. Net2.0 also provides the stopwatch class, which can accurately measure the time.
Speed test:
The performance and testability of software is a complex topic. To ensure that an application meets your expectations, you need to consider its performance and testability during the development cycle. This is crucial in the design phase, and a poor design will almost certainly lead to a poor user experience. However, only a good design does not ensure that

Javascript stopwatch Timer
Instance code:
When the timer is set to run interval, 100 is set at the beginning. In fact, it is incorrect because 1 second = 1000 milliseconds. We need to divide it into 60 numbers for display, therefore, we need to divide it by 60.

Stopwatch and stopwatch
Stopwatch:Stopwatch timer, used to record the running time of the program, usually used to test the code execution efficiency in time. (Reference: System. Diagnostics .)Stopwatch sw = new Stopwatch (); // instantiate an object.
Sw. Start ():Enable the timer.
Sw. Stop ():Disable the timer.

Ideas:
1. Add the upper part of the stopwatch, for example, 00: 00: 00. 00, which respectively indicates the time, minute, second, and millisecond. A total of seven labe are used for implementation.
2. Set the buttons to start, stop, and reset.
3.
(1) Create a new graphic element with the name "Candle". Into the editing scene for this component.
(2) "Candle" components are divided into three layers. Make the candle body layer first. Double-click Layer 1 on the timeline and rename layer 1 to "candle body". As shown in Figure 2-120.

Callatz conjecture:
For any natural number n, if it is an even number, cut it by half; if it is an odd number, cut (3n + 1) by half. In this way, we will continue to cut down and finally get n = 1 in a certain step. Karaz announced this conjecture at the world mathematician conference in 1950. It is said that at that time, the teachers

Usually, the market will not rise straight, nor fall vertically, but in two steps, step back. Before the current trend continues, the market will usually first have to make a certain degree of drawdown on the process of progress or decline that has been formed. In this kind of retracement level, the more commonly used is 50% retracement level, and the Fibonacci retracement level of 38% and 62%.The Fibonacci sequence refers to a sequence of 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233,377,61

Today is the last day of the May Day holiday. There is nothing to do with it. After quietly looking at the igoogle tool development document for half a day, after analyzing a few gadgets, it's actually not difficult.
