ASync Lookup for ServerSocket in non-blocking ?

Greetings all,

Well, I have found the Internet Chat example from Borland quite helpful. I 
split it into a separate server and client and made the server simply 
receive a file name from the client and return it's date/time, (and removed 
all UI from the server.) Works fine.

Now,
I am trying to convert the server into a SERVICE. I can build the service 
and get it to install and start/stop etc.

But,
I get an error like so upon running the service in non-blocking mode 
(blocking mode gives no error and no results) :

ERROR MSG:
" Windows socket error: The requested name is valid and was found in the 
database, but it does not have the correct associated data being resolved 
for (11004), on API 'ASync Lookup' "

Apparently, this means I need to set the ASyncStyles property of 
TCustomWinSocket to include the events I want to handle.

But I am not sure how to do this - the help defines it like so:

<Code begins>

enum TAsyncStyle { asRead, asWrite, asOOB, asAccept, asConnect, asClose };
typedef Set<TAsyncStyle, asRead, asClose>  TAsyncStyles;
__property TAsyncStyles ASyncStyles = {read=FAsyncStyles, 
write=SetAsyncStyles, nodefault};

<Code ends>

How do I set these ASyncStyles please?
I tried an assignment, I tried using SetASyncStyles, I included sysset.h
Can not get it to work.

Also - on which event should I set these?

Regards,

Quentin
