1 of 3778 | Concurrent connections when consuming web services - Think I may have mentioned this before - but check out this post from Darren Jefford re. the low-level throttling of web requests when consuming web services from BizTalk....

2 of 3778 | Hacking files in BizTalk - The previous post on Sql debatching mentioned 'hacking' auto-generated files, something that may alarm some people (though not many, if my experience of developers is anything to go by.)Another example of this is the extraction of primitive values from auto-generated schemas, specifically (in my case) consumed web service responses. As an example, say that you consume a web service that returns a single value (acknowledgement id, boolean flag indicating that an update went through, you know the sort of thing.) Because these values are contained within the auto-generated reference.xsd files they are neither promoted (in fact they couldn't be promoted, as only passthru pipelines are supported......

3 of 3778 | Making WCF services amenable to testing - You know that using WebOperationContext.Current is BAD for making your service implementation testable, don't you? My friend Pablo Cibraro continued to evolve his ideas around decoupling your service implementation from this static dependency, and came up with the most simple yet totally unobtrusive (for production code) approach to this, which he calls WCFMock. The idea is quite simple: you can leverage C# class aliasing functionality (which few know it even exists) to conditionally (i.e. DEBUG vs RELEASE builds) replace the WebOperationContext implementation, like so:#if DEBUG using WebOperationContext = System.ServiceModel.Web.MockedWebOperationContext; #endif What will happen here is......

4 of 3778 | Microsoft Silverlight – Narrowing the Desktop Gap - Asynchronous (or multi-threaded) applications are common place on the desktop and have been for decades.  Without this ability, most of our favorite productivity tools would be non-existent.  As soon as one moves off the desktop and onto the Internet, the standard changes to one that is highly, if not exclusively synchronous (or single-threaded).  Of course, since Internet-based applications have historically served as simple content delivery mechanisms, the need for more robust, asynchronous-based applications didn't exist.  However, as more and more businesses move online with each passing day, the pressure for Internet-based applications to narrow the desktop gap is higher than ever befo......

5 of 3778 | What's new with web services in Silverlight 3 Beta - Cross-posted from the Silverlight Web Services Team Blog . Silverlight 3 beta comes with a set of exciting web services features that address key customer requests. Binary message encoding In Silverlight 2 the only supported binding was BasicHttpBinding, which encodes outgoing messages as text and sends them over an HTTP transport. This binding is great for interoperability with SOAP 1.1 services and is also easily debuggable since messages can be viewed in plain text on the wire using HTTP debugging...(read more)...

8 of 3778 | Five First Public Drafts of Web Services Specifications - 2009-03-17: The Web Services Resource Access Working Group published five First Public Working Drafts: Web Services Enumeration (WS-Enumeration), Web Services Eventing (WS-Eventing), Web Services Resource Transfer (WS-RT), Web Services Transfer (WS-Transfer), and Web Services Metadata Exchange (WS-MetadataExchange). The first describes a general SOAP-based protocol for enumerating a sequence of XML elements that is suitable for traversing logs, message queues, or other linear information models. The second describes a protocol that allows Web services to subscribe to or accept subscriptions for event notification. The third defines extensions to WS-Transfer that deal primarily with fragment......

9 of 3778 | Installing VSeWSS 1.3 - I’ve seen a few questions asking how to install VSeWSS 1.3.  This post walks you through it. First, download VSeWSS 1.3.  The February 2009 CTP is available here.  Once you’ve downloaded it, run the executable. Once the installer is running, you are greeted with the welcome page. Click next.  Then you’ll see the EULA page. Select the checkbox and click next.  Then you are prompted with the install directory.  I left the default.  Click next. Click next. Here’s the screen that causes questions.  The installer needs to create a web site to host a WCF service.  That WCF web service needs administrative privileges because it will ......

15 of 3778 | Eight Evil Things Microsoft Never Showed You in the ClickOnce Demos - Eight Evil Things Microsoft Never Showed You in the ClickOnce Demos (and What You Can Do About Some of Them) ClickOnce is a powerful and easy-to-use deployment technology that offers a relatively hassle-free experience for the end user when properly configured. The developer story for ClickOnce varies from super simple to maddeningly complicated, depending on what you are trying to accomplish. I recently wrapped up a project where ClickOnce was a large part of the release strategy, and also responsible for a lot of the headaches that went with it. If you use ClickOnce as it was intended, it’s remarkably effective. Knowing that most of you reading this article probably don’t use stuff “......

18 of 3778 | Code Generation Guidance Package - [Source: http://geekswithblogs.net/EltonStoneman] I've been working on a Guidance package which lets you use Visual Studio as a front end to generate items from T4 templates. Using a recipe wizard you choose your metadata from a Web service, database or file system source, and the template is rendered against each of the metadata objects you select. It's on CodePlex here: Code Generation Guidance Package, and comes in two flavours. The basic Guidance package has a single recipe "Add generated items" – when you run it, you specify a metadata provider, select the items to use for metadata and the T4 template to render against the items. The second package is a sample which extends the fu......

