Hi everyone.

I am having troubles with indys tcpclient and tcpserver.

I can't see why it can give so many problems just to disconnect a thread. It gives errors and everything.

Just wan't to be able to disconnect a thread and free it correctly.

i have tried this in hope to disconnect client:
    AThread.Terminate;
    AThread.Free;
and also AThread.Connection.Disconnect;
but everything seems to give errors in some way, and nothing is been free correctly.

Hope someone knows how to do a simple disconnect without getting errors.

Thanks

what error do you get ?
generally you only need to Disconnect the connection
the thread will be reused by the ThreadManager (hope you have one)
if there is no thread manager then the thread will be freed when the client disconnects

Goal is : Terminate the TIDThread with its "TerminateAndWaitFor" method only.

Assume you have a Thread derived from TIdThread doing your connection, with a TIdTCPClient like MyClient inside.

1.) Override TIdThreads BeforeRun, Run and AfterRun.
2.) Connect somewhere in TMyIdThread.BeforeRun or TMyIdThread.Run
3.) Doing your work in the Run-Loop, terminate this loop if MyClient.Connected is false or Stopped is TRUE.
4.) Call Stop to disconnect manually, e.g. on errors
5.) Disconnect in AfterRun only if still connected:
  "if MyClient.Connected then MyClient.Disconnect;"
 
So, when terminating your TIdThread from the outside by calling "TerminateAndWaitFor", connection will be disconnected. On the other hand a 'reset by peer' will disconnect and terminate your thread also.
