WCF Fault Exceptions With Silverlight?
Apr 1, 2011
I have a set of WCF services which I have been using with an ASP.NET MVC application so far. These service operations return a FaultException when the server has identified problem with what the client has submitted. For example:
[code]...
However with Silverlight this all fails. The server returns a 500 status code with the faultexception (as expected) but to Silverlight this just looks like a duff response.
The following MS article indicates a (ugly) work around for this: [URL] This workaround makes the service transmit 200 status codes, even if there is a FaultException, so that the Silverlight client can get them. But this will mess up 'normal' clients of my service (my ASP.NET application, other users in the wild).
However, the point of services is to have seperation from your clients. I still want my services to return 500 status codes so that my ASP.NET application can detect the FaultExceptions and handle them. But I also want Silverlight to be able to handle them too.

I'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.

I'm having some trouble with references to an external project that contains services for my application.After changing the types of some properties in a class, I got errors like "Method not found: get_Size() (Where Size is the name of the field)
Method not found: 'Ropes.Services.Contracts.Data.SearchResultPage`1 Ropes.Services.Business.Experience.ExperienceFactory.Search(Ropes.Services.Business.Search.SearchRequest)'.

I use HttpRequest, when there is a SOAP fault, I get 500 error. I read that you can get the SOAP fault info in the response stream, but when there is a 500 error, how do you get the response stream?

I have a Client Application calling a WCF service. I was getting a faultedState error on the client, after looking around I discovered this was because the client proxy was in a using statement and was actually hiding a security error. I have not been able to fix this fault and have not been able to find much online about it. I have undone the changes that caused this error to happen and the error continued, I have even went back to a different version of the solution and still encountered this error. I later set up my solution on another machine and pretty much encountered the same problem after working for a couple of hours.
I have the service and client running in my local solution. I'm using visual studio 2008. The error I get is "An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail." and inner exception is "An error occurred when verifying security for the message."

While i was writing a piece of code in C# using ASP.NET i needed to create a message queue to store fault messages. However, I couldn't find the System.Messaging namespace in the namespace library in Visual Studio 2010. Does anyone know how can I use message queuing now?

ASP.Net 2.0 Web Services automatically create both SOAP 1.1 and SOAP 1.2 bindings. Our web service, however, has SOAP extensions and custom exception handling that make the assumption that only the SOAP 1.1 binding is used (for example, the SOAP extension uses the HTTP SOAPAction header to control behavior).
I am looking to correct the code that makes these assumptions and make it work with either SOAP 1.1 or SOAP 1.2 properly. I am running into a bit of a problem in the generation of elements for our SOAP faults.
Consider the following web method implementation:
[Code]....
The SOAP 1.2 response now has the wrong qualified name for the detail element. It should be <soap:Detail>, but instead is merely <detail>, same as the SOAP 1.1 response.
It seems that the ASP.Net 2.0 framework has done quite a bit to transform a SOAPException into the appropriate form for the SOAP version, but neglected to properly handle the detail element. Additionally, they don't seem to have exposed the correct SOAP 1.2 qualified name for the detail element as was done with the SoapException.DetailElementName property.
So, what is the correct way to add a detail element to a SOAP fault response that works for both SOAP 1.1 and SOAP 1.2? Do I need to detect the SOAP version myself and hard-code the SOAP 1.2 qualified name for the detail element?

How should I log exceptions? I never tried logging in .NET before. Nor try to dump exceptions to a txt (or binary) file. I dont require a text file, just a way to view the logs with the file and line #.

string lNewHTML = Regex.Replace(lOldHTML, "(word1|word2|word3)", "<a href="page.aspx#$1">$1</a>", RegexOptions.IgnoreCase);
The code works, but I need to include some exceptions to the replace - e.g. I will not replace anything i an img-, li- and a-tag (including link-text and attributes like href and title) but still allow replacements in p-, td- and div-tags.

How can we prevent page crash in asp.net? Is there any generic function or place like global.asax where we specify a file to redirect to when an unhanded exception occurs? (like we redirect to a specified page when 404 page not found exception occurs?

I need to handle 404 exceptions differently than all other types of them. What is the best way to identify those 404 exceptions (distinguish them from other exceptions)?
The problem is that there is no a special exception class for 404 errors, I get regular System.Web.HttpException with Message = "File does not exist."
Should I just use exception's message for it or is there a better way?

"I DONOT WANT TO use the default error page tachnique, because i donot want the webpage to redirect!"
yes there is the try and catch
yes there are way to add exception handling mathods overwrite for controls
but what i need is,
it may just be a simple sql command,it may be a control such as formview, it may be a control such as datagrid, whatever it may be, when an illegal entry is done into the table of the database,
"THE BIG ERROR PAGE SHOULD NOT COME!!"
instead
a label at the top of the same page (where the illegal operation is performed) should display the error like
"error caused by "this control" and the error message is "null is not allowed in this field blah blah"

I put some global error handling in place, but am having problems testing it by causing unhandled exceptions.
Here's all I can think of at the moment. feel free to add to this list with more ways to trip unhanndled exceptions.
1) Dangerous form data - Entering characters such as < and > in a text box and trying to submit
2) Put invalid values in a URL parameter - eg if you page is www.test.com/home?testid=XXX where XXX is the form number/identity # you are trying to pull up, put a number that doesn't exist in the URL and hit enter.
I'm sure I could change some stored procedures or otherwise mess with my data access components but I'd rather not have to change any code anywhere...I want to be able to generate these exceptions on the front end, like a user would.

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.

If you wrap a call to HttpResponse.End within a try catch block, the ThreadAbortException would automatically be re-raised. I assume this is the case even if you wrap the try catch block in a try catch block.How can I accomplish the same thing? I do not have a real-world application for this.

I am making MSSQL stored procedure CLR calls from ASP pages. When an exception occurs, it is logged and then rethrown. In this scenario I need to be able to handle the exception (if possible) in the ASP page. Note that I cannot move away from classic ASP in this instance; I am stuck within a legacy system for this project. let me know if you know of a way to handle the exceptions in classic ASP.
