多线程在VB.NET下的实现

Realization of multithread using VB.NET

为了在 VB.NET 中处理并发问题和多任务管理的问题,使用多线程编程技术这一程序设计最为广泛应用的技术是最方便的解决方法,应用需要多个任务时可以使用多线程技术。在键盘输入数据的同时另一个线程在计算井传输数据,其它的线程可以同时完成屏幕的更新显示、或从端口读入数据等。研究了在 VB.NET 中线程的创建、运行和终止的方法,及如何确定和更改线程的状态和线程的同步问题。通过对 VB.NET 编译环境中线程对象的分析,深入剖析了多线程技术在 VB.NET 编译环境中的实现过程,说明了 VB.NET 中基于多线程技术的程序开发过程。

The programming with multiplethreads is one of the most widely used technologies,it is also a good solution to synchronic problems and multiple tasks.We should consider using more than one thread if our application needs to manage multiple activities,such as simultaneous keyboard input and calculations.One thread can process keyboard input while a second thread performs data transformation calculations.A third thread can update the display screen based on data from the keyboard thread.At the same time,other threads can access disk files,or get data from a communications port.Base on analyses of thread object and its implementation under VB.NET environment,this paper describes the mechanism and the method of multithreading under VB.NET.Then we expound the multithreading applications design.
