Hello. I would like to start playing around with creating Flash apps. Particularly, I would like to make a little app that lets me draw a shape outline, on my website, and figure out how many squares I can fit into that space. I would like to record the results. I have been playing around with developing some apps in Windows Forms and WPF for a while. I have a somewhat good handle on the C# programming language. I do not know where to start with developing Flash apps though. Do I purchase Flex Builder and do Action Scrip tutorials, do I purchase regular Flash, or do I use my old version of Flash (2004MX from wayyyyyy back)? Not sure where to start… Any advice?
