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:
一匹马的拼音
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U 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
