Flex Guru

In Flex 3 New Features, instructor David Gassner takes viewers through each new feature of the application. He goes over installing Flex 3 on Windows and Mac OSX, explores changes in the interface, teaches how to integrate Flex applications with javascript, demonstrates the new Design View and Source View capabilities, and much more.

Application developers who want to create cross-platform, data-centric applications need the power of Flex 3. In Flex 3 Essential Training, Adobe Certified Instructor David Gassner starts with the basics of understanding Flex, its projects, and its related programming languages. He explores the intricacies of the development platform and the Flex Builder 3 integrated development environment, then gives in-depth, hands-on tutorials on creating, designing, customizing, and publishing dynamic web and desktop applications in Flex 3. Exercise files accompany the course. 

This book walks the reader through all of the steps that a beginning user must tackle, including
which software to install, how to install it, and how to start writing code. It's assumed that the
reader has some knowledge of how the web works and has worked with plain old HTML. The
differences between using Flex, HTML, and Ajax are dissected in easy-to-understand terms.
All the major starting points of developing RIAs in Flex are covered, including a
detailed description of the ActionScript programming language that forms the basis for
Flex applications. The Flex framework, which speeds application development time, is
discussed after you've learned about the Flex architecture and supporting languages. Each
step of the way is written to make sometimes complex concepts easy to understand.
Because Flex excels at working with media assets such as video and sound combined
with dynamic data to create a rich Web 2.0 experience, the book introduces the necessary
concepts to create these applications. Those concepts include working with sounds and
video as well as working with dynamic data sources such as an RSS feed. With a solid
starting point, the options for creating Flex applications are endless.
Finally, practical advice is provided to help debug and publish applications once youre
cranking out applications that youre ready to share with your friends and colleagues.

The source code for examples in the book is downloadable on the web from www.
mhprofessional.com. Any example of more than a few lines should be downloaded from
the source code to reduce the time required to type in the code and to avoid any errors from
typing in the code.
The source code and related media assets are split out by chapter number. For code
segments that have a heading with a listing number, the code is placed in a file called
Listing_



. ActionScript files are named the same as
the examples class name, since Flex requires the filename to match the class definition.
MXML code listings that are not large enough to warrant their being referred as a listing
in the text are named Example_, where description
provides guidance on which example is being reference in the text. Any media assets are
also named the same as their references in the text.
In general, MXML examples can be run in the same project as other examples from
the text. The ActionScript files that demonstrate importing sounds and SWF media assets
should be created as ActionScript projects for each example. Flex Builder automatically
places some default code when creating a new MXML or ActionScript file, but it's okay
to overwrite this default code with the source from the files provided with the book.

With the ease of development & multi-platform support, Adobe AIR is a getting-popular choice for creating desktop applications. There are many beautiful applications built with it including the ones that are functional for the designer & developer community.
Months ago, a post published at WRD was sharing 27 Adobe AIR Applications - Handy For Web Designers. Since then, there are various great applications created.
And here they are, 16 Fresh Adobe AIR Applications For Designers & Developers:

ImageSizer

ImageSizer is a batch image processor tool which can resize, optimize and rename multiple JPG files.
Once the images are processes, they can be exported as a single .zip file.
