When we debug, optimize our code, want to know the actual execution time of a piece of code, or we suspect that a piece of code, or a few pieces of code execution is relatively slow,Need to get specific execution time for a particular piece of code. There is a very useful class stopwatch.The Stopwatch class is under the System.Diagnostics namespace. Basic tools that you can use to analyze. NET code blocks.For example:System.Diagnostics.Stopwatch timer
after startup, a timer is automatically activated and this is triggered when the timer time is reached. close Public partial class form1: Form { Public form1 () {}
Private void form1_load (Object sender, eventargs E){My Timer. interval = 10000; // set the time to 10 secondsMy Timer. Tick + = new eventhandler (my timer _ tick );My Timer. Start (); // This timer is automatically started when the form is loaded}// Timer timing eventVoid my timer _ tick (Object sender, eventargs E){This. Close ();
This article mainly introduces the simple design of the stopwatch timer in javascript. the stopwatch will contain two buttons and a text box for displaying the time. the minimum unit is 0.01 seconds when you click the Start button, at this time, click the button again to stop Timing. the text box shows the elapsed time. if you need it, refer to the example in this article to describe the implementation code
Once started, a Timer is automatically activated and this. Close is triggered when the Timer time is reached.Public partial class Form1: Form{Timer my Timer = new Timer ();Public Form1 (){InitializeComponent ();}
Private void Form1_Load (object sender, EventArgs e){My Timer. Interval = 10000; // set the time to 10 secondsMy Timer. Tick + = new EventHandler (my timer _ Tick );My Timer. Start (); // This timer is automatically started when the form is loaded}// Timer timing eventVoid my timer _ T
First, start or continue to measure the elapsed time of an interval, then stop, last reset time, output.usingSystem;usingSystem.Collections.Generic;usingSystem.Diagnostics;usingSystem.Linq;usingsystem.web;usingSystem.Web.UI;usingSystem.Web.UI.WebControls; Public Partial classtestperformance:system.web.ui.page{protected voidPage_Load (Objectsender, EventArgs e) { /*Var Performance Test*/Stopwatch STW=NewStopwatch (); ListLong> intlist =NewlistLo
The stopwatch counting function is implemented using timers and external interrupts. The number 8th button represents the start/end of the timer, the C key represents a reset of 0, and is limited to 15 seconds for demonstration purposes.There is a detailed comment in the code:#include Single-chip microcomputer: C language Implementation stopwatch count (start, end, reset button)
We continue the journey of QT, this time is still a small thing, it is a stopwatch, this stopwatch is mainly logical operation, in fact, there is not much content, that is, learning about the use of qtime and Qtimer, we look at what the UI looks like
Here is very simple, we first analyze the control, the top is a qlcdnumber to display the number of seconds, the middle of four buttons to control, the follow

The timer of 51 single-chip microcomputer is 0 in the way of 1 timing. The result is displayed with four digital tubes, which are 10 seconds, 1 second, milliseconds, and 10 milliseconds. Therefore, the maximum time is 1 minute, accurate to 0.01 s. At the same time, add three independent buttons to control the reset, pause, and start functions of the stopwatch.
According to the modular idea, first write the functions and predefined values to a header f

The seventh bullet in Android development: simple clock (stopwatch)
This article undertakes, Android Development Fifth play: simple clock (alarm clock) and Android Development Sixth play: simple clock (timer), this part is about the stopwatch.
Layout
You can also create a new class (StopWatchView), extend it from LinearLayout, and use it for layout.
Stopwatch class: Http://msdn.microsoft.com/zh-cn/library/system.diagnostics.stopwatch (v=vs.100). aspxCommon Properties and methods:Start (): Starts or continues to measure the elapsed time of an interval.Stop (): Stops measuring the elapsed time of an interval.Elapsedmilliseconds: Gets the total elapsed time (in milliseconds) measured by the current instance.Example:usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;usingSy
The frame of the stopwatch is metallic, and it is troublesome to make the texture part. At the same time, the production methods for different parts are different. The ring can be made with a layer style, and the button must be made with a metal gradient.

Stopwatch provides an API for recording time slice, which is provided in the lang package under Apache. In addition, you can refer to a similar tool class in the Spring framework to achieve slightly different effects, but both provide a time record function, see another article: http://blog.csdn.net/lxzo123/article/details/6608162

I am not busy with my recent work. In my spare time, I learned how to use object-C to experience an invincible IOS framework. I want to write a small application trainer and pick a simple question for myself: imitating and implementing the stopwatch program in the IOS system application clock is the application:
Main functions:
1. Timing by the start/stop key
2. Reset and count with the reset/lap key
Considerations:
1. Time Representation (there are
