MediaElement and Visual Tree

by Corrado Cavalli via Corrado's BLogs on 3/7/2010 7:01:22 AM

Sto lavorando su un applicazione Silverlight che, tra le varie funzionalità, deve eseguire il play di streams in formato .wma e per questo requisito la scelta cade automaticamente sulla classe MediaElement. Convinto della banalità della cosa ho scritto qualcosa tipo: MediaElement me = new MediaElement(); me.Source = new Uri("http://thesite.com/stream.wma", UriKind.Absolute); me.Play(); per scoprire che non funziona, ho quindi rimediato usando: WebClient wc = new ...

Learning the M-V-VM pattern for XAML development

by Tim Heuer via Method ~ of ~ failed by Tim Heuer on 3/4/2010 9:17:04 PM

Quick, what’s the most popular thing in XAML development?  Yeah, thought so…MVVM or Model-View-ViewModel. It’s one of the most popular subjects I hear about when people talk about developing applications with WPF and Silverlight.  However, as much as it is talked about and as much as frameworks are born every day, there isn’t a ton of just simplified ‘here’s how you do it’ information in one place.  I mean, sure there *is* information, but I have to admit I think it is a bit scattered all over. ...

by jesseliberty via Jesse Liberty - Silverlight Geek on 2/26/2010 5:14:42 PM

This mini-tutorial is part of the SLHVP documentation   One of the goals of the Silverlight HyperVideo Project is to demonstrate best practices.  So when is it okay to throw in a quick hack to get things working? Case in point: as I approached the release this week for the latest alpha,  I noted that the player was not updating when the user clicked on a topic, though the links were appearing as if  the player had been advanced. To make the issue clear, in this image ...
