RegSvr32 加载失败，找不到指定的模块

应用ocx注册时, 出现下图错误:

解决方案（检测缺少库）:

　　0. 使用管理员运行cmd，注册ocx

　　1. mfc100.dll、mfc100u.dll、msvcp100.dll、msvcr100.dll之类的库（可能是ocx工程属性为Use MFC in a Shared DLL）

　　2. 可能是缺少应用程序需要的库，可以写个简单的win32控制台程序。

　　　(ocx依赖的库全部#pragma comment进来，调用一个库函数)，运行demo，会提示缺少库的名称

       2. 或者使用win32程序直接调用ocx，查看错误提示

　   3. 使用depends工具查看缺少库

　　4. 工程间使用不同的MD(MDD)、MT(MTD),  也可能导致程序无法运行

附ocx注册为安全组件代码
