使用VBA获取可用的无线网络列表

VBA（Visual Basic for Applications）是一种用于自动化任务和编写宏的编程语言，常用于Microsoft Office套件中的应用程序，如Excel、Word和Access。在使用VBA获取可用的无线网络列表时，可以通过调用Windows操作系统的API函数来实现。

首先，需要在VBA中引入Windows API函数的声明，以便在代码中调用。以下是获取无线网络列表的基本步骤：

1. 引入API函数声明：Declare PtrSafe Function WlanOpenHandle Lib "wlanapi.dll" (ByVal dwClientVersion As Long, ByVal pReserved As Any, ByRef pdwNegotiatedVersion As Long, ByRef phClientHandle As LongPtr) As Long Declare PtrSafe Function WlanEnumInterfaces Lib "wlanapi.dll" (ByVal hClientHandle As LongPtr, ByVal pReserved As Any, ByRef ppInterfaceList As LongPtr) As Long Declare PtrSafe Function WlanGetAvailableNetworkList Lib "wlanapi.dll" (ByVal hClientHandle As LongPtr, ByVal pInterfaceGuid As Any, ByVal dwFlags As Long, ByVal pReserved As Any, ByRef ppAvailableNetworkList As LongPtr) As Long Declare PtrSafe Function WlanFreeMemory Lib "wlanapi.dll" (ByVal pMemory As LongPtr) As Long
2. 创建函数来获取无线网络列表：Function GetAvailableNetworks() As String Dim hClientHandle As LongPtr Dim dwNegotiatedVersion As Long Dim pInterfaceList As LongPtr Dim pAvailableNetworkList As LongPtr Dim i As Long Dim ssid As String ' 打开WLAN客户端句柄 If WlanOpenHandle(2, 0, dwNegotiatedVersion, hClientHandle) = 0 Then ' 获取接口列表 If WlanEnumInterfaces(hClientHandle, 0, pInterfaceList) = 0 Then ' 获取可用的网络列表 If WlanGetAvailableNetworkList(hClientHandle, ByVal pInterfaceList, 0, 0, pAvailableNetworkList) = 0 Then ' 解析网络列表 Dim pNetworkList As WLAN_AVAILABLE_NETWORK_LIST pNetworkList = CopyMemoryToStruct(pAvailableNetworkList, pNetworkList) For i = 0 To pNetworkList.dwNumberOfItems - 1 ssid = pNetworkList.Network[i].dot11Ssid.ucSSID ' 处理获取到的无线网络名称 ' 可以将其添加到列表框或输出到单元格等 Debug.Print ssid Next i ' 释放内存 WlanFreeMemory pAvailableNetworkList End If End If End If ' 关闭WLAN客户端句柄 WlanCloseHandle hClientHandle, 0 GetAvailableNetworks = "获取无线网络列表完成" End Function
3. 定义结构体以便解析网络列表：Private Type DOT11_SSID ucSSID(31) As Byte uSSIDLength As Long End Type Private Type WLAN_AVAILABLE_NETWORK strProfileName(511) As Byte dot11Ssid As DOT11_SSID dot11BssType As Long uNumberOfBssids As Long bNetworkConnectable As Boolean wlanNotConnectableReason As Long uNumberOfPhyTypes As Long dot11PhyTypes(7) As Long bMorePhyTypes As Boolean wlanSignalQuality As Long bSecurityEnabled As Boolean dot11DefaultAuthAlgorithm As Long dot11DefaultCipherAlgorithm As Long dwFlags As Long dwReserved As Long End Type Private Type WLAN_AVAILABLE_NETWORK_LIST dwNumberOfItems As Long dwIndex As Long Network() As WLAN_AVAILABLE_NETWORK End Type
4. 辅助函数用于复制内存到结构体：Function CopyMemoryToStruct(ByVal pSource As LongPtr, ByRef dest As Any) As Any Dim cbSize As Long cbSize = LenB(dest) CopyMemory ByVal VarPtr(dest), ByVal pSource, cbSize CopyMemoryToStruct = dest End Function Private Declare PtrSafe Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (ByVal Destination As LongPtr, ByVal Source As LongPtr, ByVal Length As Long)

以上代码通过调用Windows WLAN API函数，获取无线网络列表并输出到调试窗口。你可以根据需要将获取到的无线网络名称进行进一步处理，例如将其添加到列表框或输出到单元格中。

请注意，以上代码仅适用于Windows操作系统，并且需要在VBA中启用对API函数的访问。此外，具体的应用场景和推荐的腾讯云相关产品和产品介绍链接地址需要根据实际需求和腾讯云的服务提供进行选择和提供。
