收集整理的這篇文章主要介紹了
wince下实现wifi无线网络的连接和配置（WLAN）
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
在 Windows CE 下自帶有無線網卡的配置和連接程序，但是如果系統剪裁掉了資源管理器和任務欄，或者再CE的很多應用中，是不允許用戶回到桌面去調用系統的連接程序的，這篇文章就來談一下如何用那么可以利用微軟自帶的WZC函數來重新編寫一個獨立于系統的WIFI連接程序。

存放SSID的基本信息的數據結構: [cpp] view plaincopyprint?/*SSID基本信息*/ typedef struct tag_SsidInfo { wstring sSsid; int nRssi; NDIS_802_11_NETWORK_INFRASTRUCTURE InfrastructureMode; ULONG ulPrivacy; NDIS_802_11_AUTHENTICATION_MODE AuthenticationMode; int iKeyIndex; wstring pKey; int iEapType; }SsidInfo;
/*SSID基本信息*/
typedef struct tag_SsidInfo
{ wstring sSsid; int nRssi; NDIS_802_11_NETWORK_INFRASTRUCTURE InfrastructureMode; ULONG ulPrivacy; NDIS_802_11_AUTHENTICATION_MODE AuthenticationMode; int iKeyIndex; wstring pKey; int iEapType;
}SsidInfo;
BOOL GetFirstWirelessCard(PTCHAR pCard) { WifiCallBack=NULL; if (!pCard) { return FALSE; } INTFS_KEY_TABLE IntfsTable; IntfsTable.dwNumIntfs = 0; IntfsTable.pIntfs = NULL; _tcscpy(pCard, TEXT("")); // 枚舉系統中可用的無線網卡 DWORD dwStatus = WZCEnumInterfaces(NULL, &IntfsTable); if (dwStatus != ERROR_SUCCESS) { RETAILMSG(1, (TEXT("WZCEnumInterfaces() error 0x%08X\n"),dwStatus)); return FALSE; } // 判斷無線網卡的數量，可以根據無線網卡數量來枚舉出所有可用的無線網卡 if (!IntfsTable.dwNumIntfs) { RETAILMSG(1, (TEXT("System has no wireless card.\n"))); return FALSE; } _tcscpy(pCard, IntfsTable.pIntfs[0].wszGuid); LocalFree(IntfsTable.pIntfs); return TRUE; }
BOOL GetFirstWirelessCard(PTCHAR pCard)
{ WifiCallBack=NULL;if (!pCard) { return FALSE; } INTFS_KEY_TABLE IntfsTable; IntfsTable.dwNumIntfs = 0; IntfsTable.pIntfs = NULL; _tcscpy(pCard, TEXT("")); // 枚舉系統中可用的無線網卡 DWORD dwStatus = WZCEnumInterfaces(NULL, &IntfsTable); if (dwStatus != ERROR_SUCCESS) { RETAILMSG(1, (TEXT("WZCEnumInterfaces() error 0x%08X\n"),dwStatus)); return FALSE; } // 判斷無線網卡的數量，可以根據無線網卡數量來枚舉出所有可用的無線網卡 if (!IntfsTable.dwNumIntfs) { RETAILMSG(1, (TEXT("System has no wireless card.\n"))); return FALSE; } _tcscpy(pCard, IntfsTable.pIntfs[0].wszGuid); LocalFree(IntfsTable.pIntfs); return TRUE;
}
2.從無線網卡取得無線網絡信息 [cpp] view plaincopyprint?// // pCard: 無線網卡 GUID // pIntf: 無線網卡配置信息結果體 // pOutFlags: 網卡配置信息掩碼標志 // BOOL GetWirelessCardInfo(PTCHAR pCard, PINTF_ENTRY_EX pIntf, PDWORD pOutFlags) { TCHAR *szWiFiCard = NULL; // 參數校驗 if (!pCard || !pIntf || !pOutFlags) { //RETAILMSG(1, (TEXT("Param Error.\n"))); return FALSE; } szWiFiCard = pCard; *pOutFlags = 0; // 初始化無線網卡信息 ZeroMemory(pIntf, sizeof(INTF_ENTRY_EX)); // 設置 GUID 號 pIntf->wszGuid = szWiFiCard; // 查詢無線網卡信息 DWORD dwStatus = WZCQueryInterfaceEx(NULL, INTF_ALL, pIntf, pOutFlags); if (dwStatus != ERROR_SUCCESS) { //RETAILMSG(1, (TEXT("WZCQueryInterfaceEx() error 0x%08X\n"), dwStatus)); return FALSE; } return TRUE; }
//
// pCard: 無線網卡 GUID
// pIntf: 無線網卡配置信息結果體
// pOutFlags: 網卡配置信息掩碼標志
//
BOOL GetWirelessCardInfo(PTCHAR pCard, PINTF_ENTRY_EX pIntf, PDWORD pOutFlags)
