DevelopMentor Courses - Tuesday, March 5, 2013 - 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 - 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 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 - 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 - The value of Pair Programming
Of course, another value of the pairing overlap comes from just looking at the mistakes. Gary Filer made an interesting comment to me the other day; “I use to think that the value of pair programming was the shared brain” “But after seeing you pair for the last week, I realized that the shared part is actually the waste. But pairing reduces the cost of mistakes constantly. What Gary was seeing was the countless times Jason or I would say “Let’s do.” only to have the other one say, “No, your forgetting about.” or “No, there's a better way.”. Finding dead code and deleting it.
DevelopMentor Courses - Saturday, April 30, 2011 - 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.
