Feel free to ask any questions you may still have, and I will get back with you as soon as I can. [...]

The way I see CacheMode in Silverlight

Ryan Plemons — Thu, 30 Sep 2010 04:29:20 +0000

If you have been doing any kind of Silverlight or WP7 work then you are probably already aware of a property called CacheMode on all of your controls. This magical little property can improve the speed of your applications by caching the visuals instead of redrawing them every time. This was EXTREMELY noticeable when I [...]

Wp7 Manifest validation fails?

Ryan Plemons — Wed, 22 Sep 2010 05:29:42 +0000

I just had the oddest error on a new project (nothing added by me) WP7 project. Manifest validation fails: Error code: ValidationInvalidAuthor . At least the error is semi descriptive, lets go check the manifest…. <?xml version="1.0" encoding="utf-8"?> <Deployment xmlns="http://schemas.microsoft.com/windowsphone/2009/deployment" AppPlatformVersion="7.0"> <App xmlns="" ProductID="{eb48b96b-98f1-4179-9d44-0c7541f756ee}" Title="DigitalTransfusion.Silverlight.Wp7.Project.Client" RuntimeType="Silverlight" Version="1.0.0.0" Genre="apps.normal" Author="DigitalTransfusion.Silverlight.Wp7.Project.Client author" Description="Sample description" Publisher="DigitalTransfusion.Silverlight.Wp7.Project.Client"> <IconPath IsRelative="true" [...]

Zero Gravity: Moving to WP7

Ryan Plemons — Mon, 20 Sep 2010 06:45:59 +0000

In a previous post I released the source code to Zero Gravity. In this post I am going to dive in and explain the changes that had to be made to make the game ready for Windows Phone 7. I was actually surprised at how little actually had to change considering the code was originally [...]

Zero Gravity: Conquering new frontiers

Ryan Plemons — Sun, 19 Sep 2010 19:18:14 +0000

It seems like only yesterday that Tim Heuer was showing off Zero Gravity and the lovable antics of Lt. Bennett. It is hard to believe that was over 3 years ago. The Silverlight platform has grown up by leaps and bounds in that amount of time, and with the looming release of Windows Phone 7, [...]

Silverlight Splash Screen Source fails to load my XAP

Ryan Plemons — Mon, 23 Aug 2010 04:51:04 +0000

It sounds like a pretty bold statement, but it is true. There is a way to break the built in Silverlight 4 splash screen loader. Most people will probably never see the problem. I only found this bug because the website I am building uses an Akamai caching network that was mis-configured. It was an [...]

IIS7 stops responding without an error

Ryan Plemons — Tue, 25 May 2010 01:41:52 +0000

One of the most maddening things in the world is when you have a problem with your application, but there isn’t an error code. Well recently I had such an error, and I hope I can save a few people from ripping out their hair. IIS7 appears to work correctly, but after loading a single [...]

Life without internet – is that even possible anymore?

Ryan Plemons — Fri, 30 Apr 2010 16:50:45 +0000

My blog posts have been delayed for the simple fact that I haven’t had internet for over a week (aside from my phone) Apparently my ISP had a serious problem that impacted the entire region. It took them a while, but they finally got to it. But, I just don’t have the patience to type [...]

Deep Zoom tutorial: Part 1

Ryan Plemons — Mon, 19 Apr 2010 00:30:19 +0000

What is Deep Zoom and how can it benefit my site? Traditionally whenever a website has a lot of images to share, they put up something called an “image gallery.” The images are usually placed in a grid (columns and rows), and there is usually some sort of paging. This works, but there are problems. [...]

it all begins with you

Ryan Plemons — Sat, 17 Apr 2010 05:15:15 +0000

My first few posts will be around deepzoom. How it works, the math involved, and will end with a fully functional module you all can use in your silverlight applications. I did a few applications that used deepzoom on very large image sets, and to say that the math involved was foreign to me is [...]
