Summary

The best way to show off a powerful new technology is to demonstrate real-world results with it, and that's exactly what Adobe and O'Reilly have done with Flex 3. Through it's Flex Cookbook website, Adobe invited users of the Flex 3 beta to post their own solutions for working with this technology, using O'Reilly's popular problem-solution-discussion format. Website monitors (and authors) Joshua Noble and Todd Anderson chose the most useful solutions for Flex 3 Cookbook. This highly practical book contains more than 200 proven recipes for developing interactive Rich Internet Applications and Web 2.0 sites, including several contributed by Noble, Anderson, and other Flex experts. You'll find everything from Flex basics and working with menus and controls, to methods for compiling, deploying, and configuring Flex applications.
