您当前的位置: 现在有如下命令需要通过VFP调用：
netsh interface ip set address "本地连接" source= static addr=192.168.48.78 mask=255.255.255.0 gateway=192.168.48.56 gwmetric=1
netsh interface ip set dns "本地连接" static 192.168.48.85 primary
2句命令，是通过命令设置IP地址和DNS
由于IP地址是不固定的，我首先考虑通过run的方式实现，但run(".....")失败，原来上面命令中【本地连接】二侧必须用双引号，不能使用单引号。
那我有想到做个脚本，然后VFP调用，但问题是我用run("c:ip.bat")也失败，请问题原因。
由于我的IP地址不固定，我后台有个地址表，最好可以从表中读取，请问有办法吗？

方法一
通过代码修改IP地址或网关、子网掩码、首选DNS、备用DNS
*--------------------
- SQL code
****调用方式****
*SetLocalIP( tcCard,tcAddr, tcMask, tcGateWay,tcDNS,tcAddDNS )
*例如：
SetLocalIP( '本地连接','192.168.0.180','255.255.255.0','192.168.0.1','192.168.0.1','192.168.0.3' )
