No, TWSocket does not use any threads. Windows does internally, but that is transparent to a Delphi application. All events are called in the context of the thread in which the component is created, usually the main application. Generally, it's not a good idea to do anything complex in the events, but trigger your own event (with PostMessage) for further processing. If you are doing a lot of different connections, it's important to wait for session connect and disconnect events to be called, before starting a new connection, since TCP/IP has long timeouts for lost or failed connections. Call Abort to break a connection, but still wait for the event. ICS does allow you to make simultaneous connections to multiple different remote devices, without needing threads, several hundred if necessary, memory permitting.
