如何检索此计算机的IP地址？

Question

什么是最简单的（模块包含，代码长度等）方式来检索机器IP地址（第一个接口打开）？我知道使用MSINET的一些解决方案，但我相信我们可以做得更好。不要回复

Function HomeIP() as Atring
HomeIP= "127.0.0.1"
End Function

因为它不那么有趣......或者说是正确的。这个场景是一个qazxsw poi的问题，我正在尝试建立一个回复。

Answer 1

以下是document ID feature的改编示例：

Technet

它要求您在项目的引用中包含Microsoft WMI Scripting Library。

Answer 2

我找到了几个例子： -

Function GetIPAddress()
    Const strComputer As String = "."   ' Computer name. Dot means local computer
    Dim objWMIService, IPConfigSet, IPConfig, IPAddress, i
    Dim strIPAddress As String

    ' Connect to the WMI service
    Set objWMIService = GetObject("winmgmts:" _
        & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")

    ' Get all TCP/IP-enabled network adapters
    Set IPConfigSet = objWMIService.ExecQuery _
        ("Select * from Win32_NetworkAdapterConfiguration Where IPEnabled=TRUE")

    ' Get all IP addresses associated with these adapters
    For Each IPConfig In IPConfigSet
        IPAddress = IPConfig.IPAddress
        If Not IsNull(IPAddress) Then
            strIPAddress = strIPAddress & Join(IPAddress, ", ")
        End If
    Next

    GetIPAddress = strIPAddress
End Function

还有另一种使用ipconfig的简单方法。 ipconfig

Codeproject有一篇关于如何使用.net：http://www.vbaexpress.com/kb/getarticle.php?kb_id=537执行此操作的文章

您总是可以创建一个控制台可执行文件，并从VBA调用它。

Answer 6

无论如何，http://www.codeproject.com/KB/cs/network.aspx可能会在XP上完成这项工作。不确定其他Windows版本或其他语言的本地化。部分样本输出：

C：\ Documents and Settings \ colin> nbtstat -n

本地连接：节点IpAddress：[192.168.1.100]范围ID：[]

nbtstat -n

等等
