Flex in a Week video training

 This training course will help you understand how you can leverage the opensource Flex framework to build RIAs.  To make it easier to learn Flex, we will use the Eclipse based Flash Builder 4 development tool (formerly Flex Builder) which includes the Flex framework and provides features such as intelligent coding, interactive step-through debugging, and visual design of the user layout.
