问题 This question already has answers here : How to print one character at a time on one line? (3 answers) Closed last year . Okay, so I'm making a small programme for fun and I'd like to create a refresh button that allows the user to control how regularly the data is collected and shown. I decided to use the time.sleep(x) x being what the raw_input was. But it doesn't seem to be working as it should. It pauses the full script then does everything. eg: import time print "This now" time.sleep(x)

问题 In this web tutorial on threading in C#, Joseph Albahari writes: "Don't go sleeping in pooled threads!" Why should you not do this? How badly can it affect performance? (It's not that I want to do it; I'm just curious.) 回答1: Thread is a heavy-weight object. Creating a new thread requires lots of resources, such as assigning 1 MB for a managed stack, creating managed thread object, kernel stack, kernel thread object, user thread environment block. This all takes time and memory. Therefore you

问题 Can I use the msleep() function to sleep for a specified amount of time in kernel space? If so, which header files do I need to include? #include <linux/time.h> doesn't seem to be the right one. Is there perhaps a better function for this purpose? 回答1: I needed to include <linux/delay.h> to use msleep in kernel space. 回答2: Linux kernel documentation The Linux kernel documentation under Documentation/timers/timers-howto.txt has a good rundown of the main methods: Inserting Delays -------------

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 6 years ago . So I a label here (""). When the button (button1) is clicked, the label text turns into "Test". After 2 seconds, the text is set back into "". I made this work with a timer (which has an interval of 2000):

问题 The bug that annoys me is the same than this ticket. Basically, if you change the OS clock to a date in the past, all the thread that were sleeping at the time of the change won't wake up. The application I am developping is meant to be running 24/24, and we would like to be able to change the OS date without stopping it (for example, to switch from summer time to winter time). What happens for the moment is that when we change the date to the past, then some parts of the application just

问题 I spent a good long while looking for info on the differences between time.h::sleep() and pthread.h::pthread_yield() but was unable to find any solid reference material and so I am posting this question. What is the difference between time.h::sleep() and pthread.h::pthread_yield()? Update: The reason I ask is because I was using sleep() to sleep() each individual thread... and my application started having issues when there was 8 threads vs 4 threads. When I went online to see if sleep() only

问题 I have a userform which runs a script every 100ms. The script handles images on the userform and is used to animate them, while the form continues to receive user input (mouse clicks and key presses). This continues until the userform is closed. While Application.OnTime seems to work best, it only operates consistently on time values of 1 second or more. When I use something like Sub StartTimer() Application.OnTime now + (TimeValue("00:00:01") / 10), "Timer" End Sub Private Sub Timer()

问题 I am trying to create a sleep/delay procedure in 16bit MASM Assembly x86 that will, say, print a character on the screen every 500ms. From the research I have done, it seems that there are three methods to achieve this - I would like to use the one that uses CPU clock ticks. Please note I am running Windows XP through VMWare Fusion on Mac OS X Snow Leopard - I am not sure if that affects anything. Could someone please point me in the right direction, or provide a working piece of code I can

问题 first of all, I'm a beginner to android world so please apologize me if it is stupid question.. I'm trying to do following: Enable Mobile Data Wait for 10 seconds a. check if Mobile got IP address (data connected sucessfully) b. if Not connected,Disable Data c. Go to step 1 And these steps 1 to 3 are getting executed in For loop for User Given number of retries. Now my problem is: I'm stuck at step No. 2. I'm unable to make waitfor(int seconds) function. I tried using Runnable PostDelayed

问题 Both Thread.Sleep(timeout) and resetEvent.Wait(timeout) cause execution to pause for at least timeout milliseconds, so is there a difference between them? I know that Thread.Sleep causes the thread to give up the remainder of its time slice, thus possibly resulting in a sleep that lasts far longer than asked for. Does the Wait(timeout) method of a ManualResetEvent object have the same problem? Edit : I'm aware that a ManualResetEvent's main point is to be signaled from another thread - right
