Is there an easier way to build and deliver rich internet applications (RIAs) other than the Flash IDE or Ajax? Absolutely. With Adobe Flex 2, the Flex 2 SDK, and this book, you have all you need to build RIAs. Programming Flex 2 offers you plenty of practical and useful examples that reveal how and why to use a particular feature of Flex 2, and when and when not to.As part of the Adobe Developer Library, Programming Flex 2 is the authoritative guide to this new Adobe framework. You learn to use a markup language called MXML and a vast library of off-the-shelf and highly-configurable components to build Flash-based applications that combine the immediacy of the Web with the functionality and responsiveness of desktop applications. You also discover why - with the Flash Player runtime environment and the powerful ActionScript 3.0 programming language - the possibilities with Flex 2 are nearly limitless.
