| The Latest from The Problem Solver | MORE | | Introducing the LearningLine The first course material I have done for the LearningLine is a 4 day course on RavenDB. Using this course you can learn how to use RavenDB , complete with exercises and support if you want it, over 4 or 5 evenings. Recently we have been working on something new at DevelopMentor for online teaching. still really like teaching in the classroom and I think that this is a great environment to learn new material. But it is also a very expensive and not very scalable way of learning. So we are starting a new way of learning on the internet. In a hurry? Want to learn more? Enjoy! The Problem Solver - Monday, February 18, 2013 | | The Best from The Problem Solver | MORE | | Using Model – View – ViewModel with Silverlight Of course there is no need to duplicate properties the UI is never going to bind to directly. The View – Model – ViewModel design pattern, also known as MVVM, is getting more popular these days. have found it extremely easy to use when developing very different applications and have used the design pattern recently in both ASP.NET, WPF and Silverlight applications. However easy as it might be is seems to confuse people as I have seen some terrible examples where people make a complete mess of things. The View is data bound to a ViewModel. This is the most important step to remember. The Problem Solver - Tuesday, April 7, 2009 HTML 5 and file Drag & Drop Of course as always not every browser supports the new feature. There is a lot of new goodness in HTML 5 and one of these features is being able to drag a file from the Windows explorer into the browser and handling the drop event using JavaScript. If you are a GMail user you are probably familiar with this as GMail allows users to attach files to emails using this Drag&Drop style. This works just fine with the current versions of Chrome or FireFox though. The HTML page I am using is real simple and looks like this. 1: 2: 3: 4: HTML 5 Drag & Drop demo. 1: $( function () {. Enjoy! The Problem Solver - Thursday, October 13, 2011 Using SignalR for real time data updates Of course we can add some code to actively check for changes to the data but usually there will be no change so that results in a lot of useless network traffic. In a previous post I showed how easy it is to create a simple chat application using SignalR. And chatting on the internet might be popular but as it turns out there are rather a lot of applications that need to do more than just chat. As it is there are a lot more CRUD style applications, where users edit data usually stored in a database for some purpose, than chat applications. And that will remain so until reloads the data. The Problem Solver - Wednesday, July 25, 2012 | - Flowcharts in Workflow 4 and the Switch activity
Of course the FlowSwitch should just to a ToString() on the expression result , anything else would be pointless as any comparison fails. Flowcharts are a nice addition to Windows Workflow Foundation 4. They allow for a lot of pretty complex behavior that is hard to do in a sequential workflow. In WF 3 we used to model these complex behaviors as state machine workflows. That worked but they weren't really state machines or event driven and things could get a bit tricky. No it is just another activity to drop in a workflow. guess you get the picture. So far so good. Next (5). Enjoy! The Problem Solver - Tuesday, October 27, 2009 - More Workflow 4 Services and duplex communications
Of course they don’t receive the data being passed in the callback so that is something to keep in mind when deigning your workflow. Yesterday I posted a long blog post explaining how to do duplex communications in a Workflow service. Also the callback address had to be passed by the client using CallbackContextMessageProperty and the workflow service had to use a callback correlation handle to connect the Receive activity with the Send activity used for the callback. So what is the problem with this? As WCF callbacks are not supported using a ServiceHost on the client is unavoidable. The Problem Solver - Tuesday, May 4, 2010 - Paging with the Silverlight RIA services DomainDataSource
Of course it is just a matter of setting properties so doing so from code is easy enough. Using the declarative DomainDataSource that is part of the upcoming Silverlight 3 RIA services makes it quite easy to work with data. All you need to do is add a DomainDataSource control to the the XAML, point it to the generated DomainContext class (in this case NorthwindContext) and tell it which method to use to load the data from the web service(in this case LoadCustomers). Next add a DataGrid to display the data and you are good to go. Adding paging. Using progressive loading. Enjoy! The Problem Solver - Monday, April 27, 2009 - HTML 5 feature detection aka Modernizr
Of course if JavaScript is disabled Modernizr can’t add a css class to you must add the no-js class yourself. Yesterday I blogged about using the new Server-Sent Events or the EventSource object to send messages from the server to the client. But what happens if I try to do this in a browser that doesn’t support Server-Sent Events? These days that is no linger a recommended approach as browsers are updated frequently and keeping up to date base on browser versions would be a nightmare. better approach, and much more common these days. is feature detection. 2: // Good to go. 4: else {. The Problem Solver - Tuesday, November 8, 2011 - NuGet and projects under source control
Of course that isn’t perfect, some assemblies are installed into the GAC and can’t be treated this way. NuGet is one of those awesome additions to Visual Studio that I wonder how I could have gone for that long without it. And as I am not the only one who likes it we had a bit of a discussion on Twitter last week about how to go about using NuGet with projects under source control that are shared by multiple users. The problem is nothing new and has been around forever. So far so good but what happens if you commit your changes to source control and another person does an update. The Problem Solver - Tuesday, April 12, 2011 - How to get started with Knockout.js
return viewModel.firstName() + " " + viewModel.lastName(); }); Of course we still need to tell Knockout to use the ViewModel and that takes all of one line: ko.applyBindings(viewModel); So the complete JavaScript in my page is now: $( function () {. Once you get into doing more client side JavaScript code with business applications and REST services you are going to run into the question of how to construct the client side HTML required to show the data to the users. Your code might look something like this $( function () {. $( "#btn" ).click( click( function () {. $.getJSON( The Problem Solver - Monday, February 6, 2012 - On building Restful services
Of course the WCF Web API is still in a preview state so some of the technical things are subject to change over time but the general principal of building Restful services isn’t going to change a lot. I recently did a few blog posts showing the basics of how to get started with the WCF Web API but before I continue I think it is best to start with the why instead of how. lot of people will be familiar with writing SOAP style services but not everyone is quite as familiar with the REST approach so I guess that takes a bit of explanation.
