timer

问题 I have created and installed a service a couple of times. Initially it was working fine, but after some changes in the service Code it start giving the error when I restart the service in Services.msc : Error 1053: the service did not respond to the start or control request in a timely fashion Code: public partial class AutoSMS : ServiceBase { public AutoSMS() { InitializeComponent(); eventLog1.Clear(); if (!System.Diagnostics.EventLog.SourceExists("MySource")) { System.Diagnostics.EventLog

问题 When I run my Virtual Machine with Gentoo as guest, I have found that there is considerable overhead coming from tick_periodic function. (This is the function which runs on every timer interrupt.) This function updates a global jiffy using write_seqlocks which leads to the overhead. Here's a grep of HZ and relevant stuff in my kernel config file. sharan013@sitmac4:~$ cat /boot/config | egrep 'HZ|TIME' # CONFIG_RCU_FAST_NO_HZ is not set CONFIG_NO_HZ=y # CONFIG_HZ_100 is not set # CONFIG_HZ_250

问题 Currently, I am working on a quiz game and in that, for each question, I wish to place a countdown timer. I got some plugins, but I wish if I could create it myself. What I am trying to create looks like the one in the image below.Can you please tell me how I can do it? Is there a way to assign a border to only up to a specified percentage of the perimeter, so that I could give a border, first in full, and then as each second advances, I can keep decreasing/increasing it so that I would get

问题 I use QTimer to send periodically 'Ping' packet to the server (MQTT client). But it timer is not absolutely accurate. After some time of working it has some delay and server broken connection. I try to use different Qt::TimerType, but it does not help. I need the most accurate timer. Do you have any ideas? Thank you! EDIT (Frederik solution) I have done something this: tthread.h class TThread : public QThread { Q_OBJECT void run(); public: explicit TThread(QObject *parent = 0); signals:

问题 I've created a game; in which one of the main components is a countdown timer- however this timer is delayed and I am not able to deduce why. This is how I have the timer set up: loops = 0 minute = 1 tens = 0 ones = 0 #Timer Calculation screen.blit(cloudSky, (0,0)) if go == True: loops = loops + 1 if (loops % 60)== 0: if ones == 0 and tens == 0 and minute != 0: tens = 6 ones = 0 minute = minute - 1 if ones == 0 and tens != 0: ones = 9 tens = tens - 1 elif ones != 0: ones = ones - 1 elif tens

I'm struggling with making button first click to start a timer, second click to stop the timer and etc. Can anybody help me? :) private void button7_Click(object sender, EventArgs e) { timer1.Start(); } 回答1: Use the Enabled property: if (timer1.Enabled) { timer1.Stop(); } else { timer1.Start(); }

问题 I'm doing a Java project where I have to make a GUI that contains multiple timers that countdown from a user input time. When I create only one timer, the program works fine, but when I try to include multiple timers, each timer will countdown faster based on how many timers there are. I think the problem is being caused by the ActionListener being called multiple times each time the swing timer calls for an action, but I do not know how to solve that problem. Here is my CountDownTimer class

问题 I am creating an online exam page for my project. I have a countdown timer, but it resets on page refresh. How can I make it not to reset? The timer is set by fetching time from db. I am using php mysql. Please help me. Here is my code. <?php $result=mysql_query("select * from test where testid='29'"); while($time=mysql_fetch_array($result)){ $dateFormat = "d F Y -- g:i a"; $targetDate = time() + ($time['duration']*60); $actualDate = time(); $secondsDiff = $targetDate - $actualDate;

问题 I'm using WebIM for chat support on a website. I would like to be able to setup a timer for when a client initiates a chat session, if an operator/tech does not respond within 'x' seconds I would like the page to redirect to another page where the client can leave a message. Sortof a 'please hold while we try to connect you' thing. That way if all the techs are too busy or helping other clients the client waiting can simply try back later or leave a message (as such when chat is offline). I

问题 I've started a course of c# and I cant get my timer to run. Its probably pretty simple and I've just missed something here. Basically I have a button to start and stop a traffic light sequence. I wanted an interval of 1 second. Heres what I've written. It doesn't work as intended when I press start. Thank you. } public int counter = 0; private void rbStart_CheckedChanged(object sender, EventArgs e) { counter++; if (counter == 1) { pbRed.Visible = true; pbAmber.Visible = false; pbGreen.Visible
