On this page you will find an overview of all articles that I have written since 1997. The more recent articles deal with software development with .NET (C#, Visual Studio, LINQ, WPF, Silverlight, WCF RIA Services, ...) in particular. The older articles were often written for the purposes of courses or demonstrations at my computerclub and these articles are mostly about photo editing, databases, Windows, Office, Delphi and PHP.
Below the most recent additions are shown. Use the left panel to filter the more than 100 articles.

The Entity Framework together with LINQ to Entities are very powerful technologies to access and manipulate data from a database. But when you need to gain performance or need extra security, stored procedures and user defined functions are often required. In this first article in a series of three I will focus on how to use stored procedures in the Entity Framework 4.0.

Visual Studio 2010, .NET 4.0 and Silverlight 4 offer a lot of new features.

Silverlight and RIA Services are great technologies and the Model-View-ViewModel (M-V-VM) pattern is a nice approach to keep UI and logic separated. But using the combination of view models with item controls, dataforms and commands can be a laborious task because the databinding features in Silverlight are quite limited. In this article I will demonstrate how binding with ViewModels can be improved by using the BindingHelper class and by creating your own command behaviors. more

A common problem when developing Silverlight applications is how to share classes and in particular (Entity Framework) entities which are compiled for the full .NET framework in a Silverlight application.

Data binding is one of the most powerful features of WPF/Silverlight. It allows developers to achieve more with less code. However, when building user interfaces with WPF/Silverlight, you often need to create your own value converters.
