WMI资料：[http://blog.csdn.net/column/details/15832.html][http_blog.csdn.net_column_details_15832.html]

vc使用wmi例子：[http://blog.csdn.net/jiftlixu/article/details/7473727][http_blog.csdn.net_jiftlixu_article_details_7473727]

IP修改方法，请看我上上篇博客，这里不再介绍了。我遇到一个头疼的问题就是win7不支持

DhcpNotifyConfigChange这个函数，无法热启动

网上给的方法：

1、网卡重启；

2、netsh指令；

3、WMI指令；

我有幸，从网上找到了WMI的例子，现分享如下：

说明：

1、原来的帖子只有开启WMI服务，并没有关闭WMI服务，因此第二次打开会报错：1008，An attempt was made to reference a token that does not exist

因此我加上了关闭服务函数。

2、原来的网上的帖子DhcpNotifyConfigChange历程，在释放空间的时候都是错的，不明白为什么大家都不指正，我在这里也一并修改了，

具体代码如下：

头文件：

\#include <WinSock2.h>  
\#include <Iphlpapi.h>  
\#include <iostream>  
  
  
\#include <WinError.h>  
  
  
\#include <comdef.h>  
\#include <Wbemidl.h>  
\#include "atlbase.h"  
  
  
\#pragma comment(lib, "wbemuuid.lib")  
  
  
//using namespace std;  
\#pragma comment(lib,"Iphlpapi.lib") //需要添加Iphlpapi.lib库  
\#pragma comment(lib,"dhcpcsvc.lib") //需要添加dhcpcsvc.lib库

一、查找本地网卡

bool CMySocket::SelectNetWorkCard(CComboBox* pAddCComboBox)
    {
        if(NULL == pAddCComboBox){
            return false;
        }
       pAddCComboBox->ResetContent();
    
    
        //AllocConsole();
        //freopen("CONOUT$","w",stdout);
        //PIP_ADAPTER_INFO结构体指针存储本机网卡信息
        PIP_ADAPTER_INFO pIpAdapterInfo = new IP_ADAPTER_INFO();
        //得到结构体大小,用于GetAdaptersInfo参数
        unsigned long stSize = sizeof(IP_ADAPTER_INFO);
        //调用GetAdaptersInfo函数,填充pIpAdapterInfo指针变量;其中stSize参数既是一个输入量也是一个输出量
        int nRel = GetAdaptersInfo(pIpAdapterInfo,&stSize);
        //记录网卡数量
        int netCardNum = 0;
        //记录每张网卡上的IP地址数量
        int IPnumPerNetCard = 0;
        if (ERROR_BUFFER_OVERFLOW == nRel){
            //如果函数返回的是ERROR_BUFFER_OVERFLOW
            //则说明GetAdaptersInfo参数传递的内存空间不够,同时其传出stSize,表示需要的空间大小
            //这也是说明为什么stSize既是一个输入量也是一个输出量
            //释放原来的内存空间
            delete pIpAdapterInfo;
            //重新申请内存空间用来存储所有网卡信息
            pIpAdapterInfo = (PIP_ADAPTER_INFO)new BYTE[stSize];
            //再次调用GetAdaptersInfo函数,填充pIpAdapterInfo指针变量
            nRel=GetAdaptersInfo(pIpAdapterInfo,&stSize);    
        }
        PIP_ADAPTER_INFO pIpAdapterInfoTemp = pIpAdapterInfo;
        if (ERROR_SUCCESS == nRel){
            //输出网卡信息
            //可能有多网卡,因此通过循环去判断
            while (pIpAdapterInfoTemp){
                //cout<<"网卡数量："<<++netCardNum<<endl;
                //cout<<"网卡名称："<<pIpAdapterInfo->AdapterName<<endl;
                //cout<<"网卡描述："<<pIpAdapterInfo->Description<<endl;
                pAddCComboBox->AddString(pIpAdapterInfoTemp->Description);
                switch(pIpAdapterInfoTemp->Type){
                case MIB_IF_TYPE_OTHER:
                    //cout<<"网卡类型："<<"OTHER"<<endl;
                    break;
                case MIB_IF_TYPE_ETHERNET:
                    //cout<<"网卡类型："<<"ETHERNET"<<endl;
                    break;
                case MIB_IF_TYPE_TOKENRING:
                    //cout<<"网卡类型："<<"TOKENRING"<<endl;
                    break;
                case MIB_IF_TYPE_FDDI:
                    //cout<<"网卡类型："<<"FDDI"<<endl;
                    break;
                case MIB_IF_TYPE_PPP:
                    //printf("PP\n");
                    //cout<<"网卡类型："<<"PPP"<<endl;
                    break;
                case MIB_IF_TYPE_LOOPBACK:
                    //cout<<"网卡类型："<<"LOOPBACK"<<endl;
                    break;
                case MIB_IF_TYPE_SLIP:
                    //cout<<"网卡类型："<<"SLIP"<<endl;
                    break;
                default:
    
