My friend Fabien Lavocat from Microsoft France recently sent me an email regarding a Visual Studio 2008 survey they have just started. The survey is of course available in English.

For french developers willing to obtain Microsoft Developer certifications, a colleague of mine (Julien Dollon) has just published a very useful website that will help you prepare for the certification exams: I wish Julien good luck with his website and trust it will be a great help a lot of developers.


Hello, for this second blog article I've decided to explain this neat little feature of MySQL: SQL_CALC_FOUND_ROWS and FOUND_ROWS() . This article is about MySQL only, it is likely that these keywords/functions exist in other SQL-based languages but I've only ever used them with MySQL. What's the point, you ask? When working with (my)SQL databases, you often find yourself using the LIMIT keyword, in order for example to limit the results of a large search. Let's study a particular case. - You're working on the "employees" table, which contains, say 1000 data rows. - You wish to display the list of employees in a particular department, 10 by 10. - You wish to display the amount of employees in this department .

And here I was thinking the World Wide Web had all the answers. Perhaps my contributions will help some of my fellow developers! This first article is about how to draw a video using the MediaPlayer class in WPF (C# only - my apologies to VB.NET users: I'm allergic to VB). I was in the middle of preparing a training session at Avanquest Software when I read something in the WPF MOC: using the MediaElement control isn't the only way you can draw a video on a surface. Doh! I investigated a little further on the subject but couldn't find anything on the subject. What does this do? This article will explain how to use the MediaPlayer class to play a video on a surface. To demonstrate the wide range of possibilities offered by this mechanism, I will explain how to draw the same video clip on 9 different controls simu
