请问如何使用Winsock控件发送，接送文件？最好给出个例子!谢谢!

用Winsock传递数据时，是一种C/S程序
服务器：
Option Explicit
Private Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, ByVal x As Long, ByVal y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long
Dim Ws_I As Integer
Dim Yb(100) As String

Private Sub Form_Load()
SetWindowPos Me.hwnd, -1, 0, 0, 0, 0, &H2 Or &H1
Ws1(0).LocalPort = 1001
Ws_I = 0
Ws1(0).Listen
End Sub

Private Sub Ws1_Close(Index As Integer)
Yb(Index) = ""
End Sub

Private Sub Ws1_ConnectionRequest(Index As Integer, ByVal requestID As Long)
Ws_I = Ws_I + 1
Load Ws1(Ws_I)
Ws1(Ws_I).Accept requestID
List1.AddItem Ws_I
End Sub

Private Sub Ws1_DataArrival(Index As Integer, ByVal bytesTotal As Long)
Dim Str As String
Ws1(Index).GetData Str, vbString
Ws1(GetId(Str)).SendData GetNeiRong(Str)
List1.AddItem Str
End Sub

客户端：

Option Explicit
Private Sub Cmd_Send_Click()
On Error GoTo out
Ws1.SendData T1.Text & " " & Id
Exit Sub
out:
MsgBox "你要聊的对象已退出！", vbInformation, "警告"
Unload Me
End Sub

Private Sub Form_Load()
Ws1.RemoteHost = "yangbo"
Ws1.RemotePort = 1001
Ws1.Connect
End Sub

Private Sub Ws1_DataArrival(ByVal bytesTotal As Long)
Dim str As String
Ws1.GetData str, vbString
List1.AddItem str
End Sub

Public Sub Yb_Show(Key As Integer)
Id = Key
Me.Show
End Sub
以上事例中便有传递数据的方法，你只需改改IP即可
