In Flex 3 Beyond the Basics, David Gassner delves into advanced Flex development skills, including custom popup windows and programmatic animation; parsing XML with E4X; and integrating Flex applications with ColdFusion, ASP.NET, and PHP. He explores effective ways to use Flash and Flex together, including the exchange of graphical skins, symbols, and components. David also demonstrates how to localize a Flex application. This course is a follow-up to Flex 3 Essential Training, and some experience with ActionScript 3, Flex Builder, and the Flex 3 Framework is recommended. Example files accompany the course.
