Hello,

thanks a lot.

Unfortunately I'm not used at all to Windows programming. I tried to use
a library thats wrap missing API for Windows 2000, but with no luck (gpt
some obscure DLL issues):

Maybe the ConnectEx() API replacement used by this library could be a
solution ? (see code attached to this mail)

Regards,
