timer

问题 I have tried multiple ways to have a single persistent timer update the ui in multiple activities, and nothing seems to work. I have tried an AsyncTask, a Handler, and a CountDownTimer. The code below does not execute the first Log.i statement.... Is there a better way to start the timer (which must be called from another class) in Main (which is the only persistent class)? public static void MainLawTimer() { MainActivity.lawTimer = new CountDownTimer(MainActivity.timeLeft, 1000) { public

问题 I'm trying to implement Java EE websockets with a Glassfish server, and I've got the basics down already. As for my current project, I want to implement server "ticks" like in a game, that update the server every few milliseconds so that all sessions connected to the server see the same thing. However, I don't know where to start to make this work with Glassfish. I know that I create a server from scratch and implement a timer method, but I'd rather save myself some work here if possible.

问题 I am developing a Windows Service application, in .NET, which executes many functions (it is a WCF service host), and one of the targets is running scheduled tasks. I chose to create a System.Threading.Timer for every operation, with a dueTime set to the next execution and no period to avoid reentrancy. Every time the operation ends, it changes the dueTime to match the next scheduled execution. Most of the operations are scheduled to run every minute, not all toghether but delayed by some

问题 Here is my code: window.onload = runThis; function runThis() { const txtMin = document.getElementsByClassName("min"); const txtSec = document.getElementsByClassName("sec"); function go() { setInterval(countDown, 1000); } function countDown() { timeNow = timeNow - 1; timeSec = timeNow % 60; //remainder as seconds timeMin = Math.round((timeNow/60) - (timeSec/60)); //minutes txtMin[0].innerText = (timeMin > 0 ? (timeMin >= 10 ? `${timeMin}:` : `0${timeMin}:`) : "00:"); txtSec[0].innerText =

问题 in Posting Before : I want to get response time on a simple math value if "button calculate" press, get sum value a and value b in textbox and also show how long to proceed that math calculation (response time) in textbox. BUT why my result always grow up / always up like in picture how to make result stable and less volatile ? the result when i click calculate button on a continuous picture coding button calculate Private Sub Button4_Click(sender As System.Object, e As System.EventArgs)

问题 I'm having a hard hard time with Timer function from threading. Basically, when my program starts, I want to log stats every x second. So I thought I could do it with the Timer function (launch function every 5 second). For now, I did : from threading import Timer def startLogger(): while True: t = Timer(5, function) t.start() def function(): print("hey") But it launch error, so I think it's not the good way to do it. RuntimeError: can't start new thread If someone can give me a clue, it

问题 I am creating a web template for sale, but I can't make timer count down, I don't how to make it. I need timer count down (when a date is added, it should be decreased), also it should not restart on refresh time or shut down time. Please help me to do this code... I will use it in my template. 回答1: If you are not working with a database, then you can use HTML5 localstorage. Store a variable on the users local machine if they have already visited. When the page loads, do a check of local

问题 I was trying POSIX timers togheter with POSIX signals handling. When I try to excecute the code you can find downhere, I get: Errore timer_settime: Invalid argument On GAPIL book, that is based upon Advanced Linux Programming and Unix network programming, I read that this can happen when inside new_value.value you specified a negative time value or a number of nanoseconds higher than 999999999. But I think that parameters I have used are okay... #include <string.h> #include <stdio.h> #include

问题 I have an Android app that needs to display images and videos in a loop, it has no problem with playing the videos, but when it gets to the images the screen goes blank and nothing happens. the program is still running just not displaying. I'm using SurfaceView.setBackground() to draw the image because swapping between an ImageView and the SurfaceView that the videos are played on has caused problems before. I was having a similar issue when displaying the videos and I solved it by removing
