Large number of soft page faults when assigning a TJpegImage to a TBitmap
I have a Delphi 6 Pro application that processes incoming jpeg frames from a streaming video server. The code works but I recently noticed that it generates a huge number of soft page faults over time. After doing some investigation, the page faults appear to be coming from one particular graphics operation. Note, the uncompressed bit...

Enteprise Library Exception Handling for WCF Fault Contracts - CLIENT SIDE
I have a Windows Service which communicates with WCF services. The WCF services are all fault shielded and generate custom UserFaultContracts and ServiceFaultContracts. No problems there.

Android XMLRPC Fault Code
Hey, We have been using XMLRPC for android and it was working well until we got our hands dirty with Base64 encoding for byte[] (images) -- (we did base64_string.replace("/","$$") for transmission). We have tried undoing the changes and its looking like an XMLRPC error. We are getting the following error in the DDMS: 06-10 23:27:02.97...
Setting the detail field of a `FaultException` without object serialization
I'm trying to adapt a framework originally written for WSE to WCF. The framework sometimes throws SoapExceptions from deep in its bowels, which I would like to catch and transform into FaultException objects that the WCF framework will handle. In order for the existing clients of this framework to continue working, I need the <detail> f...

how to create and manage wcf service clients?
At first I treated them as any dependency passing them in the ctor to the class consuming the service: var serviceConsumer = new ServiceConsumer(new MailingServiceClient()) The problem was that once an exception was thrown from the service it entered a faulted state and would not reply to any requests, so re-initialization was due. F...

WCF general fault is encrypted where protection level is sign only
If a general fault is raised on my service endpoint the fault response is undesirably and unexpectedly encrypted.

How to exclude stacktrace from axis2 fault response
Hello experts! I have an Axis2 web service which throws different detail messages in the fault response to signal problems in the call. At some point, due to server errors (others than the ones treated by the web service), in the fault detail string I get the full stacktrace of what happened. I do not want the client to see the stack ...
FaultException.Detail coming back empty
I am trying to catch a given FaultException on a WCF client. I basically need to extract a inner description from the fault class so that I can then package it in another exception for the upper layers to do whatever. I've done this successfully a number of time, what makes it different this time is that fault is declared as an array, ...
