sleep

问题 hi guys, This is the extension of the question Auto redirecting to another pages at regular intervels. from there i got an idea to use sleep(value). I've developed a code here. <!------- Here goes script> <script type="text/javascript"> //Input the IDs of the IFRAMES you wish to dynamically resize to match its content height: //Separate each ID with a comma. Examples: ["myframe1", "myframe2"] or ["myframe"] or [] for none: var iframeids=["myframe"] //Should script hide iframe from browsers

问题 In Command Prompt, I'd throw the following into an iterated loop: choice /c:abcdefghijklmnopqrstuvwxyz1234567890 /n /t:1 /d:0 sleep 1 In Unix, I'd use: read -t 5 $input . Does anyone know a way to do it in Powershell? Right now, I just wait it out (last line below). I've set my script to switch between the TV and PC for my wife. I print a before and after for my wife and I'd like to bypass it for myself. Here is my current script for context: $file_location = "C:\Users\krmar_000\Documents

问题 I need to delay my program's execution for a specified number of milliseconds, but also want the user to be able to escape the wait when a key is pressed. If no key is pressed the program should wait for the specified number of milliseconds. I have been using Thread.Sleep to halt the program (which in the context of my program I think is ok as the UI is set to minimise during the execution of the main method). I have thought about doing something like this: while(GetAsyncKeyState(System

问题 I need to write a helper method which I can use in various places in the app to essentially make it 'sleep' for N milliseconds.It looks like Handler.postAtTime may be one way to do it, but I'd like any code snippets if available. 回答1: Are you looking for something like this? try { //Put the thread to sleep for the desired amount of time (milliseconds) Thread.currentThread().sleep(1000); } catch(InterruptedException ie){ } This will put the thread you are calling it from to sleep for the

问题 I'm trying to figure out how to pause a loop in php so it executes once every 5 minutes for example while($row=$stmt->fetch(PDO::FETCH_ASSOC)){ //send email to a member // pause for a minute then continue the loop } simple example for($x=0;$x<=4;$x++){ echo $x."<br>"; sleep(5); // the loop will be delayed for 25 seconds then it'll print 5 lines at once } 回答1: This script works as you expect. Every iteration of the loop is being delayed 5 seconds. However, what you are seeing is the output

问题 Good day to all. I have a little problem: How do I close the sleeping connections to a database? When I issue a query the query is executed then the connection remains on sleep mode for 2-3 seconds. The problem is that I generate queries faster than they are closed. Is there a way to force a connection to close before entering in the sleep mode? Or any workaround. Thank you for help. Note: The connections are not permanent, they close, but just to slow... Note 2 - for the mysql_close(): The

问题 I have an app that uses GPS for regular updates. It used to be the case that when the device was put to sleep (screen turned off, screen timeout etc), the location updates kept on coming through. This was on an HTC Desire running 2.2. I need that behaviour for various reasons. However, now being tested on an HTC Desire S running 4.0.4, and what seems to happen is that updates continue (1/sec) for about 5 seconds after entering sleep mode, but then stop. However, exactly the same code running

问题 i have tried to implement the data transfer between usb and cpu in this project. The data transfer is being shown as a small rectangle moving from one component of the computer to another. In the code below, the GlutPostRedisplay does not work. Also, can someone tell me if sleep() used is correct because the functions called in display do not work in sync. casing() is never executed. After fisrtscreen(), it directly jumps to opened() and operate() does not work. what is the error with this

问题 I have a bash script: #!/bin/sh for ((i=0; i<=10; i++)); do ssh "w$i" 'uptime;ps -elf|grep httpd|wc -l;free -m;mpstat' done & pid=$! sleep 3 kill -9 $pid I want to kill the ssh within the for loop , if it does not complete within 3 seconds. But my observations are, that the process is not killed and that the loop takes more than 3 seconds to kill. Can you please help me to correct my script so my script can kill the for loop process after 3 seconds? 来源： https://stackoverflow.com/questions

问题 Because I'm executing a time critical task every second, I compared several methods to find the best way to ensure that my task is really executed in fixed time steps. After calculating the standard derivation of the error for all methods it seems like using the method scheduledExecutorService.scheduleAtFixedRate() leads to the best results, but I don't have a clue why it is so. Does anybody know how that method internally works? How does it for example in comparison to a simple sleep()
