使用vbRichClient代替winsock，实现局网多客户端非gui数据收发

发现网上关于vbrichclient的教程比较少，但这个实在是好东西，实用性，稳定性都比VB自带的winsock好的多，多客户端不用winsock控件数组。　也不用在各窗体上放winsock，直接在模块中就能实现收发 下面直接上代码，窗体和文本钮、按钮大家自行拖放。要用到VB自带隐藏函数varptr()取内存指针(VbMsdn中没有这个函数，实际上很简单^^)。 VbRichClient5.0.38中包含sqlite3.9支持 上面共享中也包含VbRichClient5.0.38支持库 VbRichClient代替winsock 主要使用 cTCPServer cTCPClient cUDP '--------------------------------------------------------------------- '服务器端，代码最简化，要实现多客户端只要用数组存hsocket就可以 Option Explicit Dim WithEvents sv As cTCPServer Dim WithEvents udp1 As cUDP Dim cHsocket& Private Sub Form_Load() Set sv = New cTCPServer sv.Listen sv.GetHost("127.0.0.1"), 35912 Debug.Print sv.GetHost("") Set udp1 = New cUDP udp1.Bind "127.0.0.1", 5616 End Sub Private Sub sv_DataArrival(ByVal hSocket As Long, ByVal BytesTotal As Long, ByVal FirstBufferAfterOverflow As Boolean) Dim d() As Byte, s$ ReDim d(BytesTotal - 1) sv.GetData hSocket, VarPtr(d(0)), BytesTotal '★★关键代码 s = d Text2.Text = Text2.Text & s & vbCrLf Debug.Print "收到：" & BytesTotal End Sub Private Sub sv_TCPAccepted(ByVal hSocket As Long) cHsocket = hSocket Text1.Text = Text1.Text & sv.GetPeerHostIPAndPort(hSocket) & vbCrLf End Sub Private Sub sv_TCPDisConnect(ByVal hSocket As Long) Text3.Text = Text3.Text & sv.GetPeerHostIPAndPort(hSocket) & vbCrLf End Sub Private Sub udp1_NewDatagram(ByVal BytesTotal As Long, ByVal FirstBufferAfterOverflow As Boolean) Dim d() As Byte, s$ ReDim d(BytesTotal - 1) udp1.GetData VarPtr(d(0)), BytesTotal s = d Text2.Text = Text2.Text & s & vbCrLf End Sub '------------------------------------------------------- '客户端 Option Explicit Dim WithEvents cl As cTCPClient Dim WithEvents udp1 As cUDP Dim cid& Private Sub Command1_Click() cid = cl.Connect("QgB1", 35912) End Sub Private Sub Command2_Click() cl.Disconnect cid End Sub Private Sub Command3_Click() Dim b() As Byte b = Text1.Text cl.SendData cid, VarPtr(b(0)), UBound(b) + 1 End Sub Private Sub Command4_Click() Dim d() As Byte, s$ s = "yessss" d = s udp1.RemoteIP = "127.0.0.1" udp1.RemotePort = 5616 u
