Configuration :: Error Handling Strategy For Exceptions Causing Page Request Fail?
Nov 1, 2010
I have been tasked with implementing a strategy to catch all errors in an ASP.net application which cause a user request or interaction to crash and then e-mailk this exception to a support team in advance of a user calling about the error.Some errors however are not causing the page to crash or be redirected to the custom error page but these are being emailed to the support team instead of simply being loggedMy requirement is to seperate what exception types will cause a page fail and which will not.Example I am currently receiving a System.Web.HttpUnHandledException which is not causing any page to fall over and therefore is not of relevance to the support team. this can be logged but does not require emailing.

I have what is probably a basic question, but I am rather new to writing exception handling code. I thought I understood the concept, but apparently I don't, heres the code:
[Code]....
If I enter in any non-integer values, the textbox is set to nothing and the label displays the error message. However, now that I have verified the textbox contains an integer, I want to continue on and use that value. The remaining code works fine unless there was an exception, in which case the conversion to an int value for x throws an error.
All the examples I have looked at demos the structure of try-catch-finally, but in this instance I am not performing any clean up, I want to execute code when a valid value is entered into the textbox.

I have a typical scenario that I'm struggling with from a performance standpoint. The user selects a value from a dropdown and clicks a button. A stored procedure takes that value as an input parameter, executes, and returns the results to a grid. For just one of the values ('All'), the query runs for roughly 2.5 minutes. For the rest of the values the query runs less than 1ms.
Obviously, having the user wait for 2.5 minutes just isn't going to fly. So, what are some typical strategies to handle this? Some of my own thoughts:New table that stores the information for the 'All' value and is generated nightlyCache the data on the caching server

I think ive narrowed down my problem, I have a form but the "submit" buttons are being handled by Javascript - since i need to build arrays manually outside of the model for processing
[Code]....
I'm calling the Controller Action "Update" and passing it to string Arrays, when its finished - i want it to redirect to another action - it doesnt.
[Code]....
I just really wanna construct those arrays, and pass them to a controller...i think the ajax is waiting on a result and ignoring the redirect.

We have created a new cname for our subdomain website. The new website is working properly with cname. We do have .net application inside the webiste which is not working with cname. For eg,1. http://servername/_folder1/app/mypage.aspx (Accessing .net application (App) website without cname)2. http://NewDomian.xxxx/app/mypage.aspx (Accessing .net application (App) website with cname)The first case is working perfectly, but when I access the second url, I got the following error.Description:

Our application has a database varchar field which at times store datetime values. Code is not formatting the date time values before storing.
Now the issue is coming when we are trying to restore database from our deployment server
to local server and then run the application.Dates are getting stored in format 'dd/mm/yyyy' [ex 31/12/2009] on deployment machine [EN-UK]however when we have restored DB and then try to run application on local server it throws invalid datetime exception, probably because it is expecting
datetime in 'mm/dd/yyyy' format [EN-US] (Dont know why !!).
The code base for our ASP.NET application is deployed into server machines with Regional and local settings as English-UK. However our local servers have regional settings as English-US we changed the regional settings from Control Panel to En-UK however still same error is coming !!

When a server error occurs for whatever reasons (YSOD), the server will send a message via SMTP class. In my case, my company employs microsoft exchange and uses NTLM authentication for all domain users. I am authenticating users via NTLA windows integrated authentication. My question is, is it possible to utilize this authentication data, and pass it to the system.web SMTP username/password authentication scheme to send an email to me (the web developer) when the error occurs? I am pretty sure my company requires a username/pwd to send emails via SMPT on the ms exchange server.

What's the best way to handle exceptions that happen from within a controller's constructor?
All I can think of to do is use Application_OnError() or put a try/catch in my ControllerFactory.
Neither of these solutions seem ideal. Application_OnError is to broad - I have some non-mvc content in the site that has its own error handling. Using a try/catch block seems kinda hacky.
If I'm serving different content type -html/text/json/rss.... I would like to be able to handle the exception from within the action method instead of having to write all kinds of conditions to determine what kind of error message to serve.

I use Custom errors in my web.config. It works for urls like www.x.com/x.aspx , but when I write something like :
www.x.com/name (I have Application_BeginRequest dealing with it on global.asax) on the live server, IIS bypasses my application and shows its own error page.
How can I disable IIS error handling and redirect where I want to?

The default behavior of a [WebMethod] attributed static method on an aspx page is to return the error to the caller. We are accessing these methods using json, and the only way we have found of capturing exceptions is either a try/catch in every webmethod on the site or using a javascript callback with the error (which has the unacceptable downside of exposing the error to the client).
Is there any way to globally handle these exceptions using the HealthMonitoring setup in ASP.NET?

