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?
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?
------解决方案--------------------
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;
