    CString str;
    TCHAR path[MAX_PATH];

    BOOL b = SHGetSpecialFolderPath(NULL, path, CSIDL_PROGRAM_FILES_COMMONX86, 0);//获取指定的系统路径
    /*
    参数1：HWND hwndOwner   窗口所有者的句柄。可以NULL
    参数2：LPTSTR lpszPath  返回路径的缓冲区，该缓冲区的大小至少为MAX_PATH
    参数3：int nFolder      系统路径的CSIDL标识
            CSIDL (constant special item ID list)是系统定义的特殊条目的ID列表
            在vista之后被KNOWNFOLDERID所替代（但为保持兼容性，仍支持CSIDL）