I have introduced site wide exception handling on my site to catch unexpected errors. The event handler sends a message to me when such an exception occurs. But the problem is that any clicks on my site will cause an exception to be thrown with the message: "This is an invalid webresource request."
I googled for an answer and only found a couple of references to 1. setting a fixed machinekey (which for some reason didn't work for me, I got an error saying that the virtual directory wasn't set in IIS, and as far as I know I'm not using IIS at all, I'm using the local development environment and then deploy to a web host) or 2. using a robots.txt file to stop robots from accessing the axd files, but that doesn't help either because it's not robots that cause the problem, anyone clicking around on the page will cause this error. how to solve this problem properly? For now I have handled it by catching and ignoring this particular error by the text in the error message, which works but I would rather fix it so that this error doesn't occur at all.

I have error handling in Application_Error event of globals.asax file. Inside this event, I'm using Response.Redirect(~errorview.aspx) method, for redirection to site which is able to handle errors in user friendly way.
Everything works fine, unless exception is rising in Application_Start event. When error occurs there, my application gets trapped in infinite loop with the Application_Error method hit repeatedly. What is more, the page I'm redirecting to never gets hit. Changing Response.Redirect(~errorview.aspx) method to Response.Redirect(~errorview.aspx, false) changes nothing.
The good news is, when Response.Redirect(~errorview.aspx) has been replaced with Server.Transfer(~errorview.aspx), errorview.aspx page succesfully gets hit.
The side effect now is not loading CSS, and errorview.aspx page looks ugly. What is more, the CSS is not loaded only when exception occurs in Application_Start event. Exceptions thrown from any other place don't make the CSS mess.
How I can handle this problem in correct way, and why the CSS is missing in the one particular situation ? What is the appropriate way of handling errors in my case ?
UPDATE
For CSS loading, I'm using this:
<link href="~/Css/Layout/style.css" type="text/css" rel="stylesheet"
runat="server" ID="_uid" />
error page I'm transfering from: http://localhost/APP/Pages/Module/Pages/ErrorView.aspx
css folder path: http://localhost/APP/Pages/Module/CSS/Layout/style.css

Is it at all possible to inject a request into IIS for a page, have IIS and ASP.Net handle it as normal, but get the response as html handed back to me programmatically?
Yes, I know that I could connect to port 80 using WebRequest and WebResponse, but that becomes difficult if you are accessing the IIS server from the same physical machine (loopback security controls et al).
Basically, I want to inject the request (eg for [URL]) between the points at which IIS would normally talk to the browser, and the point at which it would route it to the correct ASP.Net application, and get a response back from IIS between the points at which ASP.Net/IIS applies the httpfilters and hands the html back to the browser.
I'm predominantly working with IIS7 so if there is a solution that works just for IIS7 then thats not an issue.

Summary: DataAnnotation's automatic handling of an "int?" is making me rethink using them at all.Maybe I'm missing something and an easy fix but I can't get DataAnnotations to cooperate. I have a public property with my own custom validation attribute:
[MustBeNumeric(ErrorMessage = "Must be a number")]
public int? Weight { get; set; }
The point of the custom validation attribute is do a quick check to see if the input is numeric and display an appropriate error message. The problem is that when DataAnnotations tries to bind a string to the int? is automatically doesn't validate and displays a "The value 'asdf' is not valid for Weight."For the life of me I can't get DataAnnotations to stop handling that so I can take care of it in my custom attribute.This seems like it would be a popular scenario (to validate that the input in numeric) and I'm guessing there's an easy solution but I didn't find it anywhere.

I have custom errors set in the web config file as follows:
<customErrors mode="RemoteOnly" defaultRedirect="GenericError.aspx" />
Fine and dandy... I like that mode="RemoteOnly" facilitates development...
For unhandled exceptions, I have in global.asax:
Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
Response.Redirect("GenericError.aspx")
End Sub
However, unhandled exceptions are going to the generic error page instead of the informative yellow screen of death preferred by developers. I can comment out the redirect in global.asax, but then I need to remember to change it for the production environment. Is there a way I can check in Application_Error whether I am remote or not to determine whether to redirect?

Using vb.net/asp.net 2005. in the global.asax page in the application error page I am getting the exception information as follows:
[Code]....
To find out when there are any exceptions when users are using the system, then the ErrorDetails are being auto-emailed to members on the IT team to help in troubleshooting. The problem is this: I want to find out what page is the user is on when the exception happens, sometimes the stacktrace does not list the aspx page. Does anyone know how to get this information?

So on my master page I would have the following this is where the content goes So when I would submit a content page, placeholder named "ErrorPlaceHolder" would be found and error would be displayed in the pages "Pre Render" event..I guess. How would I do that?
