得分界面与代码设计实现
unit Defen;

interface

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

type
  TDeFenForm = class(TForm)
    Label1: TLabel;
    Label2: TLabel;
    renming: TListBox;
    defen: TListBox;
    Button1: TButton;
    procedure FormCreate(Sender: TObject);
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  DeFenForm: TDeFenForm;

implementation
 uses kaishi;
{$R *.DFM}

procedure TDeFenForm.FormCreate(Sender: TObject);
begin
renming.Items.LoadFromFile(kaishiform.AppPath+'\rm.sav');
defen.Items.LoadFromFile(kaishiform.AppPath+'\df.sav');
end;

procedure TDeFenForm.Button1Click(Sender: TObject);
begin
renming.Items.Clear;
defen.Items.Clear;
renming.Items.SaveToFile(kaishiform.AppPath+'\rm.sav');
defen.Items.SaveToFile(kaishiform.AppPath+'\df.sav');
end;

end.

 

 

关于界面与代码设计实现

代码设计:
unit GuanYu;

interface

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

type
  TGuanYuForm = class(TForm)
    Label1: TLabel;
    Label3: TLabel;
    Label2: TLabel;
    Label4: TLabel;
    Label5: TLabel;
    Label8: TLabel;
    Label9: TLabel;
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  GuanYuForm: TGuanYuForm;
