Flex is a very powerful and versatile technology for creating web application front-ends. But what every good web application needs is a robust data source, be it XML, or a database. Flex is very adaptable in terms of connecting to data sources, and that is the main focus of this book. In Foundation Flex for Developers, Sas Jacobs assumes that you've got the basics of Flex down already, and 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 detailcreating custom components, user and web browser interactions, binding, formatting, and validating data, debugging, and more. In the second half of the book, the focus is 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.

• Covers Flex application basics
• Covers connecting Flex 2 and Flex 3 to a variety of Data Sources
• Includes several complete case studies.

Laszlo in Action is the first comprehensive guide to the Laszlo system and its language LZX. OpenLaszlo is an increasingly popular open-source platform for the development and delivery of rich internet applications across multiple platforms: Flash, DHTML, and J2ME. The dramatic emergence of Ajax over the past year was a first step in the transition from page-oriented HTML web applications towards more full-featured rich internet applications. OpenLaszlo provides another important step in this continuing evolutionary process through the increased productivity resulting from LZX's declarative approach. It provides developers with the tools to create web-based applications offering the usability and interactivity associated with desktop applications, and the low costs associated with web-based deployment. The cross-platform nature of Laszlo LZX applications allows source code with only minimum modifications to run natively on all popular web browsers, on all desktop operating systems, on the Flash platform, and other platforms in the future. Written to address the needs of a wide spectrum of developers, ranging from client-side HTML and JavaScript developers all the way to enterprise-class Java or Rails engineers, this book provides a very hands-on approach towards building applications that solve real-world problems across both the Flash and DHTML platforms. Starting with the fundamentals of Laszlo LZX, the authors quickly move towards applying this knowledge to the design and development of a full-scale application called the Laszlo Market. This provides a working context to assist understanding the underlying concepts of Laszlo LZX and, more importantly, how to apply this knowledge in innovative ways. The construction of the Laszlo Market proceeds over the course of the book illustrating topics starting with an initial wireframe and storyboard design to optimization issues dealing with the application's deployment across the Flash and DHTML platforms.

Flexible Rails is a unique, application-based guide for using Ruby on Rails 2 and Adobe Flex 3 to build rich Internet applications (RIAs). It is not an exhaustive Ruby on Rails or Flex reference. Instead, it is an extensive tutorial in which the reader builds multiple iterations of an interesting RIA using Flex and Rails together. Author Peter Armstrong walks readers through eleven iterations in which the sample application–pomodo–is variously built, refactored, debugged, sliced, diced and otherwise explored from every conceivable angle with respect to Ruby on Rails and Adobe Flex. The book unfolds both the application and the Flex-on-Rails approach side-by-side.

As a Flex developer, you'll no doubt come across repetitive problems every day in your workwouldn't it be nice to have a library of solutions to turn to, to solve these problems quickly and easily? Well, this book provides just that, with over 100 solutions to common problems in one easy volume. In Flex 2 Solutions, renowned Flash and Flex expert Marco Casario assumes you know the basics, and dives straight into practical code examples that you could build up yourselves via step by step tutorials, and plug straight in to your own code, saving you hours of development time. Areas explored include Flex 2 components, charting, working with remote data, data validation, displaying data with list based controls, controlling the look and feel of your applications, application security, working with dynamic data sources (such as ColdFusion, PHP, and Java backends,) and much more. In each solution, Marco takes you through the workings of the example step by step, and then presents some expert's tips, which will take your understanding further, and give you unique insights into Flex development.

• Over 100 Solutions to common problems included
• Plug the code example straight into your own applications, saving hours of development time
• Covers the full spectrum of Flex 2 topics, from styling your applications, to security, and interfacing with databases.

This book is for any Flex developer who has mastered the basics, but wants to take their skills to the top levelit is packed with essential practical techniques in use in a professional production environment, which you can learn from and use in your own Flex 2 or Flex 3 applications. Written by a team of expert developers from the Los Angeles-based Almer/Blank consultancy, the book takes you through exactly how they built the popular Rich Media X (RMX) application for Adobe user groups, step by step. Assuming the basics, they take you through planning the project, wireframing and application design, putting the basic structure together (including the PHP and MySQL backend,) customizing the look and feel of the application (to make it not just look like any other Flex application,) and implementing all the killer features that make the RMX great, such as blog, wiki, content aggregation from RSS and other sources, video, audio visualizer, events calendar, and advertising mechanisms.

• Learn how Rich Media X was built!
• A real-world Flex book, written by experts using the technology in their day-to-day work
• Contains all the killer features you need to build up your own web 2.0 Flex applicationblog, wiki, video, content aggregation, events calendar, and much more.
