IErrorHandler / catch(FaultException)

Posted By:      Posted Date: October 19, 2010    Points: 0   Category :WCF

I would like to be able to catch strongly typed WCF / .NET exceptions in my client code like so.






byte[] buff = null;

proxy.Ping(buff);  //Ping is decorated with appropriate fault contract for ArgumentNullException


catch(FaultException<ArgumentNullException ex)






I do not want to catch and rethrow exceptions as FaultException<T> in each service method (redundant and tedious).  Instead I am trying to do this using a custom IErrorHandler implementation like so:

void ProvideFault(Exception error, System.ServiceModel.Channels.MessageVersion version, ref System.ServiceModel.Channels.Message fault)


            if (error is ArgumentNullException)


                ArgumentNullException ane = error as ArgumentNullException;


                FaultException<ArgumentNullException> fe = new FaultException<ArgumentNu

SQL Server 2005 Try and Catch Exception Handling

I'm pretty excited to see that there is some real error handling for T-SQL code in SQL Server 2005. It's pretty painful to have your wonderfully architected .NET solution tainted by less-than-VBScript error handling for stored procedures in the database. The big difference being the addition of TRY..CATCH blocks. Let's take a look:

reader.getordinal("column_may_not_exist") how to catch the exception?



would any body please help me to catch the exception if the column doesnot exist as my table columns are not static.

sometimes its throwing me indexoutofrange exception as the column doesnot exist

thanks for the help guys

How to CATCH "Invalid postback or callback argument" exception?



How can I catch this exception? I do not want it to stop my page execution. Can/Should I do that?

Server Error in '/' Application.
Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

Using the BDC API how to catch the returned code when executing a stored procedure?

using BDC API, how can i catch the return code a stored procedure returns?

I tried Entity.Execute to execute a generic method. However, it returns an empty Entity table.

I know you can do it by setting up an output variable. I prefer returning an integer for tracking errors.

Any ideas?

Add Release-Only try-catch to CLR languages

Deploying a software, it's a common practice to encapsulate top-most function calls and/or event handlers with general try-catch blocks to deliver an error description to the user instead of just having him/her see the software exiting unexpectedly when unexpected exceptions occur. Unfortunately, during debugging it is most annoying to reach these log entries or message boxes instead of having Visual Studio halt where the exception occured. At the time of writing it is possible to designate particular exception types to halt the debugger when they are actually thrown. But it becomes a nuisance when there are many exception types to be marked this way. Plus, it becomes contra-productive if there is a scenario when expected exceptions of the marked types occur regularly and "Continue" has to be selected again and again in the debugger. Thus, I'd like to suggest to add a new, Microsoft specific, "try" keyword to all of the CLR languages (plus C++), perhaps something like "__try". This new kind of try should create a try-catch block only when compiling in Release mode. (This behaviour might apply to other configurations as well. I suppose the Configuration Settings dialog to provide an additional checkbox column to provide an option to select whether a particular configuration will create a try-catch block or not.)   See here for

Unable to catch WCF EndpointNotFound exception in SecurityToken.GetToken( . )

I have a set of WCF services that I am integrating with, I can not change them in any way because they are provided by a third party. I use a username/password scheme to authenticate with the services. If the services are not available I get an exception (EndPointNotFoundException) from the SecurityTokenProvider class that I can not catch. I understand why the exception is being thrown, I just need to know how I can handle it so that I can gracefully handle the errors in the user interface. Is there a way I can catch this exception or a better way to handle this scenario? The Exception The exception is thrown from System.IdentityModel.Selectors.SecurityTokenProvider : GetToken( TimeSpan timeout ) public SecurityToken GetToken(TimeSpan timeout) {    SecurityToken token = this.GetTokenCore(timeout);     if (token == null)    {        throw DiagnosticUtility.ExceptionUtility.ThrowHelperError(new SecurityTokenException(SR.GetString(SR.TokenProviderUnableToGetToken, this)));    }     return token;} The channel open part When I open the channel I have it wrapped in exception handling, but none of it seems to trap the SecurityToken exception. I am using the ExceptionHandlingProxyWrapperBase try{    this.Open();} catch( EndpointNotFoundException epnfe ){    // Handle the exception} catch( E

Catch Block question

What are the scenarios in which a t-sql catch block will not be called?   I have a SP which does partition management, sometimes i see that partitions have not been properly created... but still the catch block was never called. This is getting very hard to debug.   Can it be that in some timeout scenarios the catch block is not called?

FaultException : "The creator of this fault did not specify a reason" error

I have a simple service to return a custom SOAP Fault. And here is what the service throws MappingError me = new MappingError(); me.ErrorCode = ErrorType.OrderMappingFailed; me.Message = "Order mapping failed"; throw new FaultException<MappingError>(me); At this point i get an exception "The creator of this fault did not specify a reason". Looking around i see there is a FaultReason(String) class and  FaultException<> has a readonly Reason property. So, i used one of the overloaded constructor to set the FaultReason and made it work. Here is the working code MappingError me = new MappingError(); me.ErrorCode = ErrorType.OrderMappingFailed; me.Message = "Order mapping failed"; FaultException<MappingError> fe = new FaultException<MappingError>(me, new FaultReason("Order Guid is NULL")); throw fe; Now, will this be the behaviour when Winfx ships. If that be the case please update the FaultException<>  SDK docs. [ServiceContract] public interface IMyService { [OperationContract] [FaultContract(typeof(MappingError))] Guid SendRequest(int ID); }   [DataContract] public class MappingError { [DataMember] public ErrorType ErrorCode; [DataMember] public String Message; }

Is it possible for one thread to catch an event thrown by another thread?

I have a very simple class (shown below) that monitors the mouse position on a separate thread to see if it is hovering over the same spot for more than a second.  I have to do this because the Windows Forms control I am using is an interop COM component that does not have or implement the MouseHover event. Anyway, the class that instantiates asrMouseHover (lets call it WinFormMain) adds a handler for the asrMouseHover.MouseIsHovering event.  The problem is, when this event is raised and caught, the handler in WinFormMain is running on the same thread as asrMouseHover.  I need it to run on WinFormMain... hence, is it possible for one thread to catch an event thrown by another thread.    Public Class asrMouseHover Public Event MouseIsHovering(ByVal sender As Object, ByVal e As System.EventArgs) Private _timer As System.Threading.Timer Private _xCoord As Int32 = 0 Private _yCoord As Int32 = 0 Public ReadOnly Property XCoord() As Double Get Return _xCoord End Get End Property Public ReadOnly Property YCoord() As Double Get Return _yCoord End Get End Property Sub New() Dim myTimerCallback As System.Threading.TimerCallback = New TimerCallback(AddressOf MyCallbackMethod) _timer = New System.Threading.Timer(myTimerCallback, Nothing, 1000, 1000) End Sub Sub MyCallbackMethod(ByVal s
