Look ma, I'm famous...Flash.NET
If you check out this book on the UK Amazon site, you'll see my name on it! Woohoo! If you find this same book on the US Amazon site, you won't see my name on it! :(
Originally I had written a case study (not even a whole chapter) for the book that was about 60 pages long. It basically walked you through setting up an admin section for your site that could administer all the users, by passing user objects to and from flash to and from a .NET WebService. I thought it was pretty decent, but after the second round of editing they said it had been canned along with a couple other chapters, because the book was too huge and they were already over budget (this is Friends of Ed, mind you, a sister company to the now dead, Wrox ;)). So I got paid and was never allowed to send out my chapter anywhere...what a bummer!
Anywho, I've talked with a bunch of people about the book and it seems to be a pretty good one. Flash Remoting, which is what a large chunk of the book is about, is a nice little service that sits on your web server and handles web service requests for you (since flash can't handle them natively) and transforms any results from the webservice into native actionscript objects. It's really neato and if you're into Flash and WebServices, it's a great way to use them together, so you can have yet another UI on top of your WebServices. DonXML would probably kill me for saying this, but one of the reasons it's so great is because you never have to touch any XML! ;)
Again, as I mentioned before, I am a moderator for the Flash Remoting section of one of the bigger online flash communities out there, We're Here. So drop on by if you have any questions about it!
