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. 、、、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 1 // : Implementation of CHelloApp and DLL registration. 2
