如何用VC代码实现修改本机的Ip、子网掩码、默认网关、首选DNS服务器啊?

[Hankuu]

Ip、子网掩码、默认网关、首选DNS服务器相关信息在注册表之中，改变注册表的值，然后通知所以应用程序即可，代码如下：
BOOL SetIP(LPCTSTR lpszAdapterName, int nIndex, LPCTSTR pIPAddress, LPCTSTR pNetMask, LPCTSTR pNetGate)
{
HKEY hKey;
CString strKeyName = "SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters\\Interfaces\\";
strKeyName += lpszAdapterName;
if(RegOpenKeyEx(HKEY_LOCAL_MACHINE,
strKeyName,
0,
KEY_WRITE,
&hKey) != ERROR_SUCCESS)
return FALSE;

char mszIPAddress[100];
char mszNetMask[100];
char mszNetGate[100];

strncpy(mszIPAddress, pIPAddress, 98);
strncpy(mszNetMask, pNetMask, 98);
strncpy(mszNetGate, pNetGate, 98);

int nIP, nMask, nGate;

nIP = strlen(mszIPAddress);
nMask = strlen(mszNetMask);
nGate = strlen(mszNetGate);

*(mszIPAddress + nIP + 1) = 0x00;
nIP += 2;

*(mszNetMask + nMask + 1) = 0x00;
nMask += 2;

*(mszNetGate + nGate + 1) = 0x00;
nGate += 2;

RegSetValueEx(hKey, "IPAddress", 0, REG_MULTI_SZ, (unsigned char*)mszIPAddress, nIP);
RegSetValueEx(hKey, "SubnetMask", 0, REG_MULTI_SZ, (unsigned char*)mszNetMask, nMask);
RegSetValueEx(hKey, "DefaultGateway", 0, REG_MULTI_SZ, (unsigned char*)mszNetGate, nGate);

RegCloseKey(hKey);

//通知IP地址改变
BOOL bResult = FALSE;
HINSTANCE hDhcpDll;
DHCPNOTIFYPROC pDhcpNotifyProc;
WCHAR wcAdapterName[256];

MultiByteToWideChar(CP_ACP, 0, lpszAdapterName, -1, wcAdapterName,256);

if((hDhcpDll = LoadLibrary("dhcpcsvc")) == NULL)
return FALSE;

if((pDhcpNotifyProc = (DHCPNOTIFYPROC)GetProcAddress(hDhcpDll, "DhcpNotifyConfigChange")) != NULL)
if((pDhcpNotifyProc)(NULL, wcAdapterName, TRUE, nIndex, inet_addr(pIPAddress), inet_addr(pNetMask), 0) == ERROR_SUCCESS)
bResult = TRUE;

FreeLibrary(hDhcpDll);

return TRUE;
}

这是vbscript写法

'将计算机的 IP 地址设置为 192.168.1.141，并将 IP 网关设置为 192.168.1.100。

strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set colNetAdapters = objWMIService.ExecQuery _
("Select * from Win32_NetworkAdapterConfiguration where IPEnabled=TRUE")
strIPAddress = Array("192.168.1.141")
strSubnetMask = Array("255.255.255.0")
strGateway = Array("192.168.1.100")
strGatewayMetric = Array(1)
For Each objNetAdapter in colNetAdapters
errEnable = objNetAdapter.EnableStatic(strIPAddress, strSubnetMask)
errGateways = objNetAdapter.SetGateways(strGateway, strGatewaymetric)
If errEnable = 0 Then
WScript.Echo "The IP address has been changed."
Else
WScript.Echo "The IP address could not be changed."
End If
Next

Win32_NetworkAdapterConfiguration

The Win32_NetworkAdapterConfiguration WMI class represents the attributes and behaviors of a network adapter. This class includes extra properties and methods that support the management of the TCP/IP and Internetworking Packet Exchange (IPX) protocols that are independent from the network adapter.

The following syntax is simplified from Managed Object Format (MOF) code and includes all inherited properties.

boolean ArpUseEtherSNAP;

最方便的办法就是使用iphelper（需要下载新的Platform SDK），
不过需要WIN2000以上的系统才支持。