23 of 3778 | Small Confession - I have a small confession to make... A little TFS web service I built over the past few days was the first “real” production-ready application I’ve ever written from scratch where I’ve been good about maintaining unit tests. I even pushed myself to practice real-live TDD, and then even use Moq. I have to tell you, that I am now a firm believer in the benefits of leaning very heavily on your unit tests. Of course I've always believed others' stories, and have even worked on projects/products where I had to maintain a fair set of tests. But not having ever really tried it myself – on a new project where I could create real isolated unit tests, I think my belief was kind of shallow. Sort of......

I enjoy sailing, and I wanted to find historical data on windspeeds to know when would be the best time of year to set out on a long trip. (Answer: March and April have the best winds around Seattle). I found an excellent site, to scrape from, http://www.almanac.com/, which has historical weather data for many places around the country. The first step in scraping is copyright law. Facts alone are not copyrightable, but the act of selecting and compil......

29 of 3778 | Dezi! The Online TV - Dezi is a collection of online media streams (most of them live) that lets one have TV experience via the Internet! I used .NET 3.5 for the development ‘cause of the ‘Media Element’ that comes with it and also I wanted to do something with WPF! So anyways, I will chatter on how I coded the application later, but as for now, the working and usage style is unofficially documented! The application acquires the channels at startup from a Web Service! For now, most of the channels present on it are the ones broadcasted on Indian networks. I will adding more this weekend – German ones, I dunno, lets see! I also included the keyboard shortcuts in the application and are worth noting as below:......

Actually, it was getting really nasty out there, with drivers spinning on icy roads and bumping into each others’ car and subzero temperatures. Better stay inside, for sure! I would not feel guilty to dedicate a bit more time to keep developing the Image Slide control for getting images from Live Search through its APIs, described in part 1 of this blog series.

36 of 3778 | Installing the ASP to ASP.NET Migration Assistant on Windows Vista -   Note: The ASP to ASP.NET Migration tool was designed when ASP.NET v1.0 was just out and it does most of the conversion related to the then model.  Also, there are a few known issues and it doesn't do a near to perfect conversion.  If you are starting with ASP.NET development, the latest version is ASP.NET 3.5 which is a part of Visual Studio 2008 and I believe it provides conversion from classic ASP as well.   As a part of the upcoming Virtual Tech Days, I am trying to demonstrate on migrating from ASP to ASP.NET for all the world who is still left out with our ASP Days and currently working with similar scripting languages like PHP.

38 of 3778 | XML serialization, doubles, decimals and SQL Server - We just had a problem with data that is sent to SQL Server as a XML string. One of the values sent to the SQL Server is defined in the C# class as a double and interpreted as a 'DECIMAL(28, 9)' on the SQL Server. This was working so far. Just wen someone entered a quite small number (0.000013) it stopped working. The reson: 1.3E-05 is sent to the SQL Server and it can’t interprete this. It COULD be parsed on the SQL Server, although would involve some floting point madness that could mess up the value. The easyest would be to change the interface, but as we use the same class in the front end of a webservice, this would lead to an incopatability in the schema. Now, the solution we’re......

40 of 3778 | Equality Semantics of LINQ to XML Trees - In certain scenarios, it is important to be able to compare two XML trees for equivalence.  For example, if you are writing a web service that serves results of queries, and you want to cache query results so that duplicate queries use previously cached results instead of always accessing the underlying database.  However, the senders of those queries may potentially be using a variety of tools to generate the queries, and these tools may introduce trivial differences into the XML.  The intent of the queries may be identical, but XNode.DeepEquals returns false if you compare the XML that contains semantically equivalent, but trivially different queries. This post describes a......

Reliability and grid infrastructure improvements have taken the headlines, but since customer service is such a costly and critical mission for the utility, getting it right on the day when the Smart Grid is switched on will take foresight and planning. Or at least, it will take upgrades that will improve customer service and arm businesses and consumers with more information that will enable them to make more intelligent decisions concerning their energy usage for cost, energy efficiency and environmental purposes.

The Short and Sweet Blog version: The default menu.js will not contain any styles you define or select if you dont create a menu item prior to generating the menu with the AllWebMenus Tool. In your menu.js or customename_menu.js you will find a function named awBuildMenu()  in that function there are style objects that are created and instaciated  mostly they are named: its1 for itemstyle1 or grs1 for groupstyle1 ......

45 of 3778 | ASP.net hang in IIS 7.0 - When hosting an ASP.net web application on IIS7, and you have the application running in integrated pipeline mode, you may find that users complain that the application performs slowly.  This may occur if your website is busy, handling 12 or more requests concurrently, and those requests are handled asynchronously as opposed to synchronously.  The same application may appear to not suffer from poor performance when hosted on an IIS 6.0 server, or if the IIS7 site is set to run in Classic mode.    If you were to look at the currently executing requests in the IIS Manager by using the Request Monitor feature, you may see 12 requests currently in the ExecuteRequestHandle......

Where this can be useful is in providing a group or community with an email address that is relevant to them, along with the other existing services such as 25Gb Storage, Messenger and so forth.  The advantage of this is not in getting a free email ......
