Why does Global.asax not react to this error?


I have a website that accepts payments via PayPal. Part of the PayPal process involves the PayPal server sending what is called an Instant Payment Notification (IPN) post to one of my web pages that is not normally seen by anyone. This IPN handler page is designed to process the IPN post and return data to the PayPal server for validation without any user involvement.

There was no particular need to do so, but I used my normal master page when creating the IPN handler page and a recent update to this master page has caused an HTTP error code 500 (Internal Server Error) only when the IPN handler page is activated. The code change was a patch I obtained from an online source to fix a page layout issue with the Safari browser. I don't understand the code (which is shown below) but it works for all my normal pages.

Two questions arise.

  1. Can anyone explain why the patch shown below fails in the particular situation of a page that is not actually being viewed in a browser?
  2. Secondly, and much more important, why did the error caused by this code not trigger a reaction from my Global.asax file, which is programmed to send me an email in the event of any error?

I only found out about the HTTP error code 500, and associated error details, by contacting m

Custom Error in Global.asax


Hai all,

Please give me an urgent help.

In my application I need a custom error mechanism. I tried the different custom error mechanism that we can set through the web config file and its working fine. But now I tried to implement the same mechanism through the application error function in the global.asax page.

The code is given below:-

void Application_Error(object sender, EventArgs e)


Exception exception = Server.GetLastError();

int httpCode=0;

if (exception.Message == "Access Denied")


//httpCode = 403; //if (!Response.IsRequestBeingRedirected) // Response.Redirect("~/ErrorPage.aspx");

Response.Redirect ("~/ErrorPage.aspx");

} else


HttpException httpException = (HttpException)exception;

httpCode = httpException.GetHttpCode();

switch (httpCode) {

case 404: Response.Redirect("~/InternalServerError_500.aspx?errorCode=404"); break;

//case 500: Response.Redirect("~/InternalServerError_500.aspx?errorCode=500"); break;

default: // Code tha

Windows 7, IIS 7.5 and VS2010: can't edit global.asax


Hey and thanks!


As the subject line notes the software in use, anyone have an idea why I can't edit global.asax in VS2010 (being ran with the 'run as administrator' advanced property check box checked)?  The file properties in explorer show local machine admins have full control (I am in that category) and also that IIS has windows auth enabled for the default web site.  What is this other level of security on here that I'm missing?  I can edit web.config, vb files and general aspx files with no problem--just the global.asax file causing a headache...





Returning custom error messages with an UserNamePasswordValidator

Ok, my head hurts from banging it against the wall. I'm new to WCF, I have searched for a solution for days, please help a desperate fellow programmer if you can :-( I have a WCF service hosted in IIS, I implemented a UserNamePasswordValidator, and it seems impossible to find a way to return a custom error message to the client when the user is not allowed in, this blows my mind. I have searched everywhere, many are asking the same question since 2006 and so far I haven't found an answer that works. If you are thinking of replying that it is not secure to return a custom error message to an unauthenticated client, please save yourself some time and don't do it. There are multiple enterprise business scenarios that this is required. Just in our organization an account could be locked out, in which case the user must be directed to the IT department to get it unlocked, it could be that the credentials are correct but the user hasn't paid their fees in which case they must be directed to the appropriate department, or it could even be that the user tried to access the service during a time of the day in which the service is not available. From searching around, I have tried doing the things below in the Validate method, however the client always receives a MessageSecurityException, which contains none of the custom messages that were originally thrown, neither in the object,

custom 401/login failure error messages

I have a req to display a custom error message when a user fails to log in 3 times.  The default behavior seem to be for a redirect to something like this http://server/_layouts/AccessDenied.aspx?loginasanotheruser=true&Source=http%3A%2F%2Fserver2k7%2FPages%2FDefault%2Easpx after the third login attempt.  The resulting page just comes up as blank...I'm guessing because it failed auth.  My initial thoughts were to create a custom error page, and redirect with an http module.  That solution (while it does redirect) puts me right back to the initial problem of just a blank page being displayed after the failed auth.  I've been struggling with this for a while now, ANY thoughts or advice would be greaty appreciated.  Is it even possible? 

Best practice for user defined error messages in SQL Server 2005/2008 --Need help

My requirement is to setup a standard practice for our team in handling DB erros and also  user defined messages. We are handling exceptions using Raiseerror method with in Try and Catch blocks.  For user defined message, we are using Sp_addmessage to add our application specific error/warning messages with error codess>80000.  Ex: 80001 | Company name already exists. please check.

Stuck during restore process, no error messages

I need to restore a solution (a webpart) from a Sharepoint 2010 backup to another Sharepoint 2010 installation on another server. In CA and exactly in the page _admin/BackupStatus.aspx I see that: A backup or restore is currently in progress. There are no current or recent backup or restore processes to show. If you recently started a backup or restore process, you may need to refresh this page after several minutes for it to appear. Hours have passed since I started the restore process In _admin/ServiceRunningJobs.aspx there is no backup/restore job running. The question is: What can I do to try again a restore if I cannot stop the restore that is "running"? Please Help.  

Function in Global.asax is not running

Hi, I am using a Global.asax in on my webpage to run a function with an interval. In this test I have set the interval to 1 minute to be able to see what happens. I have declared a timer in the Application Start which should mean that when I open up the webpage after I have uploaded the Global.asax the timer will start.   However with this code below where I try to create a file named newFile.txt, this file is not created. I cant really understand what I could be missing. It seems that the function is not running ?<%@ Application Language="C#" %> <%@ Import Namespace="System" %> <%@ Import Namespace="System.Collections.Generic" %> <%@ Import Namespace="System.Linq" %> <%@ Import Namespace="System.Web" %> <%@ Import Namespace="System.Web.UI" %> <%@ Import Namespace="System.Web.UI.WebControls" %> <%@ Import Namespace="System.Drawing" %> <%@ Import Namespace="System.Net.Mail" %> <%@ Import Namespace="System.Net" %> <%@ Import Namespace="System.Threading" %> <%@ Import Namespace="System.IO" %> <%@ Import Namespace="System.Text" %> <%@ Import Namespace="Microsoft.Win32" %> <%@ Import Namespace="System.Reflection" %> <%@ Impo

Error handling, multiple error messages

Hi all. Have you noticed that sql server catches only last error message? Try to run this: exec('create table #t ( t1 timestamp not null default 0 )') You get: Msg 1755, Level 16, State 0, Line 1 Defaults cannot be created on columns of data type timestamp. Table '#t', column 't1'. Msg 1750, Level 16, State 0, Line 1 Could not create constraint. See previous errors. Now try to run the same thing in try catch: begin try exec('create table #t ( t1 timestamp not null default 0 )') end try begin catch declare @Error varchar(max) set @Error = error_message() raiserror(@Error, 16, 1) end catch The error message this time is: Msg 50000, Level 16, State 1, Line 10 Could not create constraint. See previous errors. Does anyone have any better ideas how to handle sql server errors? Thanks

Application level event without global.asax

I have a need to add an application level event (like Application_Start) but not in global.asax.  The reason that I can't use global.asax is because this is a web application for which I don't have source code but I want to add some functionality to it.  I need to insert an application start code and was wondering it there was anyway to do it.  I'm not sure that if I add a class or aspx page to the sie if it will dynamically compile since this is a web application.  I know this is a crazy request but let me know what you think.Also, this web site was written in .NET 2.0.Thanks.
