在前面例子的基础上, 探讨新问题.假如我们想让几个线程(例子中是 3 个)依次执行, 我们可以使用临界区、信号、互斥等手段;但下面第一个例子什么同步工具都没用, 也达到了目的; 方法是: 让前一个线程在结束前顺便启动下一个线程.第二个例子使用了互斥对象配合 WaitForS...
多线程编程(18) - 再从一个小例子出发
万一| 万一的 Delphi 博客 |21:17:00
前面的例子都是让若干线程做同样的事情, 下面这个例子中的三个线程将分别在三个画板上随机画不同颜色的椭圆.接下来的很多事情我想要基于这个例子来做.本例效果图:代码文件:unit Unit1; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics...

万一| 万一的 Delphi 博客 |16:03:00
//例子中的三个变量让 absolute 都给弄到一块了, 这有时会很方便; 但我总也想不到用, 还是不熟. procedure TForm1.FormCreate(Sender: TObject); var num: Int64; pt: TPoint absolute num; arr: array[0..1] of Integer absolute pt; begin pt.X := 111; ...

多线程编程(16) - 多线程同步之 WaitableTimer (等待定时器对象)[续二]
万一| 万一的 Delphi 博客 |23:43:00
喝酒醉了一天, 重装系统一天, 两天没上博客了; 继续学习...想过没有? WaitableTimer 是在 "定时等待", 前面例子中的 WaitForSingleObject 等待函数 "也在等待", 这就 "双重等待" 了, 这不好, 太浪费资源.其实作为同步工具, 前面的几种方法(事件、信号、临界区)基本够...
