Microsoft’s PivotViewer control is an amazing tool for visualizing data and creating a unique UI for your application. The one issue everyone seems to have with it, however, is its lack of styling capability. In fact, working with PivotViewer in Expression Blend yields little in the way of styling or templating. There are only a few color settings one can make, and some generic overall changes. Replacing the filter panel or info panel is not currently supported. Wh ...

As is often the case when big events happen, sometimes some important announcements can get overlooked and/or overshadowed. Mix 2011 certainly featured big news, including Silverlight 5 Beta, the Windows Phone 7.5 features, IE10, and the latest in the MVC framework. However, in all of the hoopla, the release of the SP1 refresh of the Microsoft Visual Studio Async CTP SP1 Refresh, as well as some of the important changes, may have gone unnoticed. There are a few important things to n ...

The first beta of Silverlight 5 was announced at MIX this week and is available for downloading. As such, I’ll be blogging about the new features in weeks to come. I’ll also be delivering sessions on Silverlight 5 at several upcoming conferences, including Microsoft TechDays in Belgium, Microsoft DevDays in the Netherlands, Devscovery in Redmond, WA, and Microsoft TechEd in Atlanta. If you plan to attend any of those conferences, I’d love to see you in my sessions! One of the most exciting feat ...

Using a memory profiling tool such as ANTS Memory Profiler from Red-Gate or MemProfiler from SciTech Software (I’m sure there others, but those were the only two I found that can profile a Silverlight Out-Of-Browser application) is a good idea. By using such a tool, developers can discover a myriad of memory leaks and fix them before releasing their code. These leaks usually stem from classes that attach event handlers to other classes. In fact, in my opinion, I’ve seen more me ...

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 movement thresholds. Both allow you to write location-aware apps with remarkably little code, and both can be combined with Bing Maps to produce stun ...

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 integrity and confidentiality are assured for security Security Tokens and Securit ...

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. For further information about using the ManagementServices proxy, I suggest downloading the Codeplex ACS Management examples from http://acs.codeplex.com/releases/view/57595 We manage the Windows Azure AppFabric Access Control Se ...

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, I believe, will be a useful mechanism for packaging HTML5 apps so that they look and feel like native phone apps. Even now, using a WebBrowser control as a window into local HTML content provide ...

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"] = Player.Position; } protected override void OnNavigatedTo(NavigationEventArgs e)

In a few editions of my book, I showed how to implement weak event handlers which allow an object to be GCd if no other reference is keeping the object alive. If the object is alive, it recieves the event notification and if it isn’t alive, it doesn’t receive the event notification. It has come to my attention that the code I show in my book is incorrect and does not work as advertised. I have corrected that code and the working version is shown below: public static class WeakEventHandler { & ...

One of the exciting new features coming in HTML5 – and one that works in most HTML5 browsers today – is Web storage. The latest draft of the specification defines two types of Web storage: local storage and session storage. Local storage, which is analogous to isolated storage in Silverlight, persists data across browser sessions, and does it purely on the client side. It provides an easy-to-use mechanism for storing arbitrary data on the client and is a cost-efficient alternative to cookies. Se ...

The last five years of my career have been devoted to Silverlight. I began working with it long before version 1.0 was released, and with Silverlight 5 on the horizon, I’m even more excited about it today than I was then. The fact that you can write phone apps with it is icing on the cake and the number one reason I’m bullish about Silverlight’s future and about the long-term prospects for Windows phones. I am honored and privileged to teach Silverlight and Silverlight for Windows Phone to Micro ...

Codestock is an amazing event that I first attended last year in Knoxville, Tennessee. It's hosted at a great venue in a wonderful city and loaded with exciting sessions. I had just as much fun speaking at my session as I did attending the other sessions and learning about new technologies. I've submitted two talks this year and if you are planning on coming and are interested in these topics, please cast your vote. Codestock, unlike other venues, gives priority voting to those who have register ...

I love computing technologies. I've been programming since 1975 and experimenting with various languages (Basic, Pascal, COBOL, FORTRAN, RPG, APL, C, C++, C#, a little Python) and platforms (mostly DOS, Windows, .NET Framework and Android). During these years, I've consulted, published books, published magazine articles, and produced classes to help others work with these some of the more popular of these technologies. To this day, I've kept up with many of these technologies and I will certainl ...

Scope Your SIP - sounds painful, doesn't it? Adding on to Jeff's series concerning WP7 Silverlight development tips, I figured it worthwhile to add another one. The SIP is the Software Input Panel – AKA the Phone's onscreen keyboard. One of the handy features of the SIP is the ability to customize it to fit the needs of the textbox it is being displayed for – eg if you need to enter a phone number, why wrestle with a bunch of letter keys?Figure 1- SIP default appearance (USA)To ...

In Part 1 of this series, we built a basic photo-extras application that allows a user to load photos from the phone’s Pictures library and convert the photos to grayscale. We also learned that in the absence of tombstoning support, the app doesn’t work very well. Specifically, if the user clicks the Start button to tombstone the app, followed by the Back button to reactivate it, the app loses its state. Any photo that has been loaded simply goes away. We can fix that by adding tombstoning supp ...

With all due respect to Steve Martin's hilarious portrayal of Navin R. Johnson and his quest for "his special purpose" in 1979's The Jerk. Tonight Microsoft released the Windows Phone Developer Tools January 2011 Update, which can be downloaded here. In addition to the content in the new tools, there's also some interesting other news concerning the availability of unsubsidized phones for purchase at Zones.com.The New ToolsThe big update item is the addition of Copy & Paste funct ...
