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?

Answer 1

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;
}

Answer 2

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_NetworkAdapterConfigurationThe 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.

用iphelper可以解决很多问题，下面是使用的例子

Answer 5

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。