                    break;
                }
                //cout<<"网卡MAC地址：";
                for (DWORD i = 0; i < pIpAdapterInfoTemp->AddressLength; i++){
                    if (i < pIpAdapterInfoTemp->AddressLength-1){
                        //printf("%02X-", pIpAdapterInfo->Address[i]);
                    }
                    else{
                        //printf("%02X\n", pIpAdapterInfo->Address[i]);
                    }
                }
                //cout<<"网卡IP地址如下："<<endl;
                //可能网卡有多IP,因此通过循环去判断
                IP_ADDR_STRING *pIpAddrString =&(pIpAdapterInfoTemp->IpAddressList);
                IPnumPerNetCard = 0;
                do {
                    //cout<<"该网卡上的IP数量："<<++IPnumPerNetCard<<endl;
                    //cout<<"IP 地址："<<pIpAddrString->IpAddress.String<<endl;
                    //cout<<"子网地址："<<pIpAddrString->IpMask.String<<endl;
                    //cout<<"网关地址："<<pIpAdapterInfo->GatewayList.IpAddress.String<<endl;
                    pIpAddrString=pIpAddrString->Next;
                } while (pIpAddrString);
                pIpAdapterInfoTemp = pIpAdapterInfoTemp->Next;
                //cout<<"--------------------------------------------------------------------"<<endl;
            }
    
        }
        //释放内存空间
        if (pIpAdapterInfo)
        {
            delete pIpAdapterInfo;
        }
    
        //FreeConsole();
        return true;
    }

二、修改注册表IP

bool CMySocket::RegSetIP(LPCTSTR lpszAdapterName, 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);

int  wIsEnableDHCP=0;
    
        *(mszIPAddress + nIP + 1) = 0x00;   // REG_MULTI_SZ数据需要在后面再加个0
        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);
        RegSetValueEx(hKey, "EnableDHCP", 0, REG_DWORD, (unsigned char*)&wIsEnableDHCP, sizeof(DWORD) );
    
        RegCloseKey(hKey);
    
    
        return true;
    }

三、NotifyIPChange修改网卡IP

bool CMySocket::NotifyIPChange(LPCTSTR lpszAdapterName, int nIndex, LPCTSTR pIPAddress, LPCTSTR pNetMask)
    {
        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){
            int i=0;
            i = (pDhcpNotifyProc)(NULL, wcAdapterName, TRUE, nIndex, inet_addr(pIPAddress), inet_addr(pNetMask), 0);
            if(ERROR_SUCCESS == i){
                bResult = TRUE;
            }else{
                bResult = ANWMIInit(wcAdapterName);
            }
            //if((pDhcpNotifyProc)(NULL, wcAdapterName, TRUE, nIndex, inet_addr(pIPAddress), inet_addr(pNetMask), 0) == ERROR_SUCCESS){
            //    bResult = TRUE;
            //}
        }
    
    
        FreeLibrary(hDhcpDll);
        return bResult;
    }

四、WMI修改网卡IP

bool CMySocket::ANWMIInit(PCWSTR pszAdapterName)
    {
    
        IWbemLocator* g_pLoc = NULL;
        IWbemServices* g_pSvc = NULL;
        IEnumWbemClassObject* g_pEnum = NULL;
        IWbemClassObject* g_pAdapterObject = NULL;
        //IWbemClassObject* g_pAdapterConfigClass = NULL;
        //VARIANT g_AdapterConfigPathVal;
    
        HRESULT hres;
        CComBSTR TheQuery = NULL;
        ULONG NumObjects = 0;
    
    
        // Step 1: Initialize COM.
        hres =  CoInitializeEx(0, COINIT_MULTITHREADED); 
        if (FAILED(hres)){
            OutputDebugString("CoInitializeEx failed!!\n");
            return false;                  
        }
    
    
        // Step 2: Set general COM security levels
        // Note: If you are using Windows 2000, you need to specify -
        // the default authentication credentials for a user by using
        // a SOLE_AUTHENTICATION_LIST structure in the pAuthList ----
        // parameter of CoInitializeSecurity ------------------------
    
        hres =  CoInitializeSecurity(
            NULL, 
            -1,                          // COM negotiates service
            NULL,                        // Authentication services
            NULL,                        // Reserved
            RPC_C_AUTHN_LEVEL_DEFAULT,   // Default authentication 
            RPC_C_IMP_LEVEL_IMPERSONATE, // Default Impersonation  
            NULL,                        // Authentication info
            EOAC_NONE,                   // Additional capabilities 
            NULL                         // Reserved
            );
    
        CString strTemp;
        strTemp.Format("%d",::GetLastError());
        //FormatMessage();
        if (FAILED(hres)){
            OutputDebugString(strTemp+"\n");
            OutputDebugString("CoInitializeSecurity failed!!\n");
            return false;                     
        }
    
        // Step 3:  Obtain the initial locator to WMI
        hres = CoCreateInstance(
            CLSID_WbemLocator,             
            0, 
            CLSCTX_INPROC_SERVER, 
            IID_IWbemLocator, 
            (LPVOID*)&g_pLoc);
    
        if (FAILED(hres)){
            OutputDebugString("CoCreateInstance failed!!\n");
            return false;                
        }
    
    
        // Step 4: Connect to the local root\cimv2 namespace and obtain pointer pSvc to make IWbemServices calls.
        hres = g_pLoc->ConnectServer(
            _bstr_t(L"ROOT\\CIMV2"), 
            NULL,
            NULL, 
            0, 
            NULL, 
            0, 
            0, 
            &g_pSvc
            );
