New Job

Quite some time passed by with no new entry in my weblog. This has to change. So here is the big news.

2nd November 2004 I started a new career, I'm now an Application Development Consultant (ADC) for Microsoft Austria.

It's my responsibility to help our customers to solve technical problems when developing applications with Microsoft Technologies.

SQL Server Usergroup Austria Summeracademy

Yesterday we had the first MS SQL Server 2005 event from the SQL Server Usergroup Austria Summeracademy ( It was a full success, many of our members had for the first time in their lifes the chance to use a Microsoft SQL Server 2005. We did many Hands On Labs with topics like T-SQL Enhancements, XML, .NET Integration and SMO.

New Article released

Open your favorite .NET application, then close your eyes and try using the program. Tough, isn't it? But that's what using your applications may be like for disabled computer users. As a responsible developer, you can solve this problem by using these techniques to add Active Accessibility features to your application.

My new article called How to Build Accessible Windows Forms Applications with .NET has been released at

MCP Exams...

Congrats to the attendees of my MCP Curriculum in Schlieren (Switzerland, near Zürich). All of them passed the exam!

Teaching MCAD in Zürich (Switzerland)

Well, i haven't written a blog entry for some time now, so i thought I'd just inform you about what's going on in my life...

1) right now I'm teaching a MCAD Curriculum in Zürich. It was organized by the local Usergroup Leader, Stephan Troxler and we managed to arrange really cheap rates for the attendees. 2000,- Euro for 2 weeks full of .NET Knowledge.
Last week we started on monday with a quick overview on C# and object orientation. The next days we worked through the MOC about Programming the Framwork with C# (Signing, GAC, Assembly Binding, CodeAccessSecurity, Delegates, Multithreading, HelperClasses,  and all that neat stuff that helps you to make rock solid applications). On Friday we started with ADO.NET and saturday was completly focused on a WinForm Application and the usage of the CurrencyManager.
On Sunday finally a day off - went to Singen(Hohentwiel) (Germany) for a short walk on an old eroded vulcano.
Monday back at school with ADO.NET and we are focusing on ASP.NET Development.
On thursday will be the MCP Exam.......  good luck to all my attendees.

2) Still working on the website for the Vienna Symphonic Library at   This project just doesn't want to get finished... Still lot of coding work to do and there are also no indizes on the database because it's all still in development...

3) Working on a Texture Generator for Serious Magic ( I love this project, specially for the technologies I use here: ATL, MSXML, .NET
And of course I'm going to implement all the neat gfx algorithms. These are already finished: Perlin Noise, CellularPattern, Glowing Rectangles, Gradients, Blend Functions, Bump Mapping, Displacement, Expose, Color Adjust, Affine Transforms, Matrix Operations and many more.
Seems like this will be one of the best tools I've build 'til now.

Well, this is enough for now. Don't expect a major update in the future because I'm really busy....
