前段时间看到有会员要获取IP地址，而自己曾经也想实现这个，虽然目前还没有在实际应用中用到，不过在业余时间还是自己尝试实现一下，随便也提供给有这个需求的会员：
为了实现这个功能，还是单独创建一个Script库吧，命名为LocalIP,将以下声名放到(Declarations)里
Private Const WS_VERSION_REQD = &H101
Private Const WS_VERSION_MAJOR = WS_VERSION_REQD \ &H100 And &HFF&
Private Const WS_VERSION_MINOR = WS_VERSION_REQD And &HFF&
Private Const MIN_SOCKETS_REQD = 1
Private Const SOCKET_ERROR = -1
Private Const WSADescription_Len = 256
Private Const WSASYS_Status_Len = 128
Private Type HOSTENT
hName As Long
hAliases As Long
hAddrType As Integer
hLength As Integer
hAddrList As Long
End Type
Private Type WSADATA
wversion As Integer
wHighVersion As Integer
szDescription(0 To WSADescription_Len) As Byte
szSystemStatus(0 To WSASYS_Status_Len) As Byte
iMaxSockets As Integer
iMaxUdpDg As Integer
lpszVendorInfo As Long
End Type
Declare Function WSAGetLastError Lib "WSOCK32.DLL" () As Long
Declare Function WSAStartup Lib "WSOCK32.DLL" (Byval wVersionRequired As Integer, lpWSAData As WSADATA) As Long
Declare Function WSACleanup Lib "WSOCK32.DLL" () As Long
Declare Function gethostname Lib "WSOCK32.DLL" (Byval hostname$,Byval HostLen As Long) As Long
Declare Function gethostbyname Lib "WSOCK32.DLL" (Byval hostname$) As Long
Declare Sub RtlMoveMemory Lib "KERNEL32" (hpvDest As Any, Byval hpvSource&, Byval cbCopy&)
以下一些相关函数:
这是用户调用的函数
Function GetLocalIPAddress() As Variant
%REM
功能：获得本机IP地址
%END REM
Dim hostname As String * 256
Dim hostent_addr As Long
Dim host As HOSTENT
Dim hostip_addr As Long
Dim temp_ip_address() As Byte
Dim i As Integer
Dim ip_address As String
If gethostname(hostname, 256) = SOCKET_ERROR Then
Msgbox "Windows Sockets error " & Str(WSAGetLastError())
Exit Function
Else
hostname = Trim$(hostname)
End If
hostent_addr = gethostbyname(hostname)
If hostent_addr = 0 Then
Msgbox "Winsock.dll is not responding."
Exit Function
End If
RtlMoveMemory host, hostent_addr, Lenb(host)
RtlMoveMemory hostip_addr, host.hAddrList, 4
Msgbox hostname
'get all of the IP address if machine is multi-homed
Do
Redim temp_ip_address(1 To host.hLength)
RtlMoveMemory temp_ip_address(1), hostip_addr, host.hLength
For i = 1 To host.hLength
ip_address = ip_address & temp_ip_address(i) & "."
Next
ip_address = Mid$(ip_address, 1, Len(ip_address) - 1)
Msgbox ip_address
ip_address = ""
host.hAddrList = host.hAddrList + Lenb(host.hAddrList)
RtlMoveMemory hostip_addr, host.hAddrList, 4
Loop While (hostip_addr <> 0)
End Function
Function hibyte(Byval wParam As Integer)
hibyte = wParam \ &H100 And &HFF&
End Function
Function lobyte(Byval wParam As Integer)
lobyte = wParam And &HFF&
End Function
Function SocketsInitialize()
Dim WSAD As WSADATA
Dim iReturn As Integer
Dim sLowByte As String, sHighByte As String, sMsg As String
iReturn = WSAStartup(WS_VERSION_REQD, WSAD)
If iReturn <> 0 Then
Msgbox "Winsock.dll is not responding."
End
End If
If lobyte(WSAD.wversion) <WS_VERSION_MAJOR Or (lobyte(WSAD.wversion) = _
WS_VERSION_MAJOR And hibyte(WSAD.wversion) < WS_VERSION_MINOR) Then
sHighByte = Trim$(Str$(hibyte(WSAD.wversion)))
sLowByte = Trim$(Str$(lobyte(WSAD.wversion)))
sMsg = "Windows Sockets version " & sLowByte & "." & sHighByte
sMsg = sMsg & " is not supported by winsock.dll "
Msgbox sMsg
End
End If
'iMaxSockets is not used in winsock 2. So the following check is only
'necessary for winsock 1. If winsock 2 is requested,
'the following check can be skipped.
If WSAD.iMaxSockets < MIN_SOCKETS_REQD Then
sMsg = "This application requires a minimum of "
sMsg = sMsg & Trim$(Str$(MIN_SOCKETS_REQD)) & " supported sockets."
Msgbox sMsg
End
End If
End Function
Function SocketsCleanup()
Dim lReturn As Long
lReturn = WSACleanup()
If lReturn <> 0 Then
Msgbox "Socket error " & Trim$(Str$(lReturn)) & " occurred in Cleanup "
End
End If
End Function
Function Form_Load()
SocketsInitialize
End Function
Function Form_Unload(Cancel As Integer)
SocketsCleanup
End Function
用户可以在表单按钮或者操作将此Script库引用，然后运行函数就可以,其实这是微软针对VB获取IP地址的方案，我只不过用在Notes里，并相应处理一下，
