David Anson explains how improving Windows Phone 7 application performance is even easier after udating the LowProfileImageLoader and DeferredLoadListBox classes.

Source: Delay's Blog

I've continued to hear from people who are benefitting from LowProfileImageLoader and DeferredLoadListBox - and the code has even been incorporated into the WP7Contrib project! Along the way, I've also collected some great feedback, so I recently dedicated time to make a few improvements.

David Anson explains how to fix a problem with international keyboard layouts and TextBox-like WinForms classes.

There was a minor refresh for the Microsoft Web Platform last week; you can find a list of fixes and instructions for upgrading in this forum post. The most interesting change for the WPF community is probably the fix for a WebMatrix problem brought to my attention by @radicalbyte and @jabroersen where Ctrl+C, Ctrl+X, and Ctrl+V would suddenly stop working when an international keyboard layout was in use. Specifically, once one of the prefix keys (ex: apostrophe, tilde, etc.) was used to type an international character in the editor, WebMatrix's copy/cut/paste shortcuts would stop working until the application was restarted. As it happens, the Ribbon buttons for copy/cut/paste continued to work correctly - but the loss of keyboard shortcuts was pretty annoying. :(

David Anson has published this free PseudoLocalizer class which makes it easy to identify localization issues in WPF, Silverlight, and Windows Phone 7 applications.

Two posts ago, I explained the benefits of pseudo-localization and showed an easy way to implement it for WPF - then said I'd outline how to do the same for Silverlight and Windows Phone 7. In my previous post, I went off on the seeming diversion of implementing a PNG encoder for Silverlight. With this post, I'll fulfill my original promise and unify the previous two posts! As you'll see, the basic principles of my approach to WPF localization translate fairly directly to Silverlight - though some limitations in the latter platform make achieving the same result more difficult.

David Anson wrote his own PNG encoder and shares with you the source code, a simple test application and the automated test suite.

Okay, so what does a PNG (Portable Network Graphics) image encoder have to do with pseudo-localizing on the Silverlight platform? Almost nothing - except for the fact that I went above and beyond with my last post and showed how to pseudo-localize not just text, but images as well. It turns out the technique I used for that (reading the System.Drawing.Image instance from the resources class and manipulating its pixels before handing it off to the application) won't work on Silverlight.

The update that David Anson made to his BlobStoreApi adds container management, fragmented response handling, other improvements, and enhanced Amazon S3 support by Delay.Web.Helpers.

While I hadn't thought to get back to blobs quite so soon, finding out about the fragmented response issue kind of forced my hand. But all's well that ends well - I'm glad to have added container supported to Delay.Web.Helpers because that means it now has complete blob-related feature parity with the WindowsAzureStorage web helper and that seems like a Good Thing. What's more, I got confirmation that the Windows Azure Managed Library does not support Silverlight, so my BlobStoreApi is serving duty as an unofficial substitute for now.

In this blog post, David Anson explains how to localize a WP7 app that uses the Windows Phone Toolkit into different languages.

While it might be convenient if everybody spoke the same language (or communicated via telepathy), that's not the world we live in. :) Therefore, building applications that can be easily translated to other languages is an important consideration. Fortunately, it's easy - and it's covered in the MSDN article How to: Build a Localized Application for Windows Phone. But what's not covered is how to localize the controls in the Silverlight for Windows Phone Toolkit. As you might expect, it's fairly similar, but I've had a few people ask about this explicitly and I decided to do a quick post on the topic. As long as I was at it, I figured I'd show the entire process from start to finish just to make things a little easier...

David Anson updated the managed implementation of CRC32 and MD5 algorithms as well as posted the new release of ComputeFileHashes for Silverlight, WPF, and the command-line.

It feels like a long time since I last wrote about hash functions (though certain curmudgeonly coworkers would say not long enough!), and there were a few loose ends I've been meaning to deal with...

David Anson explains how DynamicOrientationChanges and TransitionFrame create a comprehensive transition experience for WP7.

Source: Delay's Blog

I've previously blogged about my implementation of AnimateOrientationChangesFrame, FadeOrientationChangesFrame, and HybridOrientationChangesFrame. As part of my DynamicOrientationChanges sample, these classes smoothly animate an application's layout transition as the phone orientation changes from portrait to landscape (and vice-versa).

David Anson is doing some testing of his SetterValueBindingHelper on Windows Phone 7.

Source: Delay's Blog

I've gotten a lot of great feedback from developers who have made use of SetterValueBindingHelper in their applications. I've found it quite helpful in my own projects, and I'm glad many of you have, too! With today's announcement, I hope another "generation" is able to use SetterValueBindingHelper to benefit from the many advantages of the Silverlight platform's rich data-binding support.
