findlistitem.pas

上传个考勤系统,希望别人也能用.该代码只能算初级的东东,软件代码复用性不高,重复代码比较多.唯一感觉有点取鉴的可能就是端口和dll的连接,还有线程的使用,本想改一改,但是手头没有考勤机了,对应考勤机是

unit FindListItem;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TdlgFindListItem = class(TForm)
    Label1: TLabel;
    Label2: TLabel;
    Label3: TLabel;
    edContent: TEdit;
    cbFindColumn: TComboBox;
    cbMatching: TComboBox;
    btnOk: TButton;
    Button2: TButton;
    procedure edContentKeyPress(Sender: TObject; var Key: Char);
    procedure edContentChange(Sender: TObject);
    procedure FormCreate(Sender: TObject);
    procedure FormDestroy(Sender: TObject);
    procedure FormShow(Sender: TObject);
    procedure FormCloseQuery(Sender: TObject; var CanClose: Boolean);
  private
    { Private declarations }
  public
    { Public declarations }
