Imagine a server with many concurrent connections but that only allows one
connection at a time to submit a request, access/manipulate data and then
send the results back to all other connections. In other words all
requests
(regardless of which connection it's coming from) must be serialized.

Sorry, I will remember next time...
The OnSessionClosed is never fired in this case (when the host disconnects), I

Hello Frédéric,
It seems to work, but it would be interesting to understand why I
don't get any info at the socket side when I power off the printer for
example...
This is because the printer does just poweroff. Disconnecting a TCP
session means that the disconnecting side will send a packet
You can remove the offending line and /ADD/ the following two lines at the
beginning of InternalOpenLogFile, just after InternalCloseLogFile:
if (FLogFileOption = lfoOverwrite) and FileExists(FLogFileName) then
DeleteFile(FLogFileName);
This should solve the problem and yet preserve
Would a TTimer OnTimer event in the main application thread mess
with the message pump?
The timer is driven by the message pump and is quite safe, if not
essential in most ICS applications to handle timeouts, lockouts, etc.

Hello Brian,
I'm eager now to try ICS.
Good :)
Out of curiosity, is the behavior of the D5 TServerSocket (in non-blocking
mode) the same as ICS? I've used the D5 component in the past and have run
into some problems that led me to believe it was not serializing properly.
Dont know, but I

And what is the problem ? Use the TWSocket handle.
Thanks, I must have had a blackout yesterday evening.

But zero is fine for the handle. I use this code in a DLL to close
a database on inactivity.
Thanks Angus, sometimes, especially after a 16 hours day it may

Does anyone already used ICS in C# in async mode ?

There is currently no ICS for C# version. But there is a Delphi.NET version.
Normally that version should be usable directly from C# provided you build
an assembly using Delphi.NET (If you have BDS2006, you can do both
Delphi.NET and C# at the same time).
Note that if you really need a pure C#
