In this tip, I explore one approach to building Ajax applications with ASP.NET MVC. I show how you can use view data when building Ajax applications with ASP.NET MVC in the same way as you would use view data when building server-side application. I demonstrate how to create a custom HTML Helper that renders client view data. One of the primary benefits of building an ASP.NET MVC application is that it enables you to build ...

I just published this open source project on Codeplex, and this information is available on the Writespace Codeplex home page as well. Writespace is a fullscreen writing environment, developed with WPF (Windows Presentation Foundation) as a ClickOnce installed add-in for Word 2007 . Unfortunately Codeplex cannot host ClickOnce applications, so to install the add-in you will have to download and run the installer locally until I've found a site to host it. Writespace is inspired ...

This major version adds static method support and non-public method faking to the AAA API. Check out the release notes. I don’t like the reflective approach to testing private methods. With the new additions to the AAA API, testing this class: public class MyClass { public string Public() { return this.Private(); } private string Private() { throw new NotImplementedException(); } } can be done like this: [TestMethod] [Isolated] public void PrivateTest() { MyClass fake = ...

For those of you using the ASP.NET AJAX Controls, there is a potential pitfall in how HTTP handlers are managed that can affect your AJAX applications. This issue may take a little bit longer to explain than most, but that’s because it involves a concept probably unfamiliar to most AJAX developers: the concept of HTTP handlers. For background, HTTP handlers are intimately tied to the way in which ASP.NET handles requests on the server. In ...

Every time I create an IIS website, I do some steps, which I consider as best practice for creating any IIS website for better performance, maintainability, and scalability. Here' re the things I do: Create a separate application pool for each web application I always create separate app pool for each web app because I can select different schedule for app pool recycle. Some heavy traffic websites have long recycle schedule where low traffic websites ...

I was recently working on a project that used WCF web services extensively. Everything was ready for deployment, I deployed to the remote host, and voila – nothing works (nothing WCF related). After a LOT of frustration, I managed to make it work. I found two areas which were causing the problem: 1. The .svc extension was NOT setup right at our host. You can set this in the web.config webhandlers section for IIS 7, ...

When you have a lot of controllers, you need to organize them under Namespaces. Also, it is better to put controllers under subfolders in order to organize them properly and have some meaningful URL for them like /Admin/User where Admin is the subfolder and User is the controller. For example, you might have a lot of controllers that are APIs exposed by your web app, not regular pages. So, you might want to put them ...

ASP.NET MVC Controllers can directly return objects and collections, without rendering a view, which makes it quite appealing for creating REST like API. The nice extensionless Url provided by MVC makes it handy to build REST services, which means you can create APIs with smart Url like "something.com/API/User/GetUserList" There are some challenges to solve in order to expose REST API: Based on who is calling your API, you need to be able to speak both ...

In this series of tutorials, I build an entire ASP.NET MVC application from start to finish. In this entry, I add a Silverlight file upload control to make it easier to upload multiple media files. This blog entry is part of a series of entries on using ASP.NET MVC to build an entire Family Video Website from scratch. Before reading this entry, you might want to read the previous four entries: Family Video Website #1 ...

Finally a solution!!!!!!!! How can we stream a shoutcast radio via a Silverlight application? Well in 6 steps... 1. Open Expression Blend 2. Create a Project 3. Add a media element 4. Add the code below at the cs (or vb) file public Page(){ // Required to initialize variables InitializeComponent(); this.Loaded += new RoutedEventHandler(Page_Loaded);}void Page_Loaded(object sender, RoutedEventArgs e){ try { myElem.Source = new Uri("mms://mystation:port/;"); myElem.Play(); } catch (Exception ex) { }} 5. We put mms ...

RMS says Cloud computing is a trap, and Ellison says He's sick of cloud computing. But still I think they're here to exist forever. It's little over hyped - just like any other new technology. But sure it's the next-gen model of computing.

If you’ve been working with Silverlight 2 Beta 2 you’ll be happy to know that the release candidate was just released. You can get it at: http://silverligh... Scott Guthrie has a detailed post on the new features but here’s a high-level synopsis of what’s new since Beta 2: PasswordBox control added ProgressBar control added ComboBox control added New control templates (they’re much cleaner than the previous ones IMHO) API changes here and there and elimination ...

From MSDN... "Deep Zoom enables the ability to zoom almost arbitrarily large images in Silverlight in a performant manner."This is still the most ridiculously over-used word in tech circles, because it's made up. It can, technically, be used as a noun, but "performer" is more common. Seriously, with so many English majors writing code these days, how does this happen? I guess I find its use agitant. ;)

In one of my previous posts I showed how to embed GPS coordinates to jpeg images using C#. It is mainly useful if you're using a maps+pictures services such as panoramio.com or everytrail.com or any other kind of mapping and pictures solutions. My GPS buddy is a nifty HOLUX M-241 GPS among the regular location, speed, direction, time it can also records tracks, and on top of that it's rather cheap. But unfortunately it's image ...

After setting up a crawl rule to crawl something other than SharePoint sites (such as a file share), you may encounter some errors for SQL Server. If you start to see these repeatedly - check that you have the latest service pack for Microsoft SQL Server 2005 installed. That will resolve your issue. If you aren't sure how to check, see this post: What service pack is on my SQL Server? Event Type: Error Event ...
