There used to be an article at ELMAHs docs site that contained this information, but it seems to have been removed. I think it's as simple as setting a configuration setting in the section, but I haven't a clue what it isCan anyone take a few seconds and drop the configuration setting here?

I spawn a thread on Application_Start and would like to log exceptions. There is not Context/HttpContext/HttpContext.Current, so how might i get it to log?ATM it does not catch any exception in my threads and if i write ErrorSignal.FromCurrentContext().Raise(ex); i get an error about context cannot be null.Maybe i can create a dummy HttpContext but somehow i dont think that will work well.-edit- i tried ErrorSignal.Get(new HttpApplication()).Raise(ex); and it doesnt seem to pick up that exception.
View 2 RepliesIs there a way to globally handle exceptions in regular ASP.NET Web Service (asmx) using ELMAH like we do it in ASP.NET web site ?
View 2 RepliesI have been experiencing instances where a FormView update or insert event fails and should throw an exception, but doesn't. This seems top be related to my switch to Visual Studio 2010 Ultimate and .Net 4.0. Since the switch I have seen this problem several times. Is there something new in .Net or VS that I need to do or set to get the exceptions thrown? Other exceptions seem to work fine...it's just with FormView and SQLDataSource that I don't see them.The specific errors I don't see reported include misspelling a field name in the Select, Insert or Update commands in the SqlDataSource.
View 2 RepliesI'm building the standard 3-tier ASP.NET web application but I'm struggling as to where to do certain things - specifically handling exceptions.
I've tried to have a look around on the web for some examples but can't find any which go as far as a whole project showing how everything links together.
In my data-tier I'm connecting to SQL Server and doing some stuff. I know I need to catch exceptions that could be raised as a result but I'm not sure where to do it.
From what I've read I should be doing it in the UI tier but in that case I'm not sure how to ensure that the connection to the database is closed. Is anyone able to clarify how to do this? Also if anyone knows as to where I could find an example 3-tier web application that follows best practices that would be great too.
We have a asp.net application and want to implement logging. The first idea was to use the Application_Error method in the global.asax file.
The problem is that ASP.NET very often seem to throw exceptions internally that are not caused by the application and which seem not to interfer with the users normal workflow. For example we often get HTTPExceptions, UnauthorizedAccessExceptions and others caught in this method, although there is no real error in the application.
iam inserting record in three tables in a database, iam using begin trans , commit transaction and rollback,
i want to use throw method, if any value insert wrong, pls correct me, i want to throw the error and
its go to rollback

