1、安装vs.net软件(选默认语言是vb.net),安装iis服务器,安装数据库
2、运行vs.net软件,新建asp.net网站,写好网页。需要具备的知识点有html+div、javascript、jqurey、AJAX、vb.net、数据库的操作等。
3、在网上购买一个网站虚拟空间,购买一个域名,发布自已做好的网站上去就OK了
用 vb.net socket通信
Dim th As Threading.Thread

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()

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()

31 Dim MyBuffer(1024) As Byte

47 Private Sub Button1_Click()Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

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
