personcard.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 PersonCard;

interface

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

type
  TdlgPersonCard = class(TForm)
    edInputCard: TEdit;
    Label1: TLabel;
    btnOk: TButton;
    btnCancel: TButton;
    procedure edInputCardKeyPress(Sender: TObject; var Key: Char);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  dlgPersonCard: TdlgPersonCard;

implementation

{$R *.dfm}

procedure TdlgPersonCard.edInputCardKeyPress(Sender: TObject; var Key: Char);
begin
    if not (key in [#13,'0'..'9']) then Key:=#0;
    if key = #13 then  btnOk.Click;
end;

end.
