    In VB6? You'd have to post some of your code for us to even begin to help.

    Also, your question isn't clear

    Good afternoon
    Yes my friend dglienna small multithread in vb 6.
    Here the ThreadListen and Workthread code to saw u how work with thread.
    code
    Public Function ThreadListen(ByVal Param As Long) As Long
    ThreadInit.InitThread
    Dim ClientID As Long
    Dim sAddr As sockaddr_in
    Dim sAddrLen As Long
    Dim IP As String
    TID = GetCurrentThreadId
    Lthread = TID
    listen hListenSck, 10
    Do While True
    sAddrLen = 16
    nRet = accept(hListenSck, sAddr, sAddrLen)
    If nRet <> SOCKET_ERROR Then
    ClientCount = ClientCount + 1
    SockStoreList.Add nRet
    Frmain.thlabel.Caption = ClientCount
    Add_ListData nRet, "127.0.0.1"
    End If

    ClientStore(ClientCount).sock_ID = nRet
    Thread.SetThreadFunc AddressOf WorkthreadTest, 0
    'Through the "thread Param" to pass parameters
    Thread.StartThread ClientCount

    Loop
    End Function
    --Workthread-------
    Public Function WorkthreadTest(ByVal Param As Long) As Long
    ThreadInit.InitThread
    Dim DBuff As String
    Dim ReadBuff As String
    Dim sRec As Long
    TID = GetCurrentThreadId
    Add_DataClientStore Param, nRet, TID
    ThreadList.Add TID
    WriteLog "Client Connected : Socket ID " & nRet & " On Thread ID:" & TID

    Do While True
    DBuff = Space(4096)
    sRec = recv(ClientStore(Param).sock_ID, ByVal DBuff, Len(DBuff), 0)
    If sRec <> 0 And sRec <> SOCKET_ERROR Then
    ReadBuff = ReadBuff & Left(DBuff, sRec)
    WriteData ReadBuff & " " & "Test Hello hello"

    WriteData "Data Received.:" & ReadBuff & " Socket ID..." & ClientStore(Param).sock_ID

    End If
    Loop
    End Function
    Code

    When Click on command(Listen)on FormMain Star a Thread (ThreadListen)to listen for Connections .
    When a client arrive just pass the SocketID to a New Thread(Workthread)
    In this thread run a loop to receive data .
    Until here make many testings and can say able to run 10 Clients(10 threads)
    If the Main form have a second Form(data)how can run this form and communicate with Workthread ?
    Or Just receive on workthread and the Sending on Data form ..
    thanks for the time

    Pretty complicated in VB6. I'd switch to VB.Net, where it should be a little simpler to test.

    Re: Multithreading Socket

    I can't tell much about what you are doing from the code posted but I can tell you that I have written a working server in VB6 that handles up to 25 connections without using threading and it works very well.
    Always use [code][/code] tags when posting code.
