Rich Flash Internet Web Applications

With the advent of Flash 5 and MX the ability to create truly robust web applications finally became a reality. The stateless nature of the Web didn’t lend itself to creating rich user experiences like those found in desktop applications, but Flash came along and provided the mechanism to display text, graphics, and video and to maintain information on the client, dynamically requesting information from a database behind the scenes via a server-side programming language such as ASP.NET, JSP, PHP, or ColdFusion. The player got faster in many ways as it matured, while keeping the critical download size as small as possible. Macromedia started to make drastic improvements to the player to increase its speed and to open opportunities for developers to create inspirational sites (see Figure 1-3 for an example). The XML object was converted to a native data type in Flash Player 6, which meant the new player blazed through data received from a web service, file store, or server-side script.

New possibilities, such as real-time, multiuser chats, began to be exploited across the globe. The XMLSocket class allowed two-way communication with socket servers written in Java, Perl, or even PHP, and third parties began to make tools to interface with a Flash client, providing detailed APIs to aid
development. Macromedia also introduced smart clips in Flash 5, which matured into fully functional user interface components in Flash MX. These components included buttons, validated text input fields, pie charts, and data grids. Best of all, you could view the source for a component and extend the functionality to meet any need without having to write your own component from scratch.

The version 2 component architecture, introduced in Flash MX 2004, provides a flexible yet powerful base for creating and extending components. This base allows developer communities to discuss common issues and solutions because of the shared, standardized nature of the architecture. Third parties have also created both open source and commercial component frameworks that are compatible with the Macromedia component architecture yet provide extra functionality, speed, and corrections for some of the things found lacking in the original architecture. The Flash Player has become the vessel for all great web experiences, finding its place first in the experimental and then in the commercial. Flash application development is rapid, cross-platform, and, best of all, tried and tested.

Peripheral Flash technologies

Flash also incorporates a whole collection of peripheral technologies designed to add more power to
Your applications . These technologies usually run on a server, although Flash-based technologies have
started to appear on desktops and embedded devices as well. I’d like to go over several of the most
common peripherals and examine what they offer for Flash development.
