Sorry, I will remember next time...
The OnSessionClosed is never fired in this case (when the host disconnects), I
don't know why. I think it's because thi

Hi
I have just downloaded ICS version 5 and am trying to install this into Delphi
2. I have followed the instructions in the readme file but get an error during
the install in relation to the icslogger component saying "cannot assign to a
read-only property" for the line
FLogFile.Size := 0;

But zero is fine for the handle. I use this code in a DLL to close
a database on inactivity.

procedure TimerProc (Wnd: HWnd; Msg: Integer; Id: Integer;
This is less of a socket question and more of an implementation question.
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

And what is the problem ? Use the TWSocket handle.

Hello Arno,
I have to check, but I think there is also be an option to create a
timer without have a window. then it post a message to a message
queue.
another option is to create a custom timer using a thread.

I guess it is lost, since I guess that checksum checks are done on the

I know UDP is unreliable and packets may be lost, but are they
checksum'd again corruption? And if the checksum fails, is the packet
then lost?
The real question is whether my UDP protocol needs to add it's own
checksum.
Also, how reliable is having multiple applications listening for the

On my site you find a serial comport component (TCiaComPort). It has a
custom Timer on board that does not create a window, but can use an
existing window. It does not have to include
You probably are using blocking socket. This is bad since the message pump
doesn't work anymore so ICS component can't have his events processed.
You'd better use TWSocket instead of the API.

You may use Windows API to avoid TTimer and ExtCtrls.

Use ReceiveFrom to know from where the packet is comming and throw it away
if you don't like the sender.

Hello,
I UDP sendto a request datagram to the server,
when OnDataAvailable triggers I call ReceiveFrom()
in order to read the response.
But I think OnDataAvailable is being triggered when
any datagram addressed to that port arrives, even
datagrams not sent by the destination server. How
to handle

Writing/using message loops is not specific to Delphi but to Window
Hello Patrick,
No using TSyncPop3Cli is discouraged.
I cannot check at moment. But the component has a data socket, FSocket
probably or similar. You can use the messageloop from this one if you
sete on this TWSocket MultiThread to true.

When connection will break then OnSessionClosed will fire. There you
start a timer and after some seconds o
