这里有个例子：
一·Winsock的主要属性、事件和方法Winsock是不可见控件，控件文件名是MSWINSCK.OCX，全称为Mcirosoft winsock control，使用时要将此控件调入工具箱。1·属性：①Protocol=0 //使用TCP协议；②RemoteHost //准备连接远程机的IP地址③RemotePort //连接远程机的IP端口号 （1024—65535之间）④LocalPort //本地机监听IP端口号必须与呼叫机端口号相同2·方法：①connect //申请连接远程机②listen //设置监听③accept //建立实际连接④senddata //发送数据⑤getdata //接收数据⑥close //关闭连接3·事件：①connectionrequest //一方请求连接时另一方产生②connect //一方机接受连接时另一方产生③close //一方机关闭连接时另一方产生④dataArrival //一方发送数据另一方产生⑤error //请求连接失败时产生二·制作方法⑴ 在一工程中添加两个表单form1（模拟客户端）、form2（模拟服务器端）。form1中装入控件：控件名
主要属性

Text1的框标MSWinsocklib.Winsock a用于监听MSWinsocklib.Winsock b用于传送聊天信息
⑵ 在Form1的各控件事件中加入如下代码:Dim flag As Boolean 注释：连接状态变量Private Sub a_Connect()flag = TrueEnd SubPrivate Sub a_DataArrival(ByVal bytesTotal As Long)Dim i As Stringa.GetData iLabel3.Caption = "连接成功！"Comm2.MousePointer = 0Form1.MousePointer = 0Timer1.Enabled = FalseIf i = Chr(0) ThenText2.Text = "你是今天第一个进入本聊天室的客户。" + Chr(13) + Chr(10)ElseText2.Text = Text2.Text + iEnd IfText2.SelStart = Len(Text2.Text)Send.MousePointer = 0Combo1.Enabled = FalseComm2.Caption = "断开连接"Text1.SetFocusEnd SubPrivate Sub a_Error(ByVal Number As Integer, Description As String, ByVal Scode As Long, ByVal Source As String, ByVal HelpFile As String, ByVal HelpContext As Long, CancelDisplay As Boolean)flag = FalseTimer1.Enabled = FalseComm2.MousePointer = 0Form1.MousePointer = 0MsgBox "网络连接失败！"Label3.Caption = "等待连接"Combo1.Enabled = TrueCombo1.SetFocusa.CloseComm2.Caption = "连接"End SubPrivate Sub Comm1_Click()a.Close 注释：关闭连接Form1.WindowState = 1End SubPrivate Sub Comm2_Click()If Comm2.Caption = "断开连接" Thena.CloseComm2.Caption = "连接"Label3.Caption = "等待连接"Combo1.Enabled = TrueTimer1.Enabled = FalseComm2.MousePointer = 0Form1.MousePointer = 0ElseText2.Text = ""Label3.Caption = "正在连接.."Comm2.MousePointer = 11Form1.MousePointer = 11Timer1.Enabled = Trueflag = Falsea.Protocol = sckTCPProtocola.RemoteHost = Combo1.Texta.RemotePort = 3000a.ConnectEnd IfEnd SubPrivate Sub Form_DblClick()If MsgBox("关闭本聊天室! 确认吗？", 36, "退出系统") = 6 ThenEndElseForm1.WindowState = 1End IfEnd SubPrivate Sub Form_Load()If App.PrevInstance ThenMsgBox "本系统已经加载，请看任务拦！", 48, "提示"EndEnd Ifflag = FalseLoad Form2 ‘读入form2进入监听End SubPrivate Sub Send_Click()Dim S As StringOn Error GoTo ffff ‘防止链路中断Send.MousePointer = 11If Right(Text1.Text, 1) <> Chr(10) ThenS = Text1.Text + Chr(13) + Chr(10)ElseS = Text1.TextEnd IfIf flag Thena.SendData SEnd IfExit Subffff:MsgBox "连接中断!", 48, "提示"a.CloseSend.MousePointer = 0Comm2.Caption = "连接"Label3.Caption = "等待连接"Combo1.Enabled = TrueComm2.MousePointer = 0Form1.MousePointer = 0Exit SubEnd SubPrivate Sub Timer1_Timer()flag = FalseTimer1.Enabled = FalseComm2.MousePointer = 0Form1.MousePointer = 0MsgBox "网络连接失败(超时) ！"Label3.Caption = "等待连接"Combo1.Enabled = TrueCombo1.SetFocusa.CloseComm2.Caption = "连接"End Sub⑶ 在Form2的各控件事件中加入如下代码:Const maxn = 200 ‘最大同时连接本机的客户数Dim user(maxn) As BooleanPrivate Sub Command1_Click()Form2.HideEnd SubPrivate Sub Command2_Click()Load Form1Form1.ShowEnd SubPrivate Sub Form_Load()Dim str1 As StringForm2.Caption = "雷萌通信软件"注释：winsock控件 a 作为服务器程序监听a.LocalPort = 3000a.ListenEnd SubPrivate Sub a_ConnectionRequest(ByVal requestID As Long)Dim i As LongFor i = 1 To maxn ‘当一客户请求时给启动一Winsock控件标志号If Not user(i) Thenuser(i) = TrueExit ForEnd IfNext iIf i > maxn ThenExit SubEnd IfLoad b(i) ‘当一客户请求时启动一Winsock控件b(i).Accept requestID 注释：实际建立连接If Text1.Text = "" Then 注释：发送数据b(i).SendData Chr(0)Elseb(i).SendData Text1.TextEnd IfForm2.ShowEnd SubPrivate Sub s_Close(Index As Integer)b(Index).Close 注释：关闭连接Unload b(Index) 注释：卸载 一个WinSock 控件user(Index) = FalseEnd SubPrivate Sub b_DataArrival(Index As Integer, ByVal bytesTotal As Long)Dim str As StringDim i As Longb(Index).GetData strText1.Text = Text1.Text + strFor i = 1 To maxnIf user(i) Thenb(i).SendData strEnd IfNext iEnd Sub三·运行本程序在VB6.0中编译通过，运行后最小化到任务栏上，也可以用API的Shell_Notifyicon 函数做入右下角的指示器栏中常驻内存。你可以在网络中用一个固定的机器地址作为聊天讨论室，其他用户都选该机地址连接进入该室聊天或讨论。各用户也可选各自熟悉的地址进行连接对话,双击form1空白处从内存中撤出系统。
