问题 I want to put a php daemon to sleep (with System_Daemon::iterate()) so it runs max 20 times randomly spread over an hour. maybe a min distance would be smart so it doesn't run 20 times in the first half hour and 0 times in the second half. i'm kinda stuck here and don't know how to start with this one, any help is very apreciated! 回答1: You may use cron jobs, to set the script to run ever so often. http://net.tutsplus.com/tutorials/php/managing-cron-jobs-with-php-2/ ...

问题 i am populating the timespec structure. The intention is, user will always enter values in seconds (can also be 0.01 secs), so we are converting the seconds to nanoseconds using: lt_leak_start = atoll(getenv("LT_LEAK_START")) * sec_to_nsec; where variable static long sec_to_nsec = 1000000000; and then using it as an argument to settime: timer_settime(timerid,0,&its,NULL) . But on doing it an error occurs: settimer failed: Invalid argument Please help me. Thanks in advance. enter code here

问题 I am developing an app for android that measures some network parameters every hour. I already have the code to do the measurements, so I only need some help on how to make it do it periodically. What should I use? Timers, Alarms or something else? Do you have any easy example on how it works? Thanks for your help! 回答1: The only good answer is to use AlarmManager . Having a service that sits for an hour waiting for the hour to pass is ridiculous. 回答2: Using a service (so that you're not tied

问题 Currently in my application, I have a RelayCommand which calls an action which starts a Timer . I have a separate command which the calls the Dispose() method to get rid of/release the timer. This all sits in the ViewModel counterpart of the project. Using the MVVM pattern, how would I dispose of this Timer upon closing the window, as well as carrying out the regular/default operation of closing the window? I am also using the MVVM-Light toolkit, if this is of any help. An example of my

问题 I actually try to add a Splash Screen to my WPF application. It is quite easy: SplashScreen s = new SplashScreen("/Images/Agrar.png"); s.Show(true); My problem is, that I want the Splash Screen to show about 10sec, but my Application doesn´t need so long to load. So I thought about the Timer class and tried a bit, but I don´t know how to combine it with a Splash Screen. Is there a better solution? How does it work with Timer? Because I didn´t find a option to say, what should happen while the

问题 Currently I have the following code creating my timer: <script type="text/javascript"> var interval; var minutes = 8; var seconds = 10; function countdown(element) { interval = setInterval(function() { var el = document.getElementById(element); if(seconds == 0) { if(minutes == 0) { alert(el.innerHTML = "countdown's over!"); clearInterval(interval); return; } else { minutes--; seconds = 60; } } if(minutes > 0) { var minute_text = minutes + (minutes > 1 ? ' minutes' : ' minute'); } else { var

问题 I have a CountDownTimer which updates a TextView, but when I press the back button it stops. CountDownTimer timer = new CountDownTimer(600000, 100) { public void onTick(long millisUntilFinished) { calendar.setTimeInMillis(millisUntilFinished); cron.setText(sf.format(calendar.getTime())); } public void onFinish() { } }; How can I keep it running when I press the back button and the activity gets destroyed? PS: I also start a GPS service when the timer starts, Is there a way to put the

问题 what is the maximum interval for a timer to work in C#? is it the maximum value of int 32? can i change it to int 64? If i change, that is ONE big IF, will a timer still be working? 回答1: System.Timers.Timer.Interval: The time, in milliseconds, between Elapsed events. The value must be greater than zero, and less than or equal to Int32.MaxValue . The default is 100 milliseconds. You cannot assign an Int64 to an Int32 (that is larger than Int32.MaxValue ) Of interest: Comparing the Timer