View 3 RepliesI have problem with Dynamic Controls in my Wizard Steps. In one of my Steps, I create a set of text boxes and checkboxes based on values from an XML document. Now, I initialise my dynamic controls using the OnInit method of the page, but at this stage there is no xml document until that step is reached, and of course I get null exception. How do I set my dynamic controls so it doesn't throw an null exception and be able to load any xml document when that step is reached?
View 1 RepliesI'm using the old 404-rewrite method on a certain site that is tied to IIS6 *. So if I enter [URL] it calls my error page like so [URL]
Except if I call the page with a fragment, like [URL] I get the same result as above. I can't find the fragment anywhere:
Request.Url
Request.Url.OriginalString
Request.UrlReferrer
Request.RawUrl
headers, server variables, etc
This has come up because I want to resolve paths created by AJAX to their server-side versions. Is there any way for me to retrieve the original path from my handler?
I have a schema which contains the ErrorCode and ErrorDescription.
When error is captured i need to create a new xml and throw it to the client with the error code and description captured from the client
I m having a datagrid and for client side events I m using Javascript. I have few other buttons in the same page.
when I click on datagrid and select, it is working fine. After that, if I click on any other button in the Page, It is directly going to global.asax and throwing exception.
If I click directly on other buttons, they are working fine. Once I click on Datagrid and try to click on other buttons, it is throwing that exception.
I would like to find a way to raise an exception if the Session is written to when in readonly mode. When EnableSessionState is set to "ReadOnly", values can still be put in Session, but the next request they will not be there. This seems somewhat dangerous.
One option is to create a helper class which we alway use to access session. However, this still leaves room for a developer to inadvertently use session directly, and fall into the "readonly" trap. Is there a way to create a CustomSessionStateDataStore that sits on top of the existing session code? I could not see an obvious way, and you can't inherit from System.Web.SessionState.SessionStateStoreData directly.
Is it possible to get the DropShadowExtender to throw a shadow on both sides of a Panel? I can get it on either left or right, but not that it is right behind the panel, giving the impression that the item is lifted slightly from the page.
If it can not be done with DropShadowExtender, is there another way to do this without actual background graphic?
I'm following this blog post about setting up ELMAH with MVC: [URL] I've only done part 1. Everything works correctly if I simply go to the Home controller, and then cause an error. I can view /elmah.axd as well, and my errors are logging in the database correctly.
However, I've added an area to my application named Admin. If I navigate to /Admin, I receive the following error:
System.MissingMethodException: No parameterless constructor defined for this object.
public override IController CreateController(RequestContext requestContext, string controllerName)
{
var controller = base.CreateController(requestContext, controllerName); //Error here
var c = controller as Controller;
I'm assuming this has something to do with my Area.
EDIT for jfar:
For instance, I have an Employees controller in my Admin area:
public class EmployeesController : Controller
{
private IEmployeesRepository employeesRepository;
public EmployeesController(IEmployeesRepository employeesRepository)
{
this.employeesRepository = employeesRepository;
}
//...
}
I am trying to setup elmah for asp.net 1.1 application.i have following entry in my web.config
<httpHandlers>
<add verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" />
</httpHandlers>
[code]...
I have ELMAH setup on my production server and it has done a fantastic job of letting me know about any niggles - as well as any creative SQL injection!I've decided to introduce URl Rewriting and went for http://www.urlrewriting.net/ in the end. It was nice and easy to setup and it's doing exactly what I want with the customer-facing site.The problem is ELMAH. Because I've set the urlrewritingnet node in my config like so:
<urlrewritingnet
rewriteOnlyVirtualUrls="true"
contextItemsPrefix="QueryString"

For a Table A defined in the DB like this:
A :{ id, selfId, name,} where selfId is a foreign key refered to Table A itself.
I generated the Entity automatically like this:
A :{ string id; A self; string name,} when i update the entity in gridview Edit/Update CommandField
i got the exception:
Object reference not set to an instance of an object. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code. Exception Details: System.NullReferenceException: Object reference not set to an instance of an object. Source Error:
[Code]....
Stack Trace:
[Code]....
I guess maybe this is caused by:
A is to be updated, and when the EntityDataSource construct the new A, the reference "self" is invalid at that moment. I do not want to modify my DB structure and do not want to lose the self reference, The event EntityDataSource_Updating is not triggered while the exception hit. so i can not access my entity at any time. Maybe the worst idea is deal the whole Update Procedure myself. However, is there any better workaround?
How to make the linq throw error, when not null columns are there in the table.
Why I am saying, it is. I tried to add to column in the table. Linq throwed error os some sort. I could not understand. it was like some innner table etc.
I had to resort to native sql, which showed the error, as the not null fields are there in the table.
I'm interested in using ELMAH but need to configure it programmatically. We have existing infrastructure for determining connection strings and the like, and can't code them into Web.Config.How do I go about using ELMAH in this case?
View 1 RepliesI'd like to configure ELMAH for an ASP.NET MVC site entirely in code. This includes registering the module, setting the logging provider and settings, and filtering exceptions.The only part I've managed to do so far is filter exceptions. Has anyone else figured out how to do this? I'd really like to avoid cluttering up my config file with settings that won't ever change.
View 2 RepliesI am using Elmah in one of our production deployments and would like to secure the module to the local network only and not expose it to the public. I am aware of the remote logging option that can be turned off and also asp.net authorization, however I am interested to know if there is any support in Elmah's configuration to bind to a secondary NIC/network card which only faces the internal network ?
