Thanks.
Another questions,

Does Winsock freezes (like URLDownloadToFile or Inet control) when you try to connect to a http site but there is no internet connection present ?

if you dont create some code in the WS_Error event, then yes it will create the effect that your socket has frozen even though it actually has returned an error, so have something like this

Private Sub Winsock182_Error(ByVal Number As Integer, Description As String, ByVal Scode As Long, ByVal Source As String, ByVal HelpFile As String, ByVal HelpContext As Long, CancelDisplay As Boolean)
    Winsock182.Close
    MsgBox "Error (" & Number & "): " & Description, vbCritical, "Socket Error"
End Sub

this will give a msgbox saying the err num+description such as

---------------------------
Socket Error
---------------------------
Error (11001): Authoritative answer: Host not found
---------------------------
OK
---------------------------

best winsock site ever is www.winsockvb.com that is literally all you need, tuts for everything from basic chat to multi threaded downloads

...just a little heads up for using winsock:

never ever do this as many do:

Private Sub Winsock1_Close()
    MsgBox "Connection closed"
End Sub

you will be trapped forever until the end of time in a looping msgbox!

always use Close method before displaying the msgbox like

Private Sub Winsock1_Close()
    Winsock182.Close
    MsgBox "Connection closed"
End Sub

BTW the close event fires when the remote host terminates the connection
