My favorite conference of the year is approaching fast! MIX10 is shaping up to be a fantastic conference yet again. If you have attended MIX in prior years you know how the people and conversations found at MIX are top notch, rewarding and just a lot of fun. One of most memorable times at MIX09 is just the time I hung out in the common room where it seems everyone gathers before, during and after sessions. The keynote, sessions and speakers are all top notch and the after parties are not to be m ...

This week I decided to experiment with a few webcam features and put together an application that activates a webcam, allows the user to take snapshots, and save the snapshots to PNG files. I like when demos use MVVM out of the box instead of just throwing all of the code in a single code behind, so one of my goals was to make a passing effort to break the code out and use MVVM practices. The first thing I did was grab Tim Heuer’s webcam sample which already handles activating the webcam. Tim d ...

The common technique many developers use to debug Silverlight Out of Browser applications is to attach the debugger to the SLLauncher.exe process. However, there is a another way to debug installed OoB apps. Attaching to the process does not allow you to catch and debug any startup code however this technique below does allow you to do so. If you are running a Silverlight 4 beta application hosted in a web project, here are the steps to debug when in OoB mode. Set the Web project that hosts ...

One of the new features of Silverlight 4 Beta is the addition of the IDataErrorInfo interface. In Silverlight 3 we throw exceptions when a property value is invalid. The IDataErrorInfo interface has been around in .NET but is new to Silverlight 4 beta. It allows you to invalidate property values without throwing exceptions. Implementing this interface is pretty straightforward, though there are several ways to do it. To help you get jumpstarted with this new feature, I included some sample cod ...

Are you planning on attending VSLive Orlando this week? If so, please stop by the 3 sessions I will be presenting at VSLive Orlando and say hi. I really enjoy speaking at the conferences and getting the chance to have great conversations with all the people.

My latest Data Points column is now online and in print in the October 2009 issue of MSDN Magazine. The column’s title is “Validation with Silverlight 3 and the DataForm” which focuses on the validation features in Silverlight 3. This includes the DataForm, the validation XAML binding attributes, and the DataAnnotations. Code alert: I’ve been made aware that the code for the article linked to in the online version may not be valid at this time. So for now you can download the code form my site ...

I recently wrote an article that demonstrates how to use the DataForm and validate data entry in Silverlight using the DataAnnotations. One of the pet peeves I have with the validation is that it throws in exception in the setter of your public property. Putting my disagreements with that aside for a second, it causes a major inconvenience when debugging the application. For example, when running the application that uses the DataAnnotations and one of the conditions is violated, the debugger wi ...

Model-View-ViewModel (better known by its super hero alias of MVVM ) is a great pattern to use with Silverlight and WPF. Here is my 5 minute perspective on MVVM (yep, it took me 5 minutes to spit this out too, so please be kind on any typos :-) ) One of the things that can be frustrating with any pattern is the immediate assumption that many articles have that everyone knows what MVVM means. This post is intended to be a short, quick, and hopefully easy explanation of MVVM. Another interesting ...

Anyone who knows me well knows that I can’t help but get myself into more activities than I probably have time for. Lately I’ve been working hard to fill a need that I feel exists in the Silverlight community. The goal of this effort it to self enable the community and to connect people with some of the very best code samples and tips out there. I am working with some of the best Silverlight minds out there (both in and outside of Microsoft) to get this site together and add content to it. I am ...

A bit late to the party here, but I finally got around to re-reading Jeff Paries Silverlight 2 Animation book. I met Jeff at MIX 09 and talked to him at the Silverlight MIXer party. I also attended his presentation at MIX on animation … the guy is very very good. I had a copy of his book on my desk or review along with about 20 others. I read his book back in April over a weekend. It is very well written with a lot of great examples that take you step by step through animations. In short, ...

Last week I posted the code for a swivel behavior I created. It rotates a set of panels 180 degrees. The next step in the rotation process is to add a button that causes the rotation from front to back and then from back to front. This post will talk about how to create a button that does this rotation. Here is the final result … First, I created a copy of my panel demo page from my previous post. I removed my Swivel behavior that I used in the pre ...

A while back I created a pair of Storyboards that make a pair of panels swivel to show a front side and a back side. The key ingredients in the storyboards are: Plane Projection using Perspective 3D Easing Visibility (Opacity can be used instead if you prefer) Easing and 3D features are new to Silverlight 3 but really give it a nice effect. The easing makes it start slowly, then appear faster at the 90 degree turn, and then ease out. Storyboard The storyboards are not that invo ...

I updated my SilverTwit code for my June 2009 Data Points column in MSDN Magazine to use the release version of Silverlight 3. The revised code can be retrieved in the codeplex site here. There were 3 sets of changes: (1) Twitter started using larger numbers for Ids, so I had to switch to use long instead of int and (2) the API for Out of Browser applications changed from beta to release and (3) the Out of Browser settings (formerly in the AppManifest.xml) changed. Here are the changes since I ...

Lately I have been immersed in the world of MVVM/Silverlight and often Prism. But in this world the design elements can’t be pushed aside. I admit it … I am a developer who has fallen in love with Blend! So I was pretty unhappy (Ok, I was very frustrated) when I started using Prism apps and breaking the apps into separate decoupled modules and found that Blend could not see the resources at design time. Basically, I usually have a handful of projects (modules) and they are completely decoupled f ...

I’ve been working on fine tuning a Silverlight progress control for an article with Simple-Talk.com. Along the way I wanted to create a background that dims the entire page while the progress control is up and running. Easy stuff … just stick it in a Grid panel with HorizontalAlignment and VerticalAlignment set to Stretch. Works like a charm … except when it doesn’t :) Enter regions in Prism … they are a very cool concept, kind of like a special zone in your app where you can place Views. In th ...

If you work with Silverlight a lot like I do, you might be frustrated with the time it takes Visual Studio to try to render the preview of your Silverlight Views. This can be a painful process, especially when the View gets more complicated … because sometimes Visual Studio cannot even display the preview. Also, whenever the XAML page is opened in Visual Studio, it takes a while to "try" to display the View in preview mode. There really is no value in the preview mode (aka Cider) wit ...

My Data Points column in the June 2009 issue of MSDN Magazine is now online. In this issue I demonstrate how to build an out of browser application using Silverlight 3 and demonstrate how the API works under different circumstances. I demonstrate the features using a Silverlight Twitter client (a light weight client I might add) that uses offline storage of data when the app is offline, and it also displays the network status.
