hello,
thank for quick and useful response.
i'll try to upgrade to V7 now because i'm still getting error (catched by
Server.OnBgException event), I'm getting AccessViolation or
InvalidOperation exceptions.
These errors occurs after disconnecting client by server (i'm using
timer - in same way as you adviced me). I have tried to add C.Free call
but I have thought it was nonse (you have confirmed it me).
One question for sure:
When I call Client.Close the Client will be freed automatically
(destructor of Client will be called)?
thank you again
have a nice day

hello,
I have server application based on TWSocketServer, clients are derived
from TWSocketClient class.
I need disconnect inactive clients. I'm not sure how to disconnect
client, I'm using this:
procedure DisconnectMyClient(i: Integer);
var
C: TTcpSrvClient;
{TTcpSrvClient = class(TWSocketClient)}
begin
C := Server.Client[I] as TTcpSrvClient;
C.Close;
That works, though "Server.Client[I].Close" would be enough.
If want to close clients while iterating over the client list
make sure you iterate from high index down to zero like:
for I := Server.ClientCount -1 downto 0 do
Server.Client[I].Close;
A more brutal method to enforce client close was
Server.Disconnect().
C.Free; {Is this correct? sometimes it will throw access violation
here....} end;
That's wrong, don't do that. Client objects are freed and
removed from the internal client list when they are closed
or disconnected automatically by the server.
I'm using ICS v6.
You should update to ICSv7.
I did notice that Server.OnClientDisconnect event is not triggered
when client is not closed correctly (e.g. client is plugged of
ethernet).
That's the expected behaviour.
Is there any possibility to detect and/or disconnect these
clients automatically?
Implement an idle timeout at the server side. Let the client send
some keep alive data in intervals so the server knows a client is
still there.
