Lately I've been working pretty hard on different projects but not really stumbling upon anything blogworthy. The most recent project is quite interesting though, a single page, touch friendly, web application using the latest and greatest technologies. We've ended up with using Brunch with Chaplin , which is a very neat way of setting up a Backbone based single page web project with Brunch and Chaplin . Aside from this, I have my own little project that has lived on for almost 15 years already, The Cornball . From being a plain Windows application written i C an Win32 API, it has been ported to .NET using WPF, and is currently a Silverlight application hosted on Windows Azure. I could not find a better time to reanimate this project and create a new web based version, touch friendly, super optimized, awesome in any way. So I did... So please follow my journey at Github . It's going to take a while, I assure you, but I already have some ground work done. Meanwhile,...

Performing an asynchronous file upload from the browser is a common problem with almost as many solutions as there are developers. The following solution is the best fit for my needs, and also works well with most popular browsers. Backwards compatibility is not an issue in this case which is great, because I can use the new technologies as they are supposed to be used. Everything is put together in JSFiddle for a working example . I will continue to explain the parts below... First, the input field needs to be styled as a button. The form tag is only present for us to be able to reset the file input field later on. <form>     <span class="fileUpload btn btn-default">         <span class="glyphicon glyphicon-upload"></span> Upload file         <input type="file" id="uploadFile" />     </span> </form> .fileUpload { position: relative; overflow: hidden; } .fileUpload inpu...

I wrote this post almost a year ago, but never published it for some reason. Anyway, here is a little MVC/MEF magic. By default a controller in MVC must have a parameterless constructor. When using MEF a good practice is to inject the services via constructor parameters. These two in combination obviously creates an issue where the following scenario will not work out of the box, since there is no parameterless constructor for  MVC  to use. Note that the PartCreationPolicy is set to NonShared since a new controller have to be initialized for each request. [Export] [PartCreationPolicy(CreationPolicy.NonShared)] public class HomeController : Controller {     private readonly IServiceClient _service;     [ImportingConstructor]     public HomeController(IServiceClient service)     {         _service = service;     }     public ActionResult Index()     {         ...

In WPF , the RichTextBox  control is not really like other controls. Due to its flexible nature, there is no built in way of binding a property to the content. In this case, I wanted a simple  RichTextBox  control with a binding to an HTML formatted string to be able to use the built-in formatting features of the  RichTextBox  and allow users to create simple HTML formatted content. First, doing the conversion on-the-fly proved to have major performance issues, so I ended up binding the content to a XAML string. The XAML to HTML conversion can be performed at any time. I created a UserControl with a bindable Text-property. The view contains a  RichTextBox  control. <RichTextBox x:Name="richTextBox" TextChanged="OnRichTextBoxChanged"> The source code for the user control contains the Text property and the methods to handle the binding. public static readonly DependencyProperty TextProperty = DependencyProperty.Register( "Te...
