This Week on C9: Live Wave 3, Coding4Fun - the book, Johnny Chung Lee, and Rise

The TED video is awesome. Thanks for that.

Very happy to see the Spec# release. Looking forward to giving it a run around this weekend.

I've often wondered how Microsoft measures the return on investment when it comes to things like Channel 9. Should the pointy nosed bean counters ever start pounding on Charles' and the rest of the 9er crew's doors demanding a blood sacrifice then I will happily get on a plane, come to the 'States and explain to them - with diagrams - why Channel 9 rocks and from my perspective represents the best outreach / programming community initiative I've experienced from Microsoft in 15 years of programming on Windows.

Best TED videos: Vilayanur Ramachandran on the brain and phantom limbs and Joshua Klein on crows. I can listen to Vilayanur's talk hundreds of times in a row, just because of his awesome accent.

That Vista Bridge API is a gift sent from the Gods. This has been frustrating me so much, and finally, a solution. Thanks for the link, guys.

Hey, that's hitting a little close to home. But, no worries, I'm hard headed. I still love you all!!!  Typing on the iPod a sucks a$$

Hehe... Of course. I literally LOL'ed when I saw it.

woah! does jonny work at microsoft?
charles, pleeease interview him

Cool video. BTW, I downloaded InnerTube and after a little bit of tewaking I was able to compile it, but can't get it to work. Anyone succeeded?

This is probably a stupid question, but how do you get the vertical line connecting the curly brackets in the c# editor? It shows in the coding4fun sample.

Hi Dan,

Thank you for helping out. I am using VS Express 2008. I added the SmartThread dll (v 1.0) and since I don't have (or want) an iTune library, I commented out its references. InnerTube seems to compile fine. I can launch it and it looks I can add feeds as needed, but when I click on refresh feeds the apps stops working (I get the Windows message "InnerTube has stopped working") and it exits. I could probably try debugging it, but my debugging skills are very basics.

Edit: i tried debugging and the code stops on file InnerTubeService.cs at line 202:

XmlTextReader xr = new XmlTextReader(wc.OpenRead(youTubeUrl));

The debugger says:

System.Net.WebException was unhandled by user code
  Message="The remote server returned an error: (400) Bad Request."
  Source="System"

Thanks for your help

Dan, Enjoy the read... and thank you for your help.

That works, thanks! I really need to learn some XML...

Silverlight 3? Hmmm. So if you're going to add a bunch of stuff to Silverlight I guess that means the target size for the redistributable is going to increase from the original 4Mb and therefore the excuse that you had to leave out this or that vital API because of size constraints is going to go away?

In which case, is there any chance that text layout could be fixed because it seems (at least to me, maybe someone knows better), that text layout is completely crippled in Silverlight 2.

When I saw that you only have Textblock but no FlowDocument and FlowDocumentPageViewer class in Silverlight 2, I figured that's OK, they don't want to bloat the download so they left it to the app developer to provide their own classes for doing layout that more complex than TextBlock can manage. Except you can't because there's no way to measure text. In particular the FormattedText class is absent from Silverlight. You can do some basic measurement by putting text one word at a time into a TextBlock object and reading back the ActualHeight/ActualWidth properties, but that doesn't help you much because you don't have other information needed for vertical layout such as the baseline. Important metrics are also missing from the FontFamily class.

Kindof sucks that a really important core class like FormattedText got left out when there are controls like DataGrid in the main install that could have been provided as a separate assembly for the few people that will use that instead of their own or a 3rd party control.
