When you’re creating software, it’s always a good thing to let the people who you’re creating software for know how it’s going to look and feel. Not the simplest task at hand; creating a good mock-up of a screen involves some serious thinking and figuring out what a client would like / need to have

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. The result is a flexible dynamic way of building a where predicate. Linq generates pretty good and effective queries from the predicates. Very nice! http://www.talentgrouplabs.com/blog/archive/2007/11/26/dynamic-linq-queries–dynamic-where-clause-part-2.aspx

Out-of-the-box, the Microsoft Office SharePoint Server comes with a search engine, which is the 2008 Search Server. It’s capable of crawling different content sources via http, by requesting the page, indexing it and visiting links on the page after that if you prefer to. Now within SharePoint sites this is all pretty straightforward. The crawling of internet

These last couple of days, we’ve been working on fixing a bug. The application it occured in works together with a Progress proxy object which talks to a Progress database. Because that link isn’t too transparant, it was very difficult tracing the bug and finally coming up with a solution for it. The problem occured

The ‘News site’ site template of MOSS 2007 is probably one of the most used templates for companies which use SharePoint for their internal intranet. It allows you to add news items to a specifically designed site in a user friendly way. Editing the news items is done on the page itself, with extra functions

Unfortunately for me (but not unfortunately at all I guess), not all software developed right now is .NET based. That’s fine because there are a lot of other really good alternatives out there which do the trick and in some cases even do the same trick even better. And even when a .NET based application seems to

Today, while working with the Linq designer, my Visual Studio installation started throwing errors at me. They stated ‘Operation could not be completed’ followed by some Dutch nonsence which didn’t help much. At first, I thought this had to do with me altering the database structure and then opening the Linq designer again. I tried deleting some
