I just posted a tutorial on using WCF RIA Services with DotNetNuke. This tutorial demonstrates creating a simple module that allows each registered user of a DotNetNuke website to create and edit their own Task list.

This tutorial also covers two important issues that are of interest to DotNetNuke module developers; implementing WCF RIA Services in a non WAP website, and securing and segmenting data for website users.

This program allows users to add unlimited rows of search criteria to filter a list. This example uses the DotNetNuke Users table (normally you would not want to connect directly to a DotNetNuke core table. It is only used as an example).

Even though there is a lot of Linq code to construct the queries, there is only one trip to the database to execute the query.

Today we released “Silverlight Bridge - A Silverlight 4 File Manager”



Silverlight Bridge can run in "Out Of Browser" mode and access the local file system and allow dragging and dropping of files from the local file system to the server.

Requires:

SQL 2005 or higher Silverlight 4 (currently in Beta) ASP.NET 4.0 (currently in Beta) VS2010 (currently in Beta) It will NOT run on ASP.NET 3.5 and Visual Studio 2008 Not for production use You can download it here: http://silverlightbridge.net

Fluent programming strives to provide for more readable code. Fluent validation provides more readable validation code. This is really important when you are building applications that have a lot of validation logic. There are two Fluent Validation ASP.NET libraries that I found:

TNValidate

Fluent Validation 

Because it was the first one I found, I decided to give Fluent Validation a try.

I just found out that the Microsoft Channel 9 program featured our DotNetNuke SketchFlow Viewer.

The link to the video is here:

http://channel9.msdn.com/shows/This+Week+On+Channel+9/This-Week-C9-IE8-most-secure-Unix-turns-40-SQL-DBA-eBook/ (they talk about SketchFlow for about 5 minutes and mention the DotNetNuke SketchFlow Viewer at about 23.18)

ADefHelpDesk does not really need an "Upgrade Advisor" but I made one anyway as a proof of concept for the DotNetNuke Core Project. There are thousands of users who do have difficulty upgrading DotNetNuke. My theory is that it should be possible to make a module that users could install before they do an upgrade that would identify potential upgrade problems.

Face it, Benjamin Hermann and his team's EALO is the "Tiger Woods" of DotNetNuke Open Source. It is the project that is so big and unstoppable that the rest of the DotNetNuke Open Source projects actually benefit from the traffic and attention that it brings.

As I pointed out in a previous blog (Effority is "King of the Forge), this module puts up numbers that are so big no other module comes close... at all.

In the spirit of "if you can't beat them join them" I have decided that since the "rest of the field" benefits from the success of "the leader" then it makes sense to help the leader.

Benjamin Hermann and his team (Oliver Dembniak and Johannes Ellenberg) plan to release another version of EALO for DotNetNuke 5 (the current version only works with DotNetNuke 4) on October 16th 2009. It would be great if EALO can get...

 

My wife bought me an Amazon Kindle (warning if you click the link and buy one I will get a "commission"). Because it was a gift I had to go to Settings on the Kindle and "de-register" it from her. I then went on the Amazon.com site, logged in as myself and entered the serial number on the back of the Kindle to register it to myself.

Ok now it's up and working. Kindle has this "Whispernet" thing which basically means it is able to communicate with Amazon.com without requiring...

This took about 4 months of part-time work but I finally got the Silverlight Bridge File Manager working enough so I can release it. This is actually just a small part of a larger project that is Silverlight Bridge. Silverlight Bridge will eventually allow you to see the files on your local computer and drag and drop the files from your local computer to the folders on the server.

Silverlight Bridge is a project that Ian started when he decided that you should be able to see your local hard drive in a Silverlight application. Ian did make a proof of concept that proves his idea will work, he just needs to flesh it out into a complete framework....
