I've recently picked up a great book called Flash Math Creativity . I been inspired by some of the techniques it outlines and have played around with similar ideas in WPF. The exercise has been a fruitful one, in that I'm making some pleasing computer...

At this point, with the amount of great content online (and free), it is possible to train yourself on WPF. But where to begin? There are a ton of links, blogs, documents, screencasts, videos and more -- so much, in fact, that beginning can be daunting...

(Updated 6/21) -- Please go check out http://flotzam.com which is the released incarnation of this software! I just posted the screen saver source to Flitter here . It is now entirely configurable, both for Flickr and Twitter. To install, right...

I recently needed to create a full trust .xbap application on the November CTP. As you may know, Avalon Web Browser applications run in a sandbox, which allows them to be installed without any security prompts. However, there are cases, such as intranet...

If you are following Vista, you are probably aware of the Sidebar, real estate on the desktop that can be used to host gadgets. And, if you are aware of Sidebar, you might be aware that the platform for gadgets is DHTML + Javascript. And, if you are a...

If you would like to install Monad on XP or Win2k3, you can do that by following these instructions: 1. Acquire a passport account 2. http://beta.microsoft.com 3. Logon using the guest ID ‘mshPDC’ 4. Register using the registration...

The Woodgrove Finance Application is a great demo of how WPF can be used to create better data visualization, in this case for financial data. I've posted the source code -- there are some good nuggets in here worth exploring. Click Here To Run...

In my earlier post , I talked about WPF in the Sidebar by using the IFRAME to host XBAPs. In this post, I'll talk about another technique: using ActiveX. For an in depth discussion of using ActiveX in gadgets, see Jaime Rodriguez's blog post . He's got...

I just discovered the HierarchicalDataTemplate , which is basically a DataTemplate that can recursively walk a tree. Once again, I'm blown away by how Avalon databinding works. The HierarchicalDataTemplate derives from DataTemplate , but adds an ItemsSource...

Andrew Whiddett is a developer at REZN8 , an amazing interactive design firm. REZN8 built the Netflix demo that was shown at PDC05. Andrew doesn't have a blog and asked me to be a proxy for a code sample he wrote, which I was more than obliged to do!...

If you haven't seen, the February CTP of WinFX is live. Be sure to check out the release notes if you are having install/uninstall issues . Below is an incomplete list of breaking changes: 1) The following XML namespace Uris are modified: OLD...

I just posted three new hands-on labs for Expression Blend that were created for MIX but haven't been posted for the world yet. There's lots of little nuggets in there worth checking out, things like creating a user controls, databinding, triggers, styling...

If you are doing development of browser-hosted .xbap WPF applications, there can be some confusion and delay when you want to clear out the cache. If you have the .NET SDK on the machine, you can run the mage program with the following switch: mage...

One area that is currently top of mind for me is designer and developer collaboration with WPF and Expression Blend, in particular around animation. I'd like to start documenting some techniques and outlining things that can and can't be done. Before...

I've been meaning to document how I wrapped the Twitter API ... in 4.5 seconds. There is a very powerful feature in .NET is a tool in the sdk called xsd.exe . Darren David actually has a fabulous post on exactly the power of this tool: never touch a DOM...

With Daniel Lehenbauer starting a nifty GotDotNet 3dTools project and with Mike Hodnick writing a great tutorial about WPF 3D that references my out-of-date Sandbox3D project, I finally ported Sandbox3D to the Jan CTP. I was able to get rid of a ton...

There are a handful of new features in Beta 2 and lots of performance tweaks and bug fixes. My favorite new feature: the ZIndex property! Hooray! Anyone who has dabbled with WPF even remotely has requested this feature and now we have it -- an attached...

So there is this contradiction that many people have when they first dig into WPF. Let's take a hypothetical developer. Let's call the developer Jane. She attends a conference or goes to a user group meeting and gets interested in WPF. She reads the literature...

Tim Sneath has been doing a great job of blogging the many Vista/WPF showcase applications that are being deployed right now. If you are looking for a quick list of URLs that you can hit for the .XBAP or .APPLICATION files, please go to the WPF Application...

So MIX06 may be old news, but it is still fresh in my mind. I took a week off after the show but now I'm back and fired up! The show itself was great (and not just because it was in Las Vegas). I can finally talk about what I've been up to for the last...

Okay, here's the scerario: You've got a bunch of constants in your code in a static class that you want to reference in your XAML files. How do you do it? {x:Static} to the rescue! Simple and very handy, although not particularly intuitive or well documented...

My next inspiration from the algorithms introduced in Flash Math Creativity was based on the work of Jamie MacDonald . In looking at his work, I quickly realized that I was going to need to brush up on my trigonometry skills. This led me to another great...

New in the September CTP is the ScreenSpaceLines3D class in System.Windows.Media.Media3D. This class is functionally a line primitive. Syntax-wise, it is quite easy to use. Here is an example: <ScreenSpaceLines3D Color="Black" Thickness="4.0" Points...

There is a great 3D cloth demo that has been floating around interally for awhile and shown at conferences, talks, channel 9 interviews, etc. However, we haven't ever posted the source code . . . until now. You can run it from here and download the source...
