vb.net连接wifi vb net

使用vb.net将以太网共享给虚拟wifi网络最简单的办法是用句柄操作窗体,这种方法就好比是计算机在代替你在打开设置窗口,完成设置 。
比较难实现的方法是用API,不过我不知道用那些API,而且还要驱动支持
因为vb 。net是高级语言,不能直接操作驱动,所以直接写汇编是不可行的
VB.Net 关于路由器后TCP或UDP通讯问题 假设一台电脑192.168.0.1位于路由1.端口不NAT,两个子网中的两端之间不可能通信 。至少要有一方处在公网下或有路由端口映射,不必双方都映射 。
建议题主找本计算机网络的书研读一下子网划分这块儿 。
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
【vb.net连接wifi vb net】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
46
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
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 。
VB.NET如何判断电脑是否已连接到网络?Microsoft.VisualBasic.Devices.Network.IsAvailable As Boolean
生成实例后可以通过此属性来获取是否联网的值,True代表已联网,False代表没有联网
Microsoft.VisualBasic.Devices.Network.NetworkAvailabilityChanged(ByVal Object, ByVal Microsoft.VisualBasic.Devices.NetworkAvailableEventArgs)
该事件是在电脑断开/连上互联网是引发的
其中:
e.IsNetworkAvailable
的功能同Microsoft.VisualBasic.Devices.Network.IsAvailable
实例:
Dim netListener As New Microsoft.VisualBasic.Devices.Network '生成实例
If netListener.IsAvailable = True Then
MsgBox("已联网")
Else
MsgBox("未联网")
End If
NetworkAvailabilityChanged实例:
WithEvents netListener As New Microsoft.VisualBasic.Devices.Network '生成实例
Private Sub OnNetworkChanged(ByVal Object, ByVal Microsoft.VisualBasic.Devices.NetworkAvailableEventArgs)Handles netListener.NetworkAvailabilityChanged
If e.IsNetworkAvailable = True Then
MsgBox("已联网")
Else
MsgBox("未联网")
End If
End Sub
