I just posted an article on deploying a Microsoft Visual Studio LightSwitch application to your DotNetNuke website. An important thing to note, is that you can use your existing DotNetNuke users and roles with your LightSwitch applications. This is really important because you already have accounts and roles. You don’t want to require your users to learn a new username and password, and need to log into, each application. Deploying your LightSwitch applications in DotNetNuke allows a seamless user experience. ...

A year ago Ian Lackey and I decided to create a DotNetNuke site that allowed users to upload .Mp3 files and play them using Silverlight visualizations. We planned to expand the site and to make a SDK so that people can create their own visualizations. However, we became busy with our latest DotNetNuke book, and other projects, and we never got around to making the enhancements. ...

 I just posted a new DotNetNuke Silverlight 4 View Model (MVVM) module. This module allows you to easily gather, and process Expense Reports, from users in your DotNetNuke portal. Advantages of Using Silverlight It is faster - When viewing the Expense Reports for a single user, there are no post-backs. The application moves considerably faster than a normal web application....

When using web services with DotNetNuke, there are three primary methods to secure the web services that I use: Using Http Context – When a user logs into your DotNetNuke website, their web browser is given a “authentication token” in the form of a cookie. Web service calls made using Ajax or Silverlight, use this cookie for authentication. This cookie will “time out” like a normal log in if it is not used for a period of time (usually 20 minutes). Using A “Custom Token” – SilverlightDesktop.net...

At the last Southern California DotNetNuke Users Group, we had Chad Nash From Data Spings. He talked about using JQuery in DotNetNuke modules and all the tips and tricks he has learned. At one point he casually mentions that Data Spings has two free services: RESX Translate – A free service of Data Springs, Inc....

 You are probably thinking “Didn’t he already post a free DotNetNuke Silverlight file Uploader ?”. Well yeah I did, but this one is different. This one allows a DotNetNuke portal administrator to place an instance of the module on a page and upload files. Each file has the ModuleID saved in its database record. The module will only show files for that module instance. ...

If you have a page that contains a lot of information for users to enter, you can run into a problem where their authentication will “time out”. Usually this authentication is set to expire after 20 minutes of “inactivity” (the user has not submitted a request to the web server). The problem is that if they, for example, click the Save button after their authentication has expired, their content is not saved and they are logged out of the site instead.  ...

 At my day job we have an advanced developer who was given a difficult project where he has to implement a dozen business rules. I’m talking “ask for a blessing before you go in” and “ask for forgiveness when you come out” complicated code. I watched him work on the code, and he is methodical at writing down the rules and writing a test case to make sure he properly implemented...

 I just posted a module that allows you to easily create a sign-up list of verified email addresses. A DotNetNuke portal administrator can place an instance of the module on a page and customize the sign-up message and the email verification message. The captured data can also be exported to Excel. The module and code are posted here: http://www.adefwebserver.com/DotNetNukeHELP/Misc/SignUp/

 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. ...
