Object-oriented programming (OOP) is something that is usually considered a black art for hardcore programmers, not a topic of conversation for Flash developers. However, when adobe introduced ActionScript 3.0 to the mix, it changed everything. ActionScript 3.0 is much more powerful than previous versions, allowing Flash developers to produce robust object-oriented applications. But with that power comes great responsibility--OOP is now a requirement, rather than optional, and there are new things to learn. This book, based on the ever-popular Object-Oriented ActionScript for Flash 8, provides you all you need to delve into the world of OOP with confidence, whether you are using the Flash IDE, Flex builder, or even command-line tools for your development work. First, you are taken gently through all the principles of OOP that you need to know, and then given a guide to designing and implementing applications in ActionScript 3.0. Next, we step up a gear, showing you the Flex builder development environment and teaching about creating reusable, extensible component frameworks, manager classes, animation and effects classes, UI widgets, and more. lastly, we look at some more advanced topics such as communication between Flash and the browser and Web services. case studies are included that apply the knowledge presented, giving you real-world projects to learn from and adapt for use in your own work. Mastering object-oriented programming is essential for modern Flash development, and Object-Oriented ActionScript 3.0 is the only guide you'll need.

This book gives the most up-to-date picture of the topic-XML support in the most modern web browsers, creating XML-driven applications using the most versions of web standards and server-side languages, including CSS 2.1/3, DOM, XSLT and XPath 2, PHP 5, ASP.NET 2, and many more. The book shows that you can give the reader all they need to know to hit the ground running, without making them trawl through hundreds of pages of syntax. The book also provides an introduction to Ajax-style programming, which is an essential topic for modern web developers to understand. XML is core to Ajax, so an understanding of it is essential when learning how to program Ajax functionality. This book therefore provides a great stepping stone for readers wishing to take this path.

XML is a completely platform agnostic data medium. Flash is able to make use of XML data, which is very useful when you are creating Rich Internet Applications &emdash; it allows you to populate Flash web interfaces with data from pretty much any source that supports XML as a data medium, be it databases, raw XML files, or more excitingly, .Net applications, web services, and even Microsoft Office applications such as Excel and Word! In this book, Sas Jacobs first introduces XML itselfwhat it is, its syntax, its associated technologies (such as CSS and XSLT, ) and how to get XML out of your applications in a format Flash can use. Then she shows how to use the XML object to stream XML data into Flash, and how to use the XMLConnector component and XML Sockets to build advanced Flash/XML applications. Numerous example applications are built throughout the book, including an MP3 player, XML photo gallery, an Excel-driven web catalog, Access and Word-driven content management systems, and an XML-driven chat application.

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 Flashapplications, 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.

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, author 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, LiveCycle 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 What you'll learn How to create custom components How to handle user and web browser interactions How to debug Flex 2 applications How to bind, format, and validate data How to load and write external content The essentials of XML, and working with it in Flex 2, including E4X The essentials of Flex Data Services How to build up data-driven Flex 2 applications with PHP, ASP.NET, and ColdFusion backends Who this book is for

This book is for any Flex developer who knows the basics of building Flex user interfaces, and wants to learn how to connect their applications to data sources.
