Only a few days left before DevDays11 will start in The Netherlands, and while a large part of my schedule is fixed already I decided to run through the agenda and pick a few sessions anyway.

My main interest during DevDays will be Visual Studio LightSwitch, as you will be able to find me most of the time - at least in between sessions - in the Ask The Experts area at the VS LightSwitch boot. So naturally I highly recommend the sessions Beth Massi will be giving on the topic. She's doing 4 of them, one of which during geeknight, so I'm sure you'll be able to catch one.

On april 28th DevDays my highlight will probably be:

9:15 The KeyNote. Keynotes are always a blast.
11:05 Not sure yet, but I might just try and catch the Windows Phone 7 Mango session by Ben Riga.
13:30 Going for the session on REST with WCF by Glenn Block, since I already know a bit about LightSwitch.This timeslot also features Beth's first session on LightSwitch. If you're new to LightSwitch, check it out.
15:05 That'll probably be Mark Miller on UI. It's been a while since I've seen him speak.
16:30 I'll probably try and learn something about Azure this timeslot. But then again I might also pick up on Beth's second appearance on LightSwitch, since we might get questions about that on the boot.

Geek Night night is not something you should plan for, so we'll just see what happens.

9:15 No possible way of predicting how things will look during the first session after Geek Night. So I decided not to plan anything here.
10:50 Only one possible option: Beth Massi on Advanced LightSwitch Techniques. That'll be awesome!
13:15 This will be a hard one. Of course there's Mathijs on WP7 Push Notifications, but there's also Ingo Rammer on Advanced Debuggin in VS2010 which will probably be very useful too.

For the remainder on the conference I actually expect to be busy on the ATE stand for LightSwitch. And I'm looking forward to it too!

Hope to meet you there

Today I tried to upgrade my DNN Skin Development installation from 5.3.1 to 5.6.0
I got a SQL provider error on the 5.4.0 script I did not understand at first.

I got this error

System.Data.SqlClient.SqlException: Violation of PRIMARY KEY constraint 'PK_TabModuleSettings'. Cannot insert duplicate key in object 'dbo.TabModuleSettings'.
Violation of PRIMARY KEY constraint 'PK_TabModuleSettings'. Cannot insert duplicate key in object 'dbo.TabModuleSettings'.

I took me a while but I found the reson for the failure and the solution.

There are several blog posts about Stylesheets in DotNetNuke, but they mostly cover only a part of the subject.
I tried to wrap up all the information on what stylesheets DNN loads and how to manage them in one blog post.
- What stylesheets are loaded and why
- In what order they are loaded
- Use of Ids / Classes for containers
- How to limit the number of stylesheets DNN loads
- Why you should not delete or edit Default.css

If your skin has a dark color or an image as the background, there are situations were this background is visible in the editor too.

There are a lot of posts in the DotNetNuke forums about cross-browser issues in a DotNetNuke skin.

Installing DotNetNuke on Windows 2008R2

Windows 2008r2 is good in so many ways, I can never list them all. Of course, being the server variant of Windows 7, it means you can use all the nice interface enhancements that are also available in Windows 7.

Both Windows 7 and Windows 2008r2 have IIS 7.5 on board. One of the most interesting enhancements in IIS 7.5 is something called the Application Pool Identity (AppPoolIdentity). In Windows 2008r2 this is the default setting for new application pools. With this setting, IIS can create a unique virtual windows account, using the name of the application pool. Accounts created like this have the same networking capabilities as the well known NETWORKSERVICE account, however, because they are unique, they can also be used to secure physical files in your system.

So, lets see how we can use this to quickly install DotNetNuke in a secure manner.
