First, yes, screen readers can read Flex applications. And yes, its fairly
easy. But, I’ll discuss how in a future post.
But, if you’d rather send people to your old HTML version of your site when
using a read, there is good news. Flash Player has the ability to detect if a
screen reader is running on the client machine, even if JavaScript is
disabled and/or the Flex application is not compiled as an “accessible
swf”. This is possible with the Accessibility class.
It is important to note that if the Flex application is compiled as an
“accessible swf”, the screen reader will also be able to read content in
the swf. If not, the screen reader only reads the words “flash movie
start” whenever you interact with it. Talk about a usability buzz kill.
So, here is the code to see if a screen reader is currently running (not just
installed) and then adds a LinkButton that call... (more)

The core of Flash Player is the Tamarin Virtual Machine, which is an open

influenced by the community and their needs. The core language for Flash
Player is an implementation of ECMAScript 262, which is the same
specification for JavaScript. Flex also uses CSS for s... (more)

buttons in our Web browser to review or backtrack previously viewed content.
We are trained to the point that there are even keyboard shortcuts.
Unfortunately, this can be a problem when browsing Flex applications. Being
the well-trained users that we are, we often forget that we could cause the
Flex application to reload unwittingly.
Fortunately, there is a solution that is built into the Flex SDK and HTML
templates that are generated in a Flex Builder project. By default, Flex
enables history managemen... (more)
