ActionScript 3.0, the Flash Platform's scripting language, offers a lot of new and powerful features. ActionScript is now a full-fledged programming language, with complete object-oriented capabilities, improved event handling, sound and video support, drawing capabilities, support for regular expressions, and much more.
Whether you are a Flash designer wishing to add to your skill set or an experienced ActionScript developer who wants to get up to speed with the latest version, you'll find all you need to know in Foundation ActionScript 3.0 with Flash CS3 and Flex.
This book covers all the essential techniques from the ground up, allowing you to get up and running quickly and easily. Starting with the fundamentals, you'll learn about using ActionScript objects, manipulating sound and video, and harnessing the power of regular expressions and XML.
The book concludes with two case studies to consolidate what you've learned and to introduce some more advanced techniques. This will give you some grounding in the new and exciting world of ActionScript 3.0 and show you how it all fits together in larger applications, allowing you to go on and build your own professional sites.
The sensible layout of the book makes it easy to find information about specific techniques. It doesn't aim to be an exhaustive reference, but rather focuses on the essential skills that will enable you to get up and running more quickly. With this book as your guide, you'll be creating killer Flash applications before you know it!
This book examines all the avenues open to professional or aspiring professional Flash MX designers. It takes a look at advanced uses of the new MX features, such as components and the Drawing API, and gives guidance on building whole new structures for animation, Dynamic Content, PHP, ColdFusion MX, XML, video, audio and audiovisual formats.
Never before has so much power been so accessible to the web designer. This book is designed to put that power in your hands.
Flash MX Studio has been broken into four sections to address the most common needs for the Flash designer. First off, Jamie McDonald provides five chapters on site presentation and the principles of web design. These opening chapters take a look at how to create slick, professional-level sites, involving Flash MX's new drawing and motion capabilities and interactive techniques.
The second section concentrates on ActionScript. Flash's resident coding environment is crucial to master, and taps into Flash's great strength—intuitive and interactive applications. Keith Peters and Todd Yard have buddied up on this section, and examine some of the most advanced ActionScript techniques around. Be warned—this section is not for the faint-hearted!
Section three takes a look at Flash MX's greatly improved visual, audio and audiovisual capabilities. Its three chapters, written by Jez Turner and Alex White, concentrate on building a single site aimed at displaying rich media content.
The final section is devoted to expounding a few myths about dynamic content using Flash. Its four chapters talk about general practice, before focusing in on specific areas, including introductions to PHP and XML, together with a look at Macromedia's brand new ColdFusion MX.
The main aim of this book is to extend the reader's knowledge of using PHP and MySQL to produce dynamic content for Flash. Essentially, it picks up the baton from the first book and runs with it until there's no more road.
The book takes the reader from being an intermediate to an advanced PHP/Flash developer, and helps them create some awesome Flash-based web applications along the way. It covers the core PHP features, as well as some exciting extras, that follow on directly from the knowledge gained in the first chapter, and show the reader how to use them in real-world applications.
This book covers:Sessions File Uploading Advanced MySQL Socket Functions PHP and XML Ming Plus fully functional case studies
This book is aimed squarely at those readers who want to create dynamic Flash-based web applications, and especially at those who have finished the first book and are hungry for more.
As this book is pitched at those with an intermediate knowledge of PHP (and a decent grasp of MySQL) it has the advantage of being useful to both programmers and those coming over from the first book.
This package combines two vital elements: the most comprehensive and in-depth reference resource for Flash MX ActionScript Rich, and practical tutorials on using ActionScript effectively in your Flash movie design. We've packed in 20 chapters of tutorials, hundreds of detailed reference entries, and hundreds of example FLAs and SWFs. The CD reproduces and expands the complete ActionScript dictionary, providing you with a comprehensive and portable reference tool. To gain an idea of the CD's content, view our online demonstration. You can view all the dictionary's entries, but only the first 30 or so are functional.
Our aim has been to make this book the best Flash MX ActionScript resource, bar none—the book that you'll keep on your desk and never exhaust.

The Internet contains the most useful set of data ever assembled, largely publicly accessible for free. However, this data is not easily reusable. It is embedded within the structure and style of websites and needs to be carefully extracted to be useful. Web scraping is becoming increasingly useful as a means to easily gather and make sense of the plethora of information available online. Using a simple language like Python, you can crawl the information out of complex websites using simple programming.
This book is the ultimate guide to using Python to scrape data from websites. In the early chapters it covers how to extract data from static web pages and how to use caching to manage the load on servers. After the basics we'll get our hands dirty with building a more sophisticated crawler with threads and more advanced topics. Learn step-by-step how to use Ajax URLs, employ the Firebug extension for monitoring, and indirectly scrape data. Discover more scraping nitty-gritties such as using the browser renderer, managing cookies, how to submit forms to extract data from complex websites protected by CAPTCHA, and so on. The book wraps up with how to create high-level scrapers with Scrapy libraries and implement what has been learned to real websites.Style and approach
This book is a hands-on guide with real-life examples and solutions starting simple and then progressively becoming more complex. Each chapter in this book introduces a problem and then provides one or more possible solutions.
