timer

问题 I'm writing a simple program, which checks if elapsed time is more than 1 seconds. I take start time with a clock_gettime(), then I call sleep(5), take new time and I check if the difference is bigger than 1; I sleep 5 seconds, then it should be greater than 5, but my program prints a strange result. this is the code: #include <stdio.h> #include <stdlib.h> #include <time.h> #include <unistd.h> int main() { struct timespec tv1,tv3,expected; struct timespec nano1; tv1.tv_nsec = 0; tv3.tv_nsec =

问题 See the Image below: Scenario I have a repeater control bearing Id " rpt1 " ,inside the ItemTemplate of which I have a span control whose Id is " abc ", which is currently displaying a number. I also have a ticker above the repeater in format dd-MM-yyyy hh:mm:ss (27-05-2013 11:24:36), made up of ASP:Timer and ASP:UpdatePanel .

问题 I need to display the elapsed time dynamically.

问题 How can one ensure that a task that is supposed to run for x amount of time on an android os be run for that x period without user manipulation of date and time? For example, if I want this timer to run for 24 hours solid and then advise the user that 24h has passed, even if the phone is off for an hour, the user then turns it back on and sets the system time forward 2 hours, this timer would still indicate when that solid 24 hour period had passed without the user manipulating the system

问题 This question already has answers here : How to set time limit on raw_input [duplicate] (6 answers) Closed 4 years ago . I have a small script that I have written to perform tasks every 5 minutes (this does not need to be exact), but as it is written currently the only way it can be cancelled is with Ctrl+Z (linux terminal) and there is no way of changing what set of tasks it performs without restarting the script. As a result, I'd like to change the script to be able to accept user input

问题 I creating an windows service which will from time to time check if a certain exists and if it does, then reads from it, sends data to a server and move a file to another folder. A file's size is about 1-3 Mb. I think I will use System.Threading.Timer here to check if a file exists. What do you think of it? And another question. If a file is being copied then my app must not read from it. It should wait until copying is done. Only after that it must read from it and does other activities. So

问题 I need to display elapsed time in my application form.

问题 I have datagridview whose datasource is datatable. I have two columns in datagridview: NAME, IN TIME After the datagridview is loaded, I want to add a new column called DURATION which is a timer column i.e. based on the IN TIME, DURATION column should display a stopwatch with the timespan interval of CURRENT TIME-IN TIME. How do I make the DURATION column stopwatch to continue the timer for every seconds like digital clock? 回答1: You can add a string column to DataTable and use it as duration
