VB6 winsock.ocx bug?

 VB6 winsock.ocx bug?

I am a winsock newbie. I wrote a little tcp program by vb6 as followes:

private sub command1_click()
end sub

private sub scktcpServer.ConnectionRequest(Byval requestID as Long)
(nothing)--->that means no sockets accpet request
end sub

private sub command1_click()
end sub

I run them. But what's strange is that I alaways got a
scktcpClient.Connect() event though I didn't accept any request in Server

The book I read says that
"The Client socket will receive a connect event only after server scokets
accpet it"

What's wrong?

Anyone can give me some hints? or show me how to make client know if it is
accepted or rejected.

Thanks a lot,

 VB6 winsock.ocx bug?
Hi...I am here again. :)

After posting the last message, I found I could handle that by as followes:
I think the connect event occurs evertime the client finds server listen on
the port and ask to connect it.

The book I have may be wrong. :)

In server
Private Sub Winsock1_ConnectionRequest(ByVal requestID As Long)
    Dim ans As Long
    Winsock1.Accept requestID
    Label1.Caption = "Checking"
    ans = MsgBox("Yes or No?", vbYesNo)

    If ans = vbYes Then
        Winsock1.SendData "CONNECTED"
        Winsock1.SendData "REJECT"
    End If
End Sub

In Client
Private Sub Command1_Click()
    Winsock1.RemoteHost = ""
    Winsock1.RemotePort = 1007

    Loop Until Winsock1.State = sckConnected Or _
                   Winsock1.State = sckError
    If Winsock1.State = sckError Then
        MsgBox "Unable to connect to host."
    End If
End Sub

Private Sub Winsock1_DataArrival(ByVal bytesTotal As Long)
    Dim DataReceived As String

    Winsock1.GetData DataReceived, vbString
    Select Case DataReceived
        Case "REJECT"
            MsgBox "Reject your call"
            Winsock1.SendData "QUIT"
        Case "CONNECTED"
            MsgBox "Connecting succeeded"
    End Select
End Sub
