Hi
I still have the same problem and i dont know why. My last test was:
1.SocketServer
2.Onclientconnect Show connection
3.OdataAvalilable : read the info send by other program, create a thread
when the information is recieved and create a new thread with a sleep(500)
instruction and the postmessage to make a send call from the main thread
4.OnClientDisconnect Show the list with all the clients.
I did this in TcpSrv (adding the thread etc ) demo and into a service. The
demo works fine and no blank ip port connections appeared but the service
did not work and in some moment did not receive more connections. I still
have 10038 errors in BgExcep. I already check buffers and all code to avoid
lose of the handle.
I have the demo programs, maybe i can upload or send if somebody want to
test.
If is possible i want to talk by phone with somebody into the ICS team, or
by msn or other media and of course we can agreed a fee for the advices. I
am in a difficult position because my dead line was this weekend. My mail is
[EMAIL PROTECTED] ( timezone Colombia )
Thank you for the help

If you use V6 there may be collisions with window messages in the beginning
of range WM_USER posted to the same _thread where TWSocketServer created
it's
hidden window, are you using V6? Do you use PostThreadMessage?
Do you create the TWSocketServer instance in OnCreate of
TService? Only if you create it in TService.OnStart it'd run in the
service thread.

Do you access the TWSocketClients from the worker threads directly, or
do you post a messsage with the worker thread result to the thread where
the TWSocketServer and its clients are running in?
If it's not the message-collision-problem of V6, it may have
to do with improper use of ICS in a multi-threaded env.,
beside the possible reasons Wilfried and Francois already mentioned.
