There should be a ton of articles online discussing this and I see Abdul gave a good summary before. Here's my quick summary here... both Flex and Flash applications are ultimately compiled down to a SWF file and run in the Flash Player. They both use ActionScript to write programmatic logic and they can make use of graphic, video and audio assets. However, the way in which the applications are built is very different. Flash applications are typically built with the Flash Authoring tool and focus around stages, timelines, labels and script blocks to control program flow. Flex applications are typically built with Flex Builder; the concept of a "timeline" is effectively absent. Developing Flex applications should feel like a hybrid between web development and traditional GUI application development, but with a rich set of pre-built components. The Flex developer uses an XML language to declaritively layout the UI and writes formal classes to extend existing components or write completely new logic. From Flex 2 we target Flash Player 9 and ActionScript 3.0. Pete
