Hi Arno, I went back over everything you provided for me and I finally got it! I have it working now.

Re: [twsocket] Using the FTP Client
Maybe "background loop" is the wrong term. I have a timer generating an event every 50mS. This routine processes the data from the USB and FTP. Well, this is slightly better but still use CPU for nothing most of the time. The master idea is to have all thread sleeping almost all time and waken up only when something has to be processed. Waking a thread up every 50 mS and then checking for some condition which is probably false most of the time is a waste of CPU and introduce a delay of 50 mS in every action, even if the system is doing nothing at the wake up time. Consider using windows events (or mutex or semaphore). It's quite easy once you've got the idea. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be - Original Message - From: "Graham Powell" To: "'ICS support mailing'" Sent: Friday, January 28, 2011 1:10 PM Subject: Re: [twsocket] Using the FTP Client Maybe "background loop" is the wrong term.

Reading that rings the bell in my head ! If you are using polling, then this is bad design. Use two separate threads to handle USB and to handle FTP. Each thread should work purely asynchronous (as ICS does) or work blocked on a read or write (for the USB). Never use a polling loop. The USB is read by a high priority thread and stored in a buffer. The background loop monitors the USB buffer and the buffered streams from the FTP and processes accordingly. OK, but what is the "background loop" ?

Or use a thread and create an event.
