Silverlight: How to Communicate with Desktop Application via HTTP

IntroductionThis article is a free continuation of How to Receive Messages from a Desktop Application and How to Send Message to a Desktop Application where the Silverlight application communicates with the standalone .NET application via TCP. In this article, I would like to show how to implement the communication via HTTP. The example below implements a .NET application as a service and a

Android Fundamentals: Working With Content Providers

The TutList application that we’ve been working with has a pretty big flaw right now: the article data is not “live”, but static content. In this tutorial, you take several more steps towards a flexible and expandable solution by modifying the application to act as a data-backed content provider. The Android framework uses a concept called content providers to enable applications to share and use

WCF ExceptionHandling in Silverlight

I have recently done some LOB application development in Silveright in which we used a WCF service to communicate to the backend. There was an unexpected surprise that Exceptions throw in the WCF service were not transferred to the Silverlight Client! In Silverlight you always get a System.ServiceModel.CommunicationException: The remote server returned an error: NotFound.... error. We wanted to

Getting something better than “Server not found.” from WCF in Silverlight

When developing applications in Silverlight it is inevitable that you will need to perform a request back to the server for data or processing. The common practice is to use Windows Communication Foundation (WCF). I find that WCF usually handles all of my needs and it works well when everything is happy and just right. However, if anything is not in its correct place, we can have tons of problems

HttpContext.Current returning null when using NetTcpBinding in WCF4

When using NetTcpBinding, not all of the features of WCF are available, particularly those using HTTP. NetTcpBinding removes a dependency on HTTP (and IIS as a result, allowing the service to be hosted in WAS instead.) HttpContext.Current is one of the features in WCF that is not available when using NetTcpBinding.Read more: WF, WCF, and AppFabric notes Posted via email from Jasper-net

Memcached for Dummies

The other day I was chatting with a colleague about Memcached.  Eviction policy came up, and I casually mentioned that Memcache isn't strictly LRU.  But a quick Bing search said Memcache is LRU, like this Wikipedia entry.  Hmm, I was 99.9% sure Memcache is not LRU, something to do with how it manages memory, but maybe I was wrong all these years.  After reading through some Danga mailing lists

10 Steps to Initiating an OpenStack Cloud Service

OpenStack currently consists of three main components: Nova (Compute), Swift (Object Storage), and Glance (Image Service). There are some other projects such as a dashboard and mobile apps as well.

I’d like to talk about the

Microsoft clarifies HTML5 v Silverlight

Microsoft has learned its lesson and, not wanting to alienate or spook its Silverlight developers yet again, has posted a carefully crafted blog post that explains its position vis-a-vis Sliverlight and HTML5.  Only a short time ago Microsoft upset a lot of developers by claiming that HTML5 was the way of the future, a fine sentiment, and that Silverlight was only for Windows Phone 7 - not such

HTML vs. Silverlight vs. WPF

At Readify we focus on the Microsoft stack - WPF, Silverlight, and ASP.NET. The bulk of our projects are ASP.NET, some are Silverlight, and even less are WPF (though the WPF projects tend to be bigger in scope, so they're probably about even). Usually the customer has decided on a technology stack before we arrive, and they've engaged us to help plan/design/build/ship the application. Sometimes

Developing Native Android Applications: Not as Hard As You Might Think

Two months ago, my boss asked me to try and build a native Android application based on the mobile website I had created for the university's annual Maryland Day festival. Both he and I are part of an IT initiative in our department tasked with figuring out how best to provide IT services to smartphone users on campus, and while we have in-house expertise in iPhone development, none of us were

Error Handling – The C++ Way

In my experience as software developer, I noticed that there are lots of people that write in C++, but do not use exceptions. They prefer to use return codes instead. I guess that this is caused by the late addition of exceptions in the C++ standard. Whatever the reason is, personally, I prefer to use exceptions as an error handling technique. Almost 10 years ago I started programing in Object

Tron legacy

How the Tron:Legacy movie was filmed. I spent a half year writing software art to generate special effects for Tron Legacy, working at Digital Domain with Bradley "GMUNK" Munkowitz, Jake Sargeant, and David "dlew" Lewandowski. This page has taken a long time to be published because I've had to await clearance. A lot of my team's work was done using Adobe software and Cinema 4D. The rest of it got