{ TCHAR *szWiFiCard = NULL; // 參數校驗 if (!pCard || !pIntf || !pOutFlags) { //RETAILMSG(1, (TEXT("Param Error.\n"))); return FALSE; }szWiFiCard = pCard; *pOutFlags = 0; // 初始化無線網卡信息 ZeroMemory(pIntf, sizeof(INTF_ENTRY_EX)); // 設置 GUID 號 pIntf->wszGuid = szWiFiCard; // 查詢無線網卡信息 DWORD dwStatus = WZCQueryInterfaceEx(NULL, INTF_ALL, pIntf, pOutFlags); if (dwStatus != ERROR_SUCCESS) { //RETAILMSG(1, (TEXT("WZCQueryInterfaceEx() error 0x%08X\n"), dwStatus)); return FALSE; } return TRUE;
}
3.解析這些信息，得到需要的無線網參數，ssid，信號強度，加密方式等等void GetWirelseeListSSID(const PRAW_DATA prdBSSIDList,vector<SsidInfo> &SsidList) { SsidInfo tempInfo; WCHAR tSsid[MAX_PATH]; if (prdBSSIDList == NULL || prdBSSIDList->dwDataLen == 0) { // RETAILMSG(DBG_MSG, (TEXT("<null> entry.\n"))); return; } else { PWZC_802_11_CONFIG_LIST pConfigList = (PWZC_802_11_CONFIG_LIST)prdBSSIDList->pData; //RETAILMSG(DBG_MSG, (TEXT("[%d] entries.\n"), pConfigList->NumberOfItems)); int i; // 枚舉所有無線AP for (i = 0; i < pConfigList->NumberOfItems; i++) { PWZC_WLAN_CONFIG pConfig = &(pConfigList->Config[i]); RAW_DATA rdBuffer; rdBuffer.dwDataLen = pConfig->Ssid.SsidLength; rdBuffer.pData = pConfig->Ssid.Ssid; // 將 SSID 的 ASCII 碼轉化成字符串 memset(tSsid,0,sizeof(tSsid)); PrintSSID(&rdBuffer, tSsid); tempInfo.sSsid=wstring(tSsid); tempInfo.nRssi=(int)pConfig->Rssi; tempInfo.InfrastructureMode=pConfig->InfrastructureMode; tempInfo.AuthenticationMode=pConfig->AuthenticationMode; tempInfo.ulPrivacy=pConfig->Privacy; if (WifiCallBack) { WifiCallBack(tempInfo); } SsidList.push_back(tempInfo); } } }
void GetWirelseeListSSID(const PRAW_DATA prdBSSIDList,vector<SsidInfo> &SsidList)
{SsidInfo tempInfo;WCHAR tSsid[MAX_PATH];if (prdBSSIDList == NULL || prdBSSIDList->dwDataLen == 0){// RETAILMSG(DBG_MSG, (TEXT("<null> entry.\n")));return;}else{PWZC_802_11_CONFIG_LIST pConfigList = (PWZC_802_11_CONFIG_LIST)prdBSSIDList->pData;//RETAILMSG(DBG_MSG, (TEXT("[%d] entries.\n"), pConfigList->NumberOfItems));int i;// 枚舉所有無線APfor (i = 0; i < pConfigList->NumberOfItems; i++){PWZC_WLAN_CONFIG pConfig = &(pConfigList->Config[i]);RAW_DATA rdBuffer;rdBuffer.dwDataLen = pConfig->Ssid.SsidLength;rdBuffer.pData = pConfig->Ssid.Ssid;// 將 SSID 的 ASCII 碼轉化成字符串memset(tSsid,0,sizeof(tSsid));PrintSSID(&rdBuffer, tSsid);tempInfo.sSsid=wstring(tSsid);tempInfo.nRssi=(int)pConfig->Rssi;tempInfo.InfrastructureMode=pConfig->InfrastructureMode;tempInfo.AuthenticationMode=pConfig->AuthenticationMode;tempInfo.ulPrivacy=pConfig->Privacy;if (WifiCallBack){WifiCallBack(tempInfo);}SsidList.push_back(tempInfo);}}
}取得無線網的SSID名稱
[cpp] view plaincopyprint? void PrintSSID // some RAW_DATA is a SSID, this function is for printing SSID ( PRAW_DATA prdSSID, // RAW SSID data WCHAR* tSsid ) { if (prdSSID == NULL || prdSSID->dwDataLen == 0) wprintf(L"<NULL>"); else { WCHAR szSsid[33]; MultiByteToWideChar(CP_ACP,0,(LPCSTR)prdSSID->pData,-1,tSsid,MAX_PATH*2); } } // PrintSSID()
void PrintSSID
