Your design is correct altough you'd better use TWSocketServer instead of
reinventing the wheel. You can set MaxClients to one to support only one
client at a time.
Calling send from another thread is OK because it is protected by a critical
section.
Note that the prefered design is to have al
Hello,
I'm currently writing a COM-Server which also uses TWSocket for some TCP

Thanks for the clarification.
Let me explain my scenario.
This application is an IP Surveillance software, where the server software
is responsible for recording video from IP Cameras, so, to get the video it
connects to the camera through the socket.

Hello Eric,
You need a message handler for the thread with a while(GetMessage(...)).

I´m writing a multi-threaded client application
I read the ICS code and there is written that to make a real multi-threaded

I´m doing this, but, how do I stop this thread?

I _think_ there is a freeware downloadable version. But there are also

That's what the online help let me think.
Conclusion:
In addition to the code I published, one need to use {$A8} directive (Or the
equivalent project option, which is set to 8 by default) for all classes
having their event hand

Isn't a field "properly aligned in memory" when switch {$A8} is set?

Hello,
AFAIK, this tool comes with VC++. Unfortunately I do not have that
installed.
Anyway, when you say "random message", I guess you mean some code is posting
with wrong message number. Hmmm, strange...

I don't know, and it also raises a second question:

This raise the following question : Is a field variable in a class aligned
in memory ? (OnMyEvent variable is just a field variable).

You have some part of your code post a random message.
I suggest you use Microsoft Spy++ tool to spy on your application messages.

I do not know of any such poster routine. What I do to reproduce the problem
is to press F5 on browser which means the connection is opened but then
aborted abruptly.

I think so since pointer are 32 bits and are accessed by only one memory
cycle. If you look at the Windows API InterlockedXYZ function, there is none
