Hello World of VS

Posted By: Daniel Cazzulino     Posted Date: August 21, 2010    Points: 0   Category :ASP.Net

At Clarius we've spent years doing Visual Studio extensibility. Literally. We LOVE doing so. We did so much of it during the years that chances are pretty high you've been using some of our stuff (fully or partially developed by us) at one point or another. A non-exhaustive list includes:

Hello World to C# Threading Part 1

In this post we will see how we can implement simple threading. Why do we need threading? When you want you application to do more then one thing at same time, then you need to implement threading. One usual and common scenario would be when your application needs to get data from some other resource like web services and you don't want you application GUI to be freeze during this time. In that sort of case you will run the code to access web services in separate thread so your application GUI won't freeze. The System.Threading namespace .NET provide interfaces to implement multi threading.

Event ID 1011 - DefaultAppPool World Wid Web Pub. Serv. fatal communication error

We have a Windows 2003 server running IIS6 1.1 Framework. We have also installed a DNS and Active Directory in the same machine.

We're randomly getting the error you can see below. Sometimes it causes the recycling of process w3wp.exe (which on my understanding represents the application pool worker processd) and other times results on this process hanging and not responding to any request. To do iisrest temporarly solves the problem.

We were pointed to a possible permissions problem between the user we were runnig the DefaultAppPool with and registry entries used by the iis. We noticed the default predifined user we used, Network Service, wasn't found in the Active Directory, so we changed it by the default configurable user, IWAM_MACHINE_NAME, which is under the IIS_WPG Active Directory Grupo, which, in theory has the correct permissions to run the application pool.

Well, none of this worked and we are still getting this error.

This is driving us crazy and think the problem might have to do with having the Domain Controller/Active Directory and the IIS6 running on the same machine. We'll try now uninstalling this DC pointing to another one to see what happens.

Any help would be appreciated.

Thanks in advance,

Yukon Basics: XML, T-SQL, and the CLR Create a New World of Database Programming


The next version of SQL Server, code-named "Yukon," includes quite a few enhancements and expanded language support. For example, Transact-SQL now conforms more closely to the ANSI-99 SQL specification and makes querying more flexible and expressive. Yukon can execute user-defined functions, stored procedures, and triggers written in CLR-targeted languages, including Visual Basic .NET and C#. It supports a subset of the W3C standard XQuery language, and has native XML support.In this article, the author outlines the most significant language features and builds an order-entry sample app.

Real-World XML: Manipulate XML Data Easily with the XPath and XSLT APIs in the .NET Framework


XPath is emerging as a universal query language. With XPath, you can identify and process a group of related nodes in XML-based data sources. XPath provides an infrastructure that is integral to XML support in the .NET Framework. The XPath navigation model is even used under the hood of the XSLT processor. In this article, the author reviews the implementation details of the XPath navigator and the XSLT processor and includes practical examples such as asynchronous transformations, sorted node-sets, and ASP.NET server-side transformations.
