如何在VB中获得本机的ip地址

vb中如何获取本机ip地址~

定义以下过程即可获取本机ip地址
Sub GetMyIP() Dim strComputer As String Dim objWMI As Object Dim colIP As Object Dim IP As Object Dim I As Integer strComputer = "." Set objWMI = GetObject("winmgmts://" & strComputer & "/root/cimv2") Set colIP = objWMI.ExecQuery _ ("Select * from Win32_NetworkAdapterConfiguration where IPEnabled=TRUE") For Each IP In colIP If Not IsNull(IP.IPAddress) Then For I = LBound(IP.IPAddress) To UBound(IP.IPAddress) MsgBox "IP 地址:" & IP.IPAddress(I) & Chr(10) & _ Next End If NextEnd Sub

建议用API函数，以下完整示例：
（其中直接调用GetIPAddress函数即可获取IP）
