Editor's Comments

Yesterday, we at ASP Alliance published an article from one of our own. What to Know About Value Types and Reference Types in C# was written by Brendan Enrick, who is one of the editors here at ASP Alliance. In his article he is going back to basics and explaining how the Common Type System works. Specifically he explains the differences between the two categories of type it supports: value and reference. He covers null values and the Nullable type as well as briefly mentioning boxing and unboxing.

Suppose that we are dealing with a multi-language website: English, French, Chinese, etc. and in some forms we need to enter a username in three languages, each language in a separate textbox. Abdulla's custom control allows developers to add these three textboxs inside a custom multilang control that will reform these textboxes inside a sliding div that displays one textbox at a time for the selected language. This custom control includes two icons for each language: one in "on" case, and one for "off" case, so the end user can click in the language image that he wants to enter and the proper textbox will appear in the sliding animation using JavaScript code. He provides a comprehensive explanation of each step involved in developing the control with source codes and screenshots in addition to some of the tips and tricks for advanced functionality.

IIS 7 has a new User Interface and a new configuration system. In this article Sudeep provides step-by-step information on how to configure HTTP to HTTPS redirection which is a common requirement for Microsoft Exchange.

In this video, Mohammad Azam demonstrates how to handle schema mapping when using the SqlBulkCopy class to insert bulk data. His demonstration uses non-matching source and destination tables, and he uses mappings to allow the copying. He shows how to statically define mappings as well as how to write code which determines mappings at run-time. [6:12]

Value types and reference types are important concepts in C#. In this article, Brendan describes these concepts in an easy way. This beginners' tutorial is written to help people unfamiliar with these concepts to gain a basic understanding of them.

Warning: Use of CodeSmith may cause unforeseen productivity

July 2008 -- Business managers rioted outside the offices of CodeSmith Tools in Dallas, TX today complaining of developers 'going home early' and 'getting projects done too soon'. "CodeSmith does their work for them, they just write a template and hit 'run'," said one pointed headed manager, "it's just not fair! What with CLSA, LINQ, .netTiers, and more frameworks all just built in? With all of this productivity they might not need us anymore."
