Hi mmilan,

unit Unit1;

interface

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

type
  TForm1 = class(TForm)
    Button1: TButton;
    Memo1: TMemo;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.DFM}

procedure TForm1.Button1Click(Sender: TObject);
var i :integer;
begin
 for i:= 1 to 10 do begin
  memo1.lines.Add('this is line '+IntToStr(i));
 end;
end;

??? It did not work?

Open a new application :

put a button on your form
put a memo on your form

replace the unit code with this code I gave you

assign the clickevent of the button to buttonclick

here is another example:

just open a new application and replace unit code by this one :

unit Unit1;

interface

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

type
  TForm1 = class(TForm)
    procedure FormCreate(Sender: TObject);
    procedure FormDestroy(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
    memo : TMemo;
  end;

var
  Form1: TForm1;

implementation

{$R *.DFM}

procedure TForm1.FormCreate(Sender: TObject);
var i : integer;
begin
 memo := TMemo.Create(Form1);
 memo.Parent := Form1;
 for i := 1 to 10 do begin
  memo.lines.add('this is line '+IntToStr(i));
 end;
end;

procedure TForm1.FormDestroy(Sender: TObject);
begin
 memo.free;
end;

end.

Hi mmilan,

I just answer it again.

unit Unit1;

interface

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

type
  TForm1 = class(TForm)
    Button1: TButton;
    Memo1: TMemo;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.DFM}

procedure TForm1.Button1Click(Sender: TObject);
var i :integer;
begin
 for i:= 1 to 10 do begin
  memo1.lines.Add('this is line '+IntToStr(i));
 end;
end;

end.

Regards, Zif.
