Enhanced Touch Manipulations for Silverlight and Windows Phone

Following up on Jeff’s series on Touch Interfaces for Windows Phone, I wanted to show an additional technique that allows support for Manipulations in Silverlight. Furthermore, when this is extended to the Phone, it allows support for moving two or more UI elements independently, which as Jeff noted, is not possible with the Manipulation events…

Announcing Jounce 1.0 RTM – It’s here!

Jounce is the result of building composite Silverlight enterprise applications for a variety of verticals since Silverlight 3.0 and finding the common problems that needed to be solved.

Silverlight Scaling and Anti-Aliasing Issues

I recently had the opportunity to work on a rather nagging issue with a customer related to how Silverlight scales UI elements. The customer was kind enough to approve me posting the solution. The problem is with scaling UI elements on a canvas. The scenario is simple (and easy to reproduce). First, create a canvas…

Making Web Apps Sizzle with Bing Maps and HTML5’s Geolocation API

A few weeks ago, I wrote about Silverlight for Windows Phone’s location API, which allows applications to ascertain their location – latitude, longitude, altitude (if GPS is available), and so on. More recently, I’ve been writing samples around HTML5’s geolocation API. The two APIs are remarkably similar save for HTML5’s lack of support for setting…

Jounce Part 14: Using MEF for Non-Shared Views and View Models

Even if you don’t use Jounce, this post will help you better understand how to create non-shared views and view models with the Managed Extensibility Framework (MEF). The architecture I prefer in Silverlight is to keep a shared view and view model where possible. If only one instance of the view is visible at a…

Comodo SSL Certificate Breach’s Potential Impact on Security Token Services and their Identity Providers

Recently, Iranian crackers used a username and password to make certificate requests from the Comodo Certificate Authority. These requests were successful and certificates were issued for 9 domains which are published on the Comodo Fraud Incident Report page: http://www.comodo.com/Comodo-Fraud-Incident-2011-03-23.html This issue is of particular importance to me because SSL is the primary mechanism by which…

Clean Design-Time Friendly ViewModels: A Walkthrough

This is a quick walkthrough to demonstrate how to make what I call “clean” design-time view models. These are view models that provide design-time data for your application, but don’t embed that data in the final product. The release DLL and XAP files will only contain run-time support. First, fire up Visual Studio and create…

This blog post assumes that the reader knows the basics of Identity Providers and Security Token Services. Its purpose is to illustrate how to programmatically add Google or Yahoo as an Identity Provider because there isn’t much information available on how to do this.

Resumable downloads in Silverlight Out-Of-Browser applications

The task facing us is simple.  In fact, it has been done before.  Many download management tools already have the ability to resume downloading a file if, for some reason, the process was interrupted.  There is no built-in facility for resuming an interrupted download within a Silverlight applications.  Silverlight does provide some tools for working…

Silverlight for Windows Phone Programming Tip #8

One of the remarkable aspects of Windows Phone 7’s WebBrowser control is that you can build an entire Web site in isolated storage, point the WebBrowser control to it, and view the Web site on your phone. Once IE for Windows phones comes to support HTML5 (and that day can’t come soon enough, IMHO), this,…

Silverlight for Windows Phone Programming Tip #7

I recently worked on a phone project that required me to tombstone a MediaElement control. Basically, I needed to save the current playback position when the app was deactivated, and restore it when (and if) the app was reactivated. So I whipped up something like this:   protected override void OnNavigatedFrom(NavigationEventArgs e) {     this.State["Pos"]…
