问题 I want to make a batch file that waits for a few minutes, then executes a command. How would I do this? Specifically, I want it to end another program in 3 minutes after opening the file. 回答1: Another method is to ping an invalid IP address for a certain amount of time: PING 1.1.1.1 -n 1 -w 60000 >NUL 60000 = milliseconds 回答2: Use timeout .

问题 I have a ton of update panels and such on my webform (which are created dynamically at runtime) I am wanting to put a locking timer or something similar in my form also. My problem is this. When someone is typing into a text box, and the timer happens they lose part of their text and the control loses focus. The reason this happens is because on post back some things are done and the screen is rebuilt and the current control panel is updated. The reason this happens is because the only things

问题 This code is supposed to produce the following effect: when .expander is moused over, it waits 400 milliseconds and then expands to 150% of its original size over the course of 270 milliseconds. If the mouse leaves .expander , the expansion is cancelled. <div class="expander"><%=image_tag("expander.jpg")%></div> <script type="text/javascript"> $(".expander").on('mouseenter', function () { $.data(this, 'timer', setTimeout(function () { $(this).stop(true, true).animate({width: "150%"}, 270,

问题 For the challenge and educational gain, i am currently trying to make a simple game in the console window . I use a very primitive "locked" framerate system as such: using System.Threading; // ... static private void Main(string[] args) { AutoResetEvent autoEvent = new AutoResetEvent(false); Timer timer = new Timer(Update); timer.Change(0, GameSpeed); autoEvent.WaitOne(); } So, a timer ticks every GameSpeed miliseconds, and calls the method Update() . The way that i have understood input in

问题 I have a background tick function that is structured as follows: System.Threading.Thread myTimerThread = new Thread(this.Tick); private void Tick(){ do{ //do stuff System.Threading.Sleep(1000L); }while(true) } However, there is also a System.Threading.Timer class that does this for me. What are the differences in using the built in Timer class present in System.Threading rather than creating my own background thread with a Tick function? 回答1: The Timer class would be very light weight and

问题 I am implementing a timer and need it to run every 50 ms or so and would like the resolution to be 1 ms or less. I started by reading these two articles: http://www.codeproject.com/Articles/1236/Timers-Tutorial http://www.virtualdub.org/blog/pivot/entry.php?id=272 Oddly enough they seem to contradict one another. One says queue timers are good for high resolution, the other posts results from a Windows 7 system showing resolution around 15ms (not good enough for my application). So I ran a
