VB记时器编程的讨论 在很多场合下编程（例如工业控制、游戏）中需要比较精确的记时器，本文讨论的是在VB下实现记时器的若干方法以及它们的精度控制问题。

在VB中最常用的是Timer控件，它的设置和使用都非常方便，理论上它的记时精度可以达到1ms(毫秒)。但是众所周知的，实际上Timer在记时间隔小于50ms之下是精度是十分差的。它只适用于对于精度要求不太高的场合。 -VB timer programming on many occasions to discuss programming (such as industrial control, games) need a more precise timer, this discussion is in the VB timer to achieve a number of methods and their precision control. The most commonly used in the VB Timer control is, it' s very easy to set up and use, in theory, its accuracy can be achieved when the mind 1ms (ms). But we all know, in fact, every time Timer is less than 50ms in the mind is under the precision is very poor. It applies only to not too high for the accuracy of the occasion.
