学flash好还是flex好?请大家给我出一点意见
我是做.NET开发的,已经弄.NET好久了,并且主要是做网站方面的开发,好多的时候需要用到FLASH的东西,一般就是到网络上去搜索一下就能找到想要的了,便是有的时候还是找不到合适的,很久以前就想学FLASH了,但是学了一半,NND,听说HTML5要出来了,FLASH不有什么优势,要死了,就放弃了,想想当时的想法真是....,就像IE6早过时了,但是现在的市场占有率却是最高的,我想就算FLASH哪天死了的话,那时候我可能都不弄了,呵呵,所以想学一下相应的东西,但是现在有一个FLASH和一个FLEX,不知道学哪个要好,请各位给我一个基于我情况的建议,在此谢谢大家咯!!!

How is Flex different from Flash?

Both Flash and Flex applications are rendered in the browser using the Adobe Flash Platform runtimes, including Flash Player, and outside the browser using the Adobe AIR runtime.

Flash Professional is the leading authoring tool for web developers, multimedia professionals, animators, and videographers who want to create interactive content.

Developers may find it difficult to use Flash Professional to create applications. Flex provides developers who know traditional programming technologies like Java, PHP, ColdFusion, Ajax, and .NET with an easy-to-learn application framework to create RIAs. In addition, developers can embed rich elements inside a Flex application. Using the Flex Component Kit for Flash, developers can create custom Flex components from Flash Professional.
