要点:1.代码备注的超级详细，如下:unit Unit1;interfaceuses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls, ComCtrls;type TForm1 = class(TForm) lv1: TListView; Button1: TButton; Button2: TButton; Button3: TButt
ImageList1属性如下设置：DrawingStyle: dsTransparentColorDepth: cd32Bit

处理事情： 数据处理过程中，速度很慢，无法准确定位分析是DB问题还是客户端处理问题，所以增加计时统计日志； Delphi计时首次使用，查阅资料，予以记录：var BgPoint, EdPoind: int64; OffSet: int64;begin BgPoint := GetTickCount; //>> 逻辑处理语句。。。。。。 EdPoind := GetTickCount; OffSet := EdPoind - BgPoint; //耗时(ms)end;//>>
