/*
 * VS2005在添加Shockwave时很多人都碰到一个这个问题,就是会说ActiveX注册失败
 * 先要用Regsvr32来注册ActiveX(运行:Regsvr32 控件名)-u为卸载参数
 * Regsvr32 C:\WINDOWS\system32\Macromed\Flash\Flash32_18_0_0_203.ocx -u
 * Regsvr32 C:\WINDOWS\system32\Macromed\Flash\Flash32_18_0_0_203.ocx
 * 在VS2005下项目-属性-生成-目标平台改为x86
　　在选择生成-清理解决方案与重新生成解决方案直到资源管理器的引用下的AxShochwaveFlashObj的黄色感叹号消失
