I need a flash aplication written in as3 it is a small computer sell system there will be a database with brand , model , processor, ram , etc, and the user can choose between them and create a custom notebook with his own characteristics so there have to be a connection with a mysql server Optionaly: I need that the app load his code externaly ..just for give me the control to disable it across the internet.. It could be an external .as file loaded from a different server, with some kind of password. Or any better idea from your brillants minds.
