利用VB6實現(xiàn)客戶端與服務(wù)端傳輸文件
━━━━━━━━━━━━━━━━━━━━━━━━━

如果文件大的話，一定不要大于8k
一個例子我自己做的，基本沒有問題了

服務(wù)器代碼：
Option Explicit
Private Sub Command1_Click()
    Dim BytDate() As Byte
    Dim FileName As String
    Dim lngFile As Long
    Dim i As Long
    FileName = "D:\Image\Oct2003.MDB "              '取得文件名及路徑
    lngFile = FileLen(FileName) \ 1024         '取得文件長度
    Me.ProgressBar1.Min = 0
    Me.ProgressBar1.Max = lngFile + 1
    ProgressBar1.Value = 0
    For i = 0 To lngFile
        ReDim myFile(1023) As Byte                 '初始化數(shù)組
        Open FileName For Binary As #1             '打開文件
        Get #1, i * 1024 + 1, myFile                        '將文件寫入數(shù)組
        Close #1                                   '關(guān)閉文件
        Winsock1.SendData myFile                   '發(fā)送
        DoEvents
        ProgressBar1.Value = ProgressBar1.Value + 1
    Next i
    If ProgressBar1.Value = ProgressBar1.Max Then MsgBox "OK"
End Sub

Private Sub Form_Load()
  Winsock1.Protocol = sckTCPProtocol
  Winsock1.LocalPort = 2001
  Winsock1.Listen
  FormCLI.Show
End Sub

Private Sub Winsock1_ConnectionRequest(ByVal requestID As Long)
  If Winsock1.State <> 0 Then Winsock1.Close
    Winsock1.Accept requestID
End Sub

客戶端：

Option Explicit
Private Sub Form_Load()
    With Winsock1
        .Protocol = sckTCPProtocol
        .RemoteHost = "192.168.0.69"
        .RemotePort = 2001
        .Connect
    End With
End Sub

Private Sub Winsock1_DataArrival(ByVal bytesTotal As Long)
    Static i As Long
    Dim myFile() As Byte
    Dim myLong As Double
    Dim myPath As String
    myPath = "d:\abc.MDB"
    ReDim myFile(bytesTotal - 1)       '此處也可以是(0 To bytesTotal-1)
    Winsock1.GetData myFile

    Open myPath For Binary As #1        '新建文件
    myLong = FileLen(myPath)
    Put #1, myLong + 1, myFile                  '將收到的數(shù)據(jù)寫入新文件中
    Close #1                                     '關(guān)閉
End Sub
