I faced a problem on my development machine. The following symptoms were visible: 1. The services.msc window only displayed the “standard” tab correctly. The extended / advanced tab was broken and only displayed the topleft blue bar. No text, no services, nothing. 2. In my Project installation (2007 office client) all the web panes broke.

Because a lot of people keep e-mailing me about the code I wrote for the Crystal Reports webpart, I decided to make it available for purchase. Unfortunately not for free, since my boss seems to think I have to get paid for the work I do. If you are interested in buying the webpart (it’s

In my last post, I wrote about enabling access to SQL Server Analysis cubes by specifying an account for impersonation. It now seems that’s not the way to go because I started receiving security validation errors with impersonation set to any account. I think that’s caused because SharePoint detects a difference between the user actually

This is the error message I was getting on one of my SharePoint sites. I was really lost and ended up creating a new site hooked up to the old content db, after which is was working again. Except for one part of the site which involved getting data from a SQL Server Analysis Server

Today I ran into a very strange problem with one of my web app’s. After migrating it to a new server, a ODBC link stopped working. The only differences between the two servers were the OS: XP on one and 2003 R2 on the other.

I just wanted to quickly share a pretty nice article about dynamic where predicates in Linq. It requires a little class to make AND and OR combinations with different predicates.
