Description: Chapter 2: Getting Started Hello World
Hello World Enhanced A simple "Hello World" application that shows the basics of how to use an ActionScript 3.0 class in an application. The Enhanced version adds a name-checking feature. These examples are meant to be built from scratch, tutorial-style. The example files are provided so you can see how they should look when completed.
Chapter 4: Object-Oriented Programming Geometric Shapes Uses the object-oriented concepts of class inheritance and the implementation of interfaces to provide an application that calculates values for simple geometric shapes.
Chapter 5: Display Programming Sprite Arranger Adds graphical Sprite objects to a drawing area and let you manipulate their placement in the display list. Builds upon the classes from the geometric Shapes example.
Chapter 6: Working with Dates and Times Simple Clock Displays a simple analog clock face using methods of the Date and flash.util.Timer classes.
Chapter 7: Working with Strings ASCII Art Loads bitmap images and coverts them into ASCII character equivalents, using a number of the methods in the String class.
Chapter 8: Working with Arrays Play List Demonstrates a number of methods of the Array class while building and presenting a play list of music files.
Chapter 9: Handling Errors Custom Errors Presents a simple framework containing a set of custom ApplicationError classes and shows how to throw, catch, and handle such errors.
Chapter 10: Using Regular Expressions Wiki Editor Uses regular expressions to convert text containing wiki-style codes into formatted HTML text. Also shows how to use regular expressions for other conversions, such as numeric calculations.
Chapter 11: Working With XML RSS Viewer Reads an RSS feed and formats the entries as HTML, including hyperlinks to the stories being referenced. This example shows the powerful new E4X statements and operators in action.
Chapter 13: Event Handling Alarm Clock Demonstrates how to define, dispatch, and handle custom event classes. Extends the Simple Clock application to create an Alarm Clock with specialized AlarmEvents.
Chapter 14: Networking and Communications File I/O Shows how to use the FileReference class to upload files from your local disk to a remote server, and how to download files from a remote server to your local disk.
Note: To run this example you will need to set the UPLOAD_URL and DOWNLOAD_URL variables in the code to the address of a web server that will accept uploads and allow downloads.
Telnet Socket Connects to a Telnet server and shows how to send and read bytes from the socket connection.
Note: To run this example you will need to have access to a running Telnet server.
Chapter 15: Working with Geometry Display Object Transformer Uses methods of the flash.geom.Matrix class to apply multiple geometric transformations to a DisplayObject.
Chapter 16: Client System Environment Capabilities Info Lists the capabilities of your current browser and operating system, by using the SystemCapabilities class and an ExternalInterface call that uses Javascript to retrieve browser properties.
Chapter 19: Using the External API IntrovertIM_CSharp
IntrovertIM_HTML A tiny instant messenger application the uses the flash.external.ExternalInterface class to send messages between a Flex/ActionScript application and an external application. Two versions are provided. One uses HTML and Javascript for the external application, and the other uses C#.
