散尽分数，请问如何将网卡设置为“指定IP”地址状态？

Question

rt，只是大概知道好像可以用WMI来实现，但是具体怎么做呢？望大侠指教！！

for more WMI usage, refer to http://www.fruitfruit.com/vc/hardware/usewmi.cpp
BSTR InstancePath = SysAllocString(L"Win32_NetworkAdapterConfiguration=2");  in my computer, network card index is 2, your computer may have a different index

直接用API可以实现啊！！！！！！！！！！！
