If you don’t have access to the main thread, you can throw the exception on another, non-timer thread: catch (Exception exception) { ThreadPool.QueueUserWorkItem( _ => { throw new Exception(“Exception on timer.”, exception); }); }
According to the Timer documentation, in Java 1.5 onwards, you should prefer the ScheduledThreadPoolExecutor instead. (You may like to create this executor using Executors.newSingleThreadScheduledExecutor() for ease of use; it creates something much like a Timer.) The cool thing is, when you schedule a task (by calling schedule()), it returns a ScheduledFuture object. You can use … Read more
Go’s defer makes this trivial. In Go 1.x, define the following functions: func trace(s string) (string, time.Time) { log.Println(“START:”, s) return s, time.Now() } func un(s string, startTime time.Time) { endTime := time.Now() log.Println(” END:”, s, “ElapsedTime in seconds:”, endTime.Sub(startTime)) } After that, you get Squeaky Clean one line elapsed time log messages: func someFunction() … Read more
When the workbook first opens, execute this code: alertTime = Now + TimeValue(“00:02:00”) Application.OnTime alertTime, “EventMacro” Then just have a macro in the workbook called “EventMacro” that will repeat it. Public Sub EventMacro() ‘… Execute your actions here’ alertTime = Now + TimeValue(“00:02:00”) Application.OnTime alertTime, “EventMacro” End Sub
Timer expects a sequence (normally, a list or tuple) of arguments and a mapping (normally, a dict) of keyword arguments, so pass a list instead: import threading def hello(arg): print(arg) t = threading.Timer(2, hello, [“bb”]) t.start() while 1: pass Since “bb” is an iterable, the Timer will iterate over it and use each element as … Read more
Unfortunately, it seems that Go developers will not add such functionality in any foreseeable future, so we have to cope… There are two common ways to use tickers: for loop Given something like this: ticker := time.NewTicker(period) defer ticker.Stop() for <- ticker.C { … } Use: ticker := time.NewTicker(period) defer ticker.Stop() for ; true; <- … Read more
DispatcherTimer is the regular timer. It fires its Tick event on the UI thread, you can do anything you want with the UI. System.Timers.Timer is an asynchronous timer, its Elapsed event runs on a thread pool thread. You have to be very careful in your event handler, you are not allowed to touch any UI … Read more
Calendar today = Calendar.getInstance(); today.set(Calendar.HOUR_OF_DAY, 2); today.set(Calendar.MINUTE, 0); today.set(Calendar.SECOND, 0); // every night at 2am you run your task Timer timer = new Timer(); timer.schedule(new YourTask(), today.getTime(), TimeUnit.MILLISECONDS.convert(1, TimeUnit.DAYS)); // period: 1 day
Make sure you’re running your script in Bash, not /bin/sh. For example: #!/usr/bin/env bash sleep 0.1 In other words, try to specify the shell explicitly. Then run either by: ./foo.sh or bash foo.sh. In case, sleep is an alias or a function, try replacing sleep with \sleep.
new java.util.Timer().schedule( new java.util.TimerTask() { @Override public void run() { // your code here } }, 5000 ); EDIT: javadoc says: After the last live reference to a Timer object goes away and all outstanding tasks have completed execution, the timer’s task execution thread terminates gracefully (and becomes subject to garbage collection). However, this can … Read more
