这篇文章主要讲解了" VC++ win7下怎么实现WIFI共享工具"，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习" VC++ win7下怎么实现WIFI共享工具"吧！

关于无线承载网络

无线承载网络(Wireless Hosted Network)是指安装有无线局域网服务的Windows 7和Windows Server 2008 R2所提供的一种WLAN功能，具备两项主要功能：

第一、把一个物理无线网卡虚拟化成一个或多个虚拟无线网卡，称为虚拟的WiFi。

第二、借助无线网卡把当前接网络虚拟成为一个基于软件的无线接入点，称为虚拟AP或软AP。

=========================万恶的分割线===========================

项目需要包含wlanapi.h 头文件和wlanapi.lib 库

备注：测试环境win7_64,建议关闭一些安全软件，（比如我测试的时候忘了关comodo导致防火墙总是拒绝其他设备的连接）。

=============================================================

功能不复杂，用到的主要函数有下面几个

1.调用WlanOpenHandled得到一个连接hClientHandle，下面的操作都要用到这个连接。当然程序退出的时候记得调用WlanCloseHandle关闭这个连接。

DWORD WINAPI WlanOpenHandle(  _In_        DWORD dwClientVersion,  _Reserved_  PVOID pReserved,  _Out_       PDWORD pdwNegotiatedVersion,  _Out_       PHANDLE phClientHandle);DWORD WINAPI WlanCloseHandle(  _In_        HANDLE hClientHandle,  _Reserved_  PVOID pReserved);

2.下面的函数用来设置承载网络的一些属性。

DWORD WINAPI WlanHostedNetworkSetProperty(  _In_        HANDLE hClientHandle,  _In_        WLAN_HOSTED_NETWORK_OPCODE OpCode,  _In_        DWORD dwDataSize,  _In_        PVOID pvData,  _Out_opt_   PWLAN_HOSTED_NETWORK_REASON pFailReason,  _Reserved_  PVOID pvReserved);typedef enum _WLAN_HOSTED_NETWORK_OPCODE {   wlan_hosted_network_opcode_connection_settings,          //设置一些连接属性  wlan_hosted_network_opcode_security_settings,            //设置安全属性  wlan_hosted_network_opcode_station_profile,              //query the wireless Hosted Network station profile  wlan_hosted_network_opcode_enable                        //query or set the wireless Hosted Network enabled flag} WLAN_HOSTED_NETWORK_OPCODE, *PWLAN_HOSTED_NETWORK_OPCODE;

3.启用和禁用无线承载网络。

打开网络和共享中心单击更改适配器设置，如果启用了无线承载网络面板里面就会有描述为Microsoft Virtual WiFi Miniport Adapter的一个虚拟网卡。禁用之后这个虚拟网卡就会消失了。

当然只有启用了无线承载网络才能分享wifi啦

DWORD WINAPI WlanHostedNetworkForceStart(  _In_        HANDLE hClientHandle,  _Out_opt_   PWLAN_HOSTED_NETWORK_REASON pFailReason,  _Reserved_  PVOID pvReserved);

DWORD WINAPI WlanHostedNetworkForceStop(  _In_        HANDLE hClientHandle,  _Out_opt_   PWLAN_HOSTED_NETWORK_REASON pFailReason,  _Reserved_  PVOID pvReserved);

4.连接和断开网络

DWORD WINAPI WlanHostedNetworkStartUsing(  _In_        HANDLE hClientHandle,  _Out_opt_   PWLAN_HOSTED_NETWORK_REASON pFailReason,  _Reserved_  PVOID pvReserved);

DWORD WINAPI WlanHostedNetworkStopUsing(  _In_        HANDLE hClientHandle,  _Out_opt_   PWLAN_HOSTED_NETWORK_REASON pFailReason,  _Reserved_  PVOID pvReserved);

5.用来查询承载网络的网络状况。

DWORD WINAPI WlanHostedNetworkQueryStatus(  _In_        HANDLE hClientHandle,  _Out_       PWLAN_HOSTED_NETWORK_STATUS *ppWlanHostedNetworkStatus,  _Reserved_  PVOID pvReserved);

typedef struct _WLAN_HOSTED_NETWORK_STATUS {  WLAN_HOSTED_NETWORK_STATE      HostedNetworkState;  GUID                           IPDeviceID;  DOT11_MAC_ADDRESS              wlanHostedNetworkBSSID;  DOT11_PHY_TYPE                 dot11PhyType;  ULONG                          ulChannelFrequency;  DWORD                          dwNumberOfPeers;            //已连接的节点数目  WLAN_HOSTED_NETWORK_PEER_STATE PeerList[1];                //存放节点信息的数组} WLAN_HOSTED_NETWORK_STATUS, *PWLAN_HOSTED_NETWORK_STATUS;typedef struct _WLAN_HOSTED_NETWORK_PEER_STATE {  DOT11_MAC_ADDRESS                   PeerMacAddress;        //节点设备的MAC地址  WLAN_HOSTED_NETWORK_PEER_AUTH_STATE PeerAuthState;            //节点的认证状态} WLAN_HOSTED_NETWORK_PEER_STATE, *PWLAN_HOSTED_NETWORK_PEER_STATE;

调用WlanHostedNetworkQueryStatus将得到一个WLAN_HOSTED_NETWORK_STATUS结构体，就可以查询一些网络基本信息了，比如dwNumberOfPeers连接到这个网络的节点数，PeerList数组存放着对应节点的详细信息，包括MAC地址和认证状态。

6.用来设置密码

注意密码长度必须大于8 小于63 否则会调用失败

DWORD WINAPI WlanHostedNetworkSetSecondaryKey(  _In_        HANDLE hClientHandle,  _In_        DWORD dwKeyLength,  _In_        PUCHAR pucKeyData,  _In_        BOOL bIsPassPhrase,  _In_        BOOL bPersistent,  _Out_opt_   PWLAN_HOSTED_NETWORK_REASON pFailReason,  _Reserved_  PVOID pvReserved);
