Flex4_与Flash通信

方法一：

    使用LocalConnection对象，据说不受AS版本限制。

    1、Flash端，在需要通信的位置插入代码：
   

       var localConn:LocalConnection=new LocalConnection();
       //lc_from_flash：是建立连接的字符串，该字符串必须与Flex中connect（）方法中所需参数一致。
        //ShowDetails：为Flex提供的Public方法。
        //5：ShowDetails方法的数值参数
        localConn .send("lc_from_flash","ShowDetails",5); 

  2、Flex端
