timer

问题 I have created one timer application in javascript. Firstly it takes the current UTC date to init timer with some reference. here's the code on_timer: function(e) { var self = this; if ($(e.target).hasClass("pt_timer_start")) { var current_date = this.get_current_UTCDate(); this.project_timesheet_db.set_current_timer_activity({date: current_date}); this.start_interval(); this.initialize_timer(); this.$el.find(".pt_timer_start,.pt_timer_stop").toggleClass("o_hidden"); Now, Once timer is

问题 How do i convert an integer to LARGE_INTEGER? For example, when I want to trigger a timer immediately: LARGE_INTEGER zero; zero.QuadPart = 0; KeSetTimer(pTimer, zero, pDpc); Is there any way to convert 0 to LARGE_INTEGER? So I could do this instead: KeSetTimer(pTimer, (SomeType)0, pDpc); I have tried: KeSetTimer(pTimer, (LARGE_INTEGER )0, pDpc); But it doesn't work. I have Googled, but couldn't find any help. 回答1: LARGE_INTEGER is a struct . It is not possible to cast a value to a struct type

问题 I used alarm manager to do a work after a certain minute. But i need to find the remaining time whenever I open that activity.How to do that? Intent myIntent = new Intent(Activity1.this, Activity2.class); pendingIntent = PendingIntent.getService(Timeractivity.this, 0, myIntent, 0); int time = Integer.parseInt(time_et.getText().toString()); AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); Calendar calendar = Calendar.getInstance(); calendar.setTimeInMillis(System

问题 I'm trying to reproduce a simple timer with RxSwift. I have a pause/play button only that works for pause and resume. gameTimer = Observable<NSInteger>.interval(1, scheduler: MainScheduler.instance) .subscribeNext({ sec -> Void in print("\(sec) s") }).addDisposableTo(disposeBag!) pauseResumeButton.rx_tap .map{ !self.isRunning.value } .startWith(true) .bindTo( isRunning ) .addDisposableTo(disposeBag!) isRunning is an Variable< Bool > obviously. I can stop the timer settings disposeBag = nil

问题 I am try to create a timer app which have multiple countdown timer for different task. Issue, i am facing is that, if i start one timer, and press back button, timer stops. So i want, that timer to run till either it is being paused or timer ends and alerts the user or app is destroyed.Help me how can i do this using Flutter? Also i using sql-lite to store all timers. 回答1: Ah, background tasks! Dart (the language Flutter uses) is single-threaded . What does single-threaded mean? Single

问题 I'm currently stuck on a problem with a timer. I've got a function that is started by a timer every x seconds. Now the function execution can sometimes take longer under different conditions. So I want the timer to rerun only when it has completed the function. How can I achieve this? 回答1: Right before it exits, your function could trigger an event. The event will be caught by another function, which will start the timer. 回答2: My advice would be to avoid using a Timer class for this. The

问题 My goal is simple, like a lot of applications, I want to make my cursor invisible after a certain time of inactivity of my user. My solution doesn't seem really optimized , here's the algorithm : void Start { Timer t = new Timer(5000);//Create a timer of 5 second t.start(); } void Update { if(MouseMoved){ t.reset(); } timeLeft = t.deltaTime; if ( timeLeft == 5000 ) { Cursor.visible = false; } } I really don't like to check at every frame if the mouse is moved, I'd prefer that my mouse moved

问题 In the following code, a Timer is declared inside a function, where it also subscribes to the Elapsed event: void StartTimer() { System.Timers.Timer timer = new System.Timers.Timer(1000); timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed); timer.AutoReset = false; timer.Start(); } Once the function completes, the reference to the Timer is lost (I presume). Does the Elapsed event get unregistered automatically as the object is destroyed, or if not, can the event be
