以下函数可分别 获取主机硬件信息：
CPU, cpuid
硬盘，hardDisk
主板，motherBoared
网卡信息,netInterfaceCard.
通过WMI接口获取硬件信息，但这些信息有些未必可靠

思路：
保存activeCode到
HKEY_CURRENT_USER\\Software\\qCloudSecChk\\activeCode中
程序每次打开时，先读取 注册表
HKEY_CURRENT_USER\\Software\\qCloudSecChk\\activeCode
，如果为空，则提示需要激活，如果存在，进行下一步：
获取机器信息getMachineInfo(),计算calMachineCode，计算激活码calActiveCode与activeCode进行对比，一致说明已激活，否则提示激活。
有效期限制：首次激活时，validRecord到
HKEY_CURRENT_USER\\Software\\qCloudSecChk\\validRecordTime
程序每次打开，确认已激活后，打开上述位置，读取第一次激活时间，与当前时间对比，根据激活码匹配情况（120，180，360，730），选择对应时间阈，提示软件是否过期，是否需要重新注册。另外，不能仅依赖于注册表，应该建立一些特殊位置的隐藏文件辅助上述的激活、有限期设置工作。
