This brief article will present how we can leverage the magic of JQuery to load partial views via AJAX calls into an ASP.NET MVC application. It is really quite amazing how the power of JQuery dovetails so nicely into ASP.NET MVC.

In part 1 we built a simple web chat using Silverlight 2. Now, we are going to add functionalities so that users are able to choose from multiple chat rooms as well as chat privately with other users.

NerdDinner.com is an event management site so computer folks can meet and talk technology over a meal. It uses ASP.NET MVC along with jQuery, ASP.NET Ajax, Virtual Earth Javascript controls, and LINQ to SQL. It’s also a real site running at NerdDinner.com that you can use to schedule geek meet ups and nerd dinners in your neighborhood! It’s Open Source and hosted at CodePlex so you can expect to see updates and new features in the coming months.

Are you all of the sudden getting “Internet Explorer cannot display the webpage” / “Address Not Found” when trying to run a web application from inside Visual Studio?

This caused me a fair bit of headache yesterday, so now that I found the solution, I figured I’d try to spread the word.

Basically what’s happened is that an update for “Windows Defender and Microsoft Forefront Client Security” in the form of a new signature file was released on the 9th of March (Signature versions 1.53.283.0). This update was to address possible scenarios where a machines host file might get changed by a trojan or the like. Unfortunately however this had the side effect on some systems that the localhost entry in the host file was removed or corrupted, leading to any attempt to got to http://localhost/[whatever] will fail.

The solution as outlined in the links below in further detail, is to re-add the localhost entry (127.0.0.1       localhost) to your host file (C:\Windows\System32\drivers\etc\hosts).

I appreciate that these things are important etc. but for [insert appropriately bad word here] sake Microsoft, if you push out potentially breaking changes let us know!

In my case what happened was that, as a good Windows user I have automatic updates turned on and I let the machine restart when it needs to etc. Yesterday, after I’d not used Visual studio on my laptop for a couple days,  all of the sudden while sitting on a bus trying to do some Silverligth stuff, I couldn’t display any html pages when running then from VS. After some attempts at working out what the heck was going on and being on a bus with no internet connection I had to give up and pack up my laptop. Later after 30 min of Googling I found these two post helping me work out what had happened.

So I guess Microsoft had let us know in the way that the “Visual Web Developer team” let us know on their blog but come on, this should have been more publically announced in some way, according to some of the comments there are people out there who have struggled for days with this issue. I’m not really sure how they should have done it and maybe I’m just irritated because I got stung, lesson learnt from this. Turn off the automatic update and apply updates manually, once you know what they’re doing!

Happy coding :)

Yet another self project for this week. Yes it is a Multi Remote Desktop Client .NET (.NET 3.5) written in C#.

The article attempts to demonstrate a way of testing in the .NET framework. This is just a demonstration of how we can do automated testing in C# .NET.

For a current project I needed to create a table that contained a list of exclusions that should be filtered out from another table when a specific set of criteria were met. This is a pretty common scenario where you have a large table of data and you want to be able to provide the ability through a user interface for a user to filter the data using an exclusion list.

ASP.NET is expected to have some improvements on the generation of client IDs.

Although this is a major improvement, it comes short by not allowing the generation of shorter client IDs for server controls.

My good friend Nuno Gomes has done some work on generating shorter client IDs for controls (*).

Jeff has taken it one step further with his How to shorten ASP.NET automatically generated control IDs article on CodeProject.

If you want to see a running example, check out http://www.biocompare.com/.

Hi all.

You can check my video on SQL Server 2008 new data types. I’ll be posting some more videos soon.

Thanks for watching.

Our Guest: Jean-Paul Boodhoo

Our special guest this week is Jean Paul Boodhoo who is a developer, trainer, and author specializing in .NET and Agile development. When I first heard about JP’s summer where he worked while traveling around the world after giving away the contents of his home – I knew I had to have him share how he did it.

Truly Going Paperless

While very few of us will have an opportunity to have such a grand adventure as JP and his family did his techniques are something we can all benefit from. In this show JP shares how he uses the following services to be 100% mobile keep a paperless office:

• Earth Class Mail: global PO box with options to send parcels to wherever you are in the world
• Neat Co: scanning, storing and working with receipts
• eFax: for faxing documents via email
• Skype: Unlimited
• LiveMeeting: with active speaker switching for video conferences
• UltraVNC: for remote pair programming

Getting Things Done

I got a copy of  Getting Things Done  for Christmas and quickly became energized by David Allen’s concepts. I discuss in the show how I use custom Gmail accounts and a defined workflow to implement the tenants of GTD. Gmail’s labeling, search, archive and starring features make a great way to keep track of projects and next actions.

Further I use the service, 3mindme to implement a digital  ticker file  (see the book for an explanation!). Finally, to keep the accounts accessible I use SlickRun to map each mail account to a different browser so I can keep each account authenticated… works like a champ!

If all of this is foreign to you I  suggest you get a copy of the book for yourself and find out why the GTD concept is so practical.