// some RAW_DATA is a SSID, this function is for printing SSID
(PRAW_DATA prdSSID, // RAW SSID dataWCHAR* tSsid )
{if (prdSSID == NULL || prdSSID->dwDataLen == 0)wprintf(L"<NULL>");else{WCHAR szSsid[33];MultiByteToWideChar(CP_ACP,0,(LPCSTR)prdSSID->pData,-1,tSsid,MAX_PATH*2);}} // PrintSSID()
4.根據上面得到的信息，加上用戶輸入的密碼，生成的信息交給WINDOWS 的首選網絡列表 [cpp] view plaincopyprint?BOOL WirelessConnect(PTCHAR pCard, PTCHAR pSSID,NDIS_802_11_NETWORK_INFRASTRUCTURE infr, ULONG ulPrivacy, NDIS_802_11_AUTHENTICATION_MODE ndisMode, PTCHAR pKey,int iKeyIndex, int iEapType) //pCard: 無線網卡 GUID;pSSID: 無線AP SSID;bAdhoc: 是否點對點的 WIFI 連接;ulPrivacy: 加密模式(WEP/WPA....) ; //ndisMode: 認證模式(Open/Share);iKeyIndex: 密鑰索引(1-4);pKey: 密碼;iEapType: 802.11 認證模式 { ResetPreferredList(pCard); BOOL bRet = FALSE; if (!pSSID) { return FALSE; } else { WZC_WLAN_CONFIG wzcConfig; ZeroMemory(&wzcConfig, sizeof(WZC_WLAN_CONFIG)); wzcConfig.Length = sizeof(WZC_WLAN_CONFIG); wzcConfig.dwCtlFlags = 0; wzcConfig.Ssid.SsidLength = _tcslen(pSSID); for (UINT i = 0; i < wzcConfig.Ssid.SsidLength; i++) { wzcConfig.Ssid.Ssid[i] = (CHAR)pSSID[i]; } wzcConfig.InfrastructureMode = infr; wzcConfig.AuthenticationMode = ndisMode; wzcConfig.Privacy = ulPrivacy; if (pKey == NULL || _tcslen(pKey) == 0) { // 對密鑰進行轉換 bRet = InterpretEncryptionKeyValue(wzcConfig, 0, NULL, TRUE); wzcConfig.EapolParams.dwEapType = iEapType; wzcConfig.EapolParams.dwEapType =EAP_TYPE_TLS; wzcConfig.EapolParams.dwEapFlags = EAPOL_ENABLED; wzcConfig.EapolParams.bEnable8021x = TRUE; wzcConfig.EapolParams.dwAuthDataLen = 0; wzcConfig.EapolParams.pbAuthData = 0; } else { // RETAILMSG(DBG_MSG, (TEXT("WirelessConnect iKeyIndex = %d.\n"), iKeyIndex)); bRet = InterpretEncryptionKeyValue(wzcConfig, iKeyIndex, pKey, FALSE); } // 連接到指定的無線AP，并將該AP添加到首先無線AP中 AddToPreferredNetworkList(pCard, wzcConfig, pSSID); } return bRet; }

}
5.加入WINDOWS的首選網絡列表 [cpp] view plaincopyprint?void AddToPreferredNetworkList // adding to the [Preferred Networks] // [Preferred Networks] is a list of SSIDs in preference order. // WZC continuously scans available SSIDs and attempt to connect to the most preferable SSID.

連接WIFI網絡有這么幾個步驟，第一步，要獲取你自己的網卡，調用GetFirstWirelessNetworkCard()來實現。第二步，要獲得當前環境中的無線網信息，調用GetWirelessCardInfo來取得這些信息，調用GetWirelseeListSSID來解析這些信息，接下來把取得的無線網SSID和自己輸入的密碼用AddToPreferredNetworkList()傳到WINDOWS的首選無線網列表中，windows就會自動連接這個無線網絡。
下面是一整套通過WZC函數連接無線網的程序，我自己測試后保證可以運行，如有需要全部源碼或者動態庫文件的，請留言或者留下郵箱
調用WZC函數需要包含的文件和庫如下:
[cpp] view plaincopyprint?存放SSID的基本信息的數據結構: [cpp] view plaincopyprint?
接下來看關鍵函數的具體實現：
1.取得無線網卡
[cpp] view plaincopyprint?2.從無線網卡取得無線網絡信息 [cpp] view plaincopyprint?
3.解析這些信息，得到需要的無線網參數，ssid，信號強度，加密方式等等
4.根據上面得到的信息，加上用戶輸入的密碼，生成的信息交給WINDOWS 的首選網絡列表 [cpp] view plaincopyprint?
5.加入WINDOWS的首選網絡列表 [cpp] view plaincopyprint?
6.重置WINDOWS的首選網絡列表 [cpp] view plaincopyprint?
7.判斷網卡是否連接到了無線網絡 [cpp] view plaincopyprint?
8.密碼加密算法 [cpp] view plaincopyprint?
總結
