I believe I solved it: It turns out that my
application was intercepting the WM_CLIENT_CLOSED
message mistakenly.
My application use TWSocketServer within a worker
thread, and this worker thread has a custom message
dispatcher so that it can process messages sent to
the thread without a hidden window. The problem was
that I forgot to check if the Msg.HWND property was 0
before calling the custom dispatcher.
Since I solved my own problem, and it has nothing
to do with TWSocket, this message is not Off Topic.

Its worse... I also noticed that
TWSocketClient.TriggerSessionClosed() is triggered by
the client, but the message posted is never received
by the server. This happens even then the client
drops the connection. So, for some reason, the
clients are never destroyed.
I'm sure that its something to do with my code,
but can anybody offer some suggestions as to what may
cause this behaviour?
Thanks,

>Hello:
I just started noticing this behaviour today, and
I seem to recall it working differently: When
handling the OnClientDataAvailable event, if I
determine that the client needs to be disconnected, I
call (Sender As TMyClient).Shutdown(1). The
connection is dropped fine, but the client object is
never freed until the server shuts down completely.
Here's a sample of my code:
Procedure TMyServer.ClientDataAvailable(Sender:
TObject; Error: Word);
Begin
With (Sender As TMyClient) Do Begin
If (SomethingBadHappened) Then Begin
SendLine('Error!');
Shutdown(1);
End;
End;
End;
I call Shutdown(1) so that the connection is dropped
gracefully and the error response is received by the
client. I don't recall changing this recently, so
I'm confused as to why it would have been destroying
the client before and not now (I may have changed
some of the default properties, though I don't recall
anything pertinent to this issue). Perhaps there's
an even better way?
Thanks for the help,
-dZ.
