Module Name: ipchange.cppAbstract: This module illustrates how to programmatically change an IP address for
a specific network adapter on your machine. This program also demonstrates how
to retrieve existing network adapter IP configuration information. IP configurations can be changed for a specific network adapter by using the
AddIpAddress() and DeleteIpAddress() Ip Helper APIs. These APIs require you to
understand adapter index numbers and IP context numbers. In Windows, every network
adapter has a unique index ID and every IP address has a unique context ID.
Adapter index IDs and IP context numbers can be retrieved using the GetAdaptersInfo()
IP Helper API. This program features a list option that displays current network
adapter configuration information by showing all adapters index numbers and IP
address context numbers associated with their corresponding network adaptors. To execute this application, simply build the application using the Visual C++
Nmake.exe program generation facility. A ipchange.exe program should result.
Execute the ipchange.exe with the following parameters: Ipchange.exe [ -l ] [ -a -n<index id> -i<ip address> -m<subnet mask> ]
[ -d -c<context id>] -l List adapter index IDs and IP Address context ID information
-a Add IP Address option
-d Delete IP Address option
-i IP Address to specify with -a option
-m Subnet Mask to specify with -a option
-c IP context ID for an existing IP address
-n Index ID of an existing network adapterAuthor: Jim Ohlund 21-Apr-98Revision History:*/#include <windows.h>

+ 你的网卡名字下面的 IPAddress 就OK了如果不想重新启动就生效,则还需要使用dhcpcsvc.dll中提供的未公开函数DhcpNotifyConfigChange
来通知系统IP地址的改变:)需要源代码的话直接给我发消息
