In Foundation Flex for Developers, Sas Jacobs explores in detail how to create professional data-centric Flex 2 and Flex 3 applications. In the first half of the book, she starts off with a brief exploration of Flex and ActionScript 3.0, before looking at application essentials in detail, including creating custom components, user and web browser interactions, binding, formatting and validating data, debugging, and more. The second half of the book focuses on connecting Flex to data sources and covers XML, Flex Data Services, PHP, ASP.NET, and ColdFusion in detail, via a series of step-by-step case studies.

This book details how to customize the look and feel of Flex applications. It takes you through how to customize style and layouts using CSS; how to bring design assets into Flex from applications such as Photoshop, Illustrator, Fireworks, and Flash; how to spice up your design work with some handy ActionScript 3.0 techniques; and even a look forward to designing hybrid desktop/web applications with Flex and AIR. It culminates with several design-oriented case studies, including a video picker application, picture gallery, customer service site, and more.

XML is the lingua franca of the Web. All designers and developers working in a web environment need a sound understanding of XML and its role in application development. Many software packages and organizations allow for the exchange of data using an XML format. Web services and RSS feeds are now commonplace. For those working with Flash and Flex, a thorough understanding of XML is particularly important. XML documents are one option for the data provided to SWF applications. Flash and Flex can load, display, and modify XML content. These applications can also send XML content to other applications for updating or for use in different situations. ActionScript 3.0 introduced some fundamental changes to the way in which Flash and Flex applications work with XML. One significant change is that XML is now a native data type. ActionScript 3.0 also introduced new classes and a different framework for working with external documents. These changes are based on the E4X ECMAScript standard, and they streamline and simplify the process for working with XML in Flash and Flex. In Foundation XML and E4X for Flash and Flex, Sas Jacobs gives you an introduction to XML and E4X. She explores the XML and XMLList classes and explains E4X expressions, providing examples for both Flash and Flex. In addition to explaining how to incorporate XML documents in Shockwave Flash applications, Sas shows you approaches specific to Flash and Flex and explores real-world usage. The book finishes with two case studies. In the first, you will learn how to consume and display information and images from Flickr using Flash. In the second, you will work with Adobe Kuler in Flex. Whether you are a designer or developer, this book will help you work with XML and make the transition from ActionScript 2.0 to ActionScript 3.0. It will also provide you with an excellent grounding if you are new to Flash and Flex.

If you want to try your hand at developing rich Internet applications with Adobe's Flex 3, and already have experience with frameworks such as .NET or Java, this is the ideal book to get you started. Programming Flex 3 gives you a solid understanding of Flex 3's core concepts, and valuable insight into how, why, and when to use specific Flex features. Numerous examples and sample code demonstrate ways to build complete, functional applications for the Web, using the free Flex SDK, and RIAs for the desktop, using Adobe AIR. This book is an excellent companion to Adobe's Flex 3 reference documentation. With this book, you will: Learn the underlying details of the Flex framework Program with MXML and ActionScript Arrange the layout and deal with UI components Work with media Manage state for applications and components Use transitions and effects Debug your Flex applications Create custom components Embed Flex applications in web browsers Build AIR applications for the desktop Flex 3 will put you at the forefront of the RIA revolution on both the Web and the desktop. Programming Flex 3 will help you get the most from this amazing and sophisticated technology.

We all know what a great tool Flash is for creating dynamic, engaging web content, and Adobe's CS4 release just makes it even better. Among the newer features is the ability to take all the power of Flash for the Web and put in on the desktop using AIR. AIR capability is built right into the Flash CS4 integrated development environment, which means you can start writing desktop applications right away. This book not only covers the essentials of using Flash with AIR (and AIR with Flash), but also shows you how to extend application functionality in new ways. Once you've got Flash on the desktop, you're no longer constrained by the limitations of running inside a web browser. You'll have access to the local desktop file system, and AIR adds SQLite functionality for native database support. And just as Flash animations have a consistent look and feel across browsers, AIR allows you to create applications that work consistently across operating systems—Mac OS X, Windows, and Linux. For any Flash developer who wants to go from the Web to the desktop (and who doesn't?), this book is required reading. It not only tells you how to do it, but is full of practical, easy-to-follow examples that will have you building desktop AIR applications with Flash in no time. Expanding your existing Flash skills with the Essential Guide to Flash CS4 AIR Development will make you an even more potent and indispensable force on any development team!

Keep ahead of the game and get up to speed with Flex 3, Flex Builder 3, and ActionScript 3.0, with this comprehensive guide. Expert Flash trainer Charles Brown first takes you through the basics of installation and the Flex Builder environment. He then teaches you all the essentials of MXML and ActionScript 3.0, such as containers, states, and events, before moving on to more advanced topics like interfacing Flex with ColdFusion and .NET, creating Flex components with Flash, and much more. No matter what level you were to start with, by the end of the book you'll be creating powerful Flex applications.

If you want to use Adobe Flex to build production-quality Rich Internet Applications for the enterprise, this groundbreaking book shows you exactly what's required.
