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。

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:

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

{

ULONG ulPrivacy;

接下來看關鍵函數的具體實現：

1.取得無線網卡

[cpp] view plaincopyprint?

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
