VB 修改 IP地地址
你要问的是不是以上三项在注册表中的位置,下面提供:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces
项下有很多句柄你可以在里边找到不同的本地连接对应的句柄,在程序里进行修改就可以了,如果找不到,可以先在本地连接属性里修改tcp/ip协议的相应设置,然后到注册表里查找相应的数据就可以定位该位置了!源码这次就不给出了,就是修改注册表,和容易,您可以使用vb自带的函数,也可以使用wsh提供的脚本函数,当然也可以使用winAPI(比较复杂,要严格定义参数类型,即缓冲区,所以简单的修改不建议使用)。
希望您的问题能尽快解决!
VB.NET的TCP/IP协议 怎么弄
Dim th As Threading.Thread
2 Dim tcpl As System.Net.Sockets.TcpListener
3
4 Private Sub Form1_Load()Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
5 th = New System.Threading.Thread(New System.Threading.ThreadStart(AddressOf MyListen))
6 th.Start()
7 End Sub
8
9 Public Sub SendMessage()Sub SendMessage(ByVal IP As String, ByVal SendMsg As String)
10 Try
11 If IP "" Then
12 Dim tcpc As New System.Net.Sockets.TcpClient(IP, 5656)
13 Dim tcpStream As Net.Sockets.NetworkStream = tcpc.GetStream
14 Dim reqStream As New IO.StreamWriter(tcpStream)
15 reqStream.Write(SendMsg)
16 reqStream.Flush()
17 tcpStream.Close()
18 tcpc.Close()
19 End If
20 Catch ex As Exception
21 MsgBox(ex.Message.ToString)
22 End Try
23 End Sub
24 Private Sub MyListen()Sub MyListen()
25 Try
26 Dim ipAddress As System.Net.IPAddress = System.Net.Dns.Resolve(System.Net.Dns.GetHostName).AddressList(0)
27 tcpl = New System.Net.Sockets.TcpListener(ipAddress, 5656)
28 tcpl.Start()
29 While True
30 Dim s As System.Net.Sockets.Socket = tcpl.AcceptSocket()
31 Dim MyBuffer(1024) As Byte
32 Dim i As Integer
33 i = s.Receive(MyBuffer)
34 If i 0 Then
35 Dim lstrRec As String
36 Dim j As Integer
37 For j = 0 To i - 1
38 TextBox1.Text += Chr(MyBuffer(j)) ","
39 Next
40 End If
41 End While
42 Catch ex As Exception
43 MsgBox(ex.Message.ToString)
44 End Try
45 End Sub
46
47 Private Sub Button1_Click()Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
48 SendMessage("192.168.0.61", TextBox2.Text)
49 End Sub
如何在vb,net用程序修改ip地址
做exe程序获取本机IP地址用
System.Net.Dns.GetHostByName(System.Net.Dns.GetHostName()).AddressList
做web程序获取客户端的IP地址用
HttpContext.Current.Request.ServerVariables("REMOTE_ADDR"])

建议你使用注册表的API进行修改
封装两个NET函数给你
private string GetReg(string RegPath) 取得注册表项内容
{
string str="";
RegistryKey hkml = Registry.LocalMachine;
RegistryKey software = hkml.OpenSubKey("SOFTWARE",true);
RegistryKey aimdir = software.OpenSubKey("krabs",true);
if (aimdir != null)
{
if (aimdir.GetValue(RegPath) != null)
str = aimdir.GetValue(RegPath).ToString();
if (str != null)
return str;
return null;
}
return null;
}
private bool SetReg(string RegPath,string Data) //设置注册表内容
{
RegistryKey reg = Registry.LocalMachine;
RegistryKey software = reg.OpenSubKey("SOFTWARE", true);
RegistryKey aimdir1 = software.CreateSubKey("krabs");
if (aimdir1 == null)
return false;
aimdir1.SetValue(RegPath, Data);
return true;
}
