Hello,
I'm writing a application in D2006 and build a communication dll for it.
The communications dll encapsulates different communication methods (for USB,
ethernet...).
Ethernet communication is done via ICS TWSocket, the version included on the
partner cd.
The DLL has a data module which ha

Hello,
sorry, pressed the wrong button.
I had changed the code now so that the socket is created within the context of
the thread
(veryfied by GetCurrentThreadID) at start of execute and closing is initiated
at the end of
execute (same threadID). In the communication DLL (not the one which co
Hello Markus,
Why not .free the socket thru a message sent in .OnClose event ? This
is a better way than doing a sleep(x) that tends to defeat
asynchronous ICS model, you' better thing in term of events.
Also you could not free you TWSocket but re-use later as you maintain
a TObjectL
Hello,
Think that ICS is fully asynchronous and event driven, it's a
different approach comparing to Indy or other Socket components and
also comparaing to RS232 programming where synchronous mode is usual.
With ICS (server or client mode) you can make or receive thousand of
connexi

Hello,
to the socket hanging on close.
There are different threads involved.
The communication dll has one thread which only polls messages.
That one shouldn't be the problem.
The dll using that communication dll has one thread per socket
(max. at most 10). Freing the socket is requested by this
Hello Markus,
Why do you use one thread per socket ? TSWocket is event driven so you
can connect to 500 servers if you want within same thread.
For polling messages, if you .mulithread:=true then the TWSocket will
create its own message queue.

And the socket has been _created in method execute as well?
How do you achieve that client sockets run in the

The message was meant because many people think they need a thread per
communication TWSocket channel. So I assume you have your own reason to
have a thread.
What you can do is Create and destroy TWS

Hi Marcus,
I've been following your problem and I believe that the problem you have
is because you are trying to use a dll with only a little
multi-threading experience. One of the reasons people avoid threads is
that it requires a lot of reading, development time, experience and when
something go

Use GetCurrentThreadID to find out the thread context of the code.
Check this where the TWSocket is created and where you Destroy it. Check
this also in some of the TWSocket e
