have a look at the "clock" functionality. a clock is basically a scheduled callback. if you want it to happen repeatedly (like metro), you have to reschedule the clock within the callback. apart from that: why don't you just use [metro]? thus nobody has to learn how to start/stop the polling and to set the polling interval; instead they can just use an object which they already know (and if not will find that they should already know :-)) fgmnasdr IOhannes
