New > Project > ASP.NET Web Application.

Step2

Open the Global.asax file and type following coding in Application_Error.

void Application_Error(object sender, EventArgs e)

{

// Code that runs when an unhandled error occurs

Response.Write("<h2>Error Page</h2>");

// Get the exception details

Exception exc = Server.GetLastError();

Response.Write("Sorry for the inconvenience that may have been caused to you.");

Response.Write("<b>Error Message</b><p>" + exc.Message + "</p><br>");

// Clear the error from the server

Server.ClearError();

// Report to Administrator

string url = HttpContext.Current.Request.Url.AbsoluteUri;

string MailBody = "Website user is getting bad experience on you website. Find the details below:<br><br>";

MailBody = MailBody + "<br><br><b>Error on Page (Target Webpage): </b>" + url;

MailBody = MailBody + "<br><br><b>Link on Webpage (Source Webpage): </b>" + Request.UrlReferrer;

MailBody = MailBody + "<br><br><b>Error Message: </b>" + exc.Message;

MailBody = MailBody + "<br><br><b>Trace Message: </b>" + exc.StackTrace;

// Other browser based stuffs

MailBody = MailBody + "<br><br><b>Platform: </b>" + Request.Browser.Platform;

MailBody = MailBody + "<br><br><b>Browser: </b>" + Request.Browser.Browser;

MailBody = MailBody + "<br><br><b>Browser Type: </b>" + Request.Browser.Type;

MailBody = MailBody + "<br><br><b>Browser Version: </b>" + Request.Browser.Version;

string MailResponse = sendmail("[email protected]", "Bad Experience", MailBody);

Response.Write("<br><br><b>Note: </b>" + MailResponse.ToString());

}

Step3

Create a new method in Global.asax file for sendmail method as given in above code. Here is the method code:

private string sendmail(string ToEmailAdd, string MailSubject, string MailMessageHTMLString)

{

System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();

message.To.Add(new System.Net.Mail.MailAddress(ToEmailAdd));

message.From = new System.Net.Mail.MailAddress("[email protected]", "ITORIAN.COM");

message.Subject = MailSubject;

message.Body = MailMessageHTMLString;

message.IsBodyHtml = true;

System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient();

client.Port = 25;

client.Host = "mail.itorian.com";

System.Net.NetworkCredential nc = new System.Net.NetworkCredential("[email protected]", "*****");

client.UseDefaultCredentials = false;

client.Credentials = nc;

try

{

client.Send(message);

return "Automated System success to report this to the Administrator.";

}

catch

{

return "Automated System not success to report this to the Administrator.";

}

}

Step4

Now open the Site.Master and create any broken link or any other runtime mistake and then run the project.

Step5

Type to navigate by clicking broken link, it will display the error message instead of displaying the red page error and also sends the email to you inbox containing full error description in body.
