vb.net多网卡监听 tcpdump监听所有网卡

IT技术控件

vb.net 获取指定网卡的网络连接状态.net不能获得【指定】网卡的信息，给个思路，先遍历所有网卡，然后找到你需要的的那个网卡的信息 。
用vb.net实现网络通信用 vb.net socket通信
Dim th As Threading.Thread
2Dim tcpl As System.Net.Sockets.TcpListener
3
4Private Sub Form1_Load()Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
5th = New System.Threading.Thread(New System.Threading.ThreadStart(AddressOf MyListen))
6th.Start()
7End Sub

9Public Sub SendMessage()Sub SendMessage(ByVal IP As String, ByVal SendMsg As String)
10Try
11If IP"" Then
12Dim tcpc As New System.Net.Sockets.TcpClient(IP, 5656)
13Dim tcpStream As Net.Sockets.NetworkStream = tcpc.GetStream
14Dim reqStream As New IO.StreamWriter(tcpStream)
15reqStream.Write(SendMsg)
16reqStream.Flush()
17tcpStream.Close()
18tcpc.Close()
19End If
20Catch ex As Exception
21MsgBox(ex.Message.ToString)
22End Try
23End Sub
24Private Sub MyListen()Sub MyListen()
25Try
26Dim ipAddress As System.Net.IPAddress = System.Net.Dns.Resolve(System.Net.Dns.GetHostName).AddressList(0)
27tcpl = New System.Net.Sockets.TcpListener(ipAddress, 5656)
28tcpl.Start()
29While True
30Dim s As System.Net.Sockets.Socket = tcpl.AcceptSocket()
31Dim MyBuffer(1024) As Byte
32Dim i As Integer
33i = s.Receive(MyBuffer)
34If i0 Then
35Dim lstrRec As String
36Dim j As Integer
37For j = 0 To i - 1
38TextBox1.Text += Chr(MyBuffer(j))","
39Next
40End If
41End While
42Catch ex As Exception
43MsgBox(ex.Message.ToString)
44End Try
45End Sub

47Private Sub Button1_Click()Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
48SendMessage("192.168.0.61", TextBox2.Text)
49End Sub
电脑有两张网卡 。如何用vb.net分别获取网卡的IP?求大神明路！'要使得引用System.Management有效，先通过菜单
'[项目]--[添加引用]，在“.Net”选项卡里 ， 选择“System.Management”，单击[确定]
Imports System.Management
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim MySearcher As New ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration")
For Each MySearcherObj As ManagementObject In MySearcher.Get
If CBool(MySearcherObj("IPEnabled")) Then
MsgBox(MySearcherObj("IPAddress")(0))
End If
Next
End Sub
End Class
vb.net从一台主机通过socket同时向多台主机传送信息，如何操作？用VB5 Winsock控件创建TCP/IP通讯程序随着Windows 95中文版和Windows NT Server 4.0中文版的流行，Microsoft公司推出了相应平台上的开发软件: Visual Basic 5.0 中文企业 版 。它为Windows环境下的网络开发提供了强大的工具 ， Winsock控件就是其中之一 。Winsock控件建立在TCP、UDP协议的基础上 ， 完成与远程计算机的通信 。即使对TCP/IP不太熟悉的用户 ， 使用该控件也可以在十几分钟内创建一个简单的客户机/服务器程序 。下面我们对Winsock控件的事件、方法、属性按其在程序中出现的顺序分别作详细的介绍，以便更好地理解程序源代码 。
