Window 注册程序关联后缀文件，双击运行
一般来说，很多软件都会有自定义后缀的文件，比如.cpp、.doc等，那么如果我们想把这些后缀与我们的软件关联起来，如何做呢

调用：
一般是在初始化HINSTANCE 的地方：
如bool CWndShadow::Initialize(HINSTANCE hInstance)
我这里使用的是CWndShadow类，这是一个开源的阴影类，可以google一下
//注册程序与文件后缀名的关联 CRegExtension reg; reg.RegisterFileAndProgram(); // 分析标准外壳命令、DDE、打开文件操作的命令行 if (__argc > 1) { m_csFilePath = __targv[1];//我使用这种方式获取双击的后缀文件的所在路径 }
这样就可以双击运行软件了
