[Flex]Flash Player debug版本问题解决

孤影 — Thu, 30 Oct 2008 02:51:00 GMT

删除注册表中之前安装的版本记录就可以了

注册表:HKEY_LOCAL_MACHINE\SOFTWARE\Macromedia\FlashPlayer\SafeVersions

删除最高版本的键值.

关于WEB应用程序的开发前台与后台

孤影 — Sun, 26 Oct 2008 13:04:00 GMT

本身是做Java Web Appliction的，谁知道换了个城市随之而来的也换了工种，做起来前台了，Flex...新东西，看了3天官方Reference头大，又要记新的API了。算了，自我安慰下，对于Flex的前景还算不错的，未来随着网速的拓宽，Flex终究会称为主流的，就当是新时代来临前的磨练吧，努力下让自己多熟悉点东西有什么不好。加油吧~
