Welcome to Imar.Spaanjaars.Com

As you may know, my Contact Manager application used in my new series on N-Layer design using ASP.NET 3.5 is fully localizable. That is, the site is available in two languages - English and Dutch - and users can choose the language they want to see the site in. The concepts behind the localization process are all built in to the ASP.NET framework and didn't require a lot of work from my side.

Shortly after I published the article on localization, I received an e-mail from a reader asking how he could use the same principles to translate client side JavaScript. He had written some custom JavaScript code that displayed messages to the user and he wanted an easy way to translate those messages as well. The good news is: it's pretty easy to do....

In my article series on N-Layer design I credited AzamSharp for his article on creating a domain object validation framework. AzamSharp didn't cite any other resources so it looks as all the ideas presented in the article are his.

I am proud to announce the launch of my new web site: www.DotNetAttributes.com - the definitive source for attributes in .NET.

Note: this is part five in a series of six. If you rather read this entire series off-line, you can buy the series as a convenient PDF document that comes with the full source. Besides the convenience, buying the PDF will also make you feel good as it shows your appreciation for the articles and helps me pay the bills for my server and hosting so I can keep running imar.spaanjaars.com and continue to provide you with great content. For more details, check out this post that shows you how you can buy the entire series right now.

This is part five of a six-part series of articles on N-Layer design. This article series builds on top of my three part series on N-Layer design that I released in early 2007. If you haven’t already done so, be sure to check out these articles first, as a lot of code and concepts used in this new series is explained in detail in the older series.

In this installment, I’ll discuss techniques for dealing with concurrency — I'll show you how to handle data conflicts caused by updates from other users.

A while ago I was approached by Packt Publishing to see if I was interested in reviewing a copy of one of their books. The topic of the book they had in mind (ASP.NET 3.5 Social Networking) is closely related to my own work so I said yes.

It's finally here: the VB.NET version of the demo application from my article series on N-Layer Design using ASP.NET 3.5.
