how do you detect that a process is running "asynchronously"?
OK, how can i detect that some process is running without a timer? Like...if the printer is printing or the camera is turned on? I obviously can't use ifelse in the form constructor since it will  run only at...runtime. I know some classes...such as for printing classes will be called only once a printing operation is complete...so good to have such event handling. But in the general case - is there some general way when you can detect everything without using a timer on every second? 10x!
