    This example does not work. WS_Connect cannot find entry point in dll
    A.M. | 2006-05-15 16:11:30
    Replace line
    nResult = ws_connect(hSocket, @cBuffer, Len(cBuffer))

    DECLARE INTEGER WSAConnect IN ws2_32;
        INTEGER s, STRING @sname, INTEGER namelen,;
        INTEGER lpCallerData, INTEGER lpCalleeData,;

    nResult = WSAConnect(hSocket, @cBuffer, Len(cBuffer), 0, 0, 0, 0)

    It may work better.
