Need Help Delphi 2010 CheckBox1 Stored value in memo

Hello Guys I'm new with Delphi which uses pascal language.
I'm trying to create simple application which loaded all values in sMemo.Text. All Strings were working fine except with Boolean values "CheckBox and radio Buttons"
here is the line I'm using
sMemo1.Lines.Add(sCheckBox1.Create );
it gives me an error
[DCC Error] Unit1.pas(44): E2035 Not enough actual parameters.

here is my whole code

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, sCheckBox, sRadioButton, sGroupBox, sButton, sEdit, sMemo,
  sLabel;

type
  TForm1 = class(TForm)
    sMemo1: TsMemo;
    sEdit1: TsEdit;
    sEdit2: TsEdit;
    sEdit3: TsEdit;
    sButton1: TsButton;
    sButton2: TsButton;
    sGroupBox1: TsGroupBox;
    sRadioButton1: TsRadioButton;
    sRadioButton2: TsRadioButton;
    sCheckBox1: TsCheckBox;
    sMemo2: TsMemo;
    sLabel1: TsLabel;
    procedure sButton1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.sButton1Click(Sender: TObject);
begin
sMemo1.Clear;
sMemo1.Lines.Add(sEdit1.Text);
sMemo1.Lines.Add(sEdit2.Text);
sMemo1.Lines.Add(sEdit3.Text);
sMemo1.Lines.Add(sCheckBox1.Create);
end;
end.


Anyone here knows that. My main purpose with this app is to load all configuration into memo instead of an ini file wich is easy to read an modified with someone. I want to load all config i memo and encrypt  content in memo and save it as a file format

Commented:
for the checkbox and radiobutton you'll have to convert a boolean to a string


why exactly do you want to use "a visual component" (= memo) for something you don't want users to see ?
it is a common misconcept
use a TStrings instead

procedure TForm1.sButton1Click(Sender: TObject);
  function BoolToStr(b: Boolean): string;
  begin
    Result := '0';
    if b then Result := '1';
  end;
var List: TStrings;
begin
  List := TStringList.Create;
  try
    List.Add(sEdit1.Text);
    List.Add(sEdit2.Text);
    List.Add(sEdit3.Text);
    List.Add(BoolToStr(sCheckBox1.Checked));
    List.SaveToFile('yourtextfile.txt');
    // to see the actual text in a memo: 
    // smemo1.Lines.Assign(List);
  finally
    List.Free;
  end;
end.

i thought you were going to come back ...
there will be a problem when you add components.


procedure TForm1.sButton1Click(Sender: TObject);
begin
  SaveSettings;
end;

procedure TForm1.SaveSettings;
  function BoolToStr(b: Boolean): string;
  begin
    Result := '0';
    if b then Result := '1';
  end;
var List: TStrings;
begin
  List := TStringList.Create;
  try
    List.Values['Edit1'] := sEdit1.Text;
    List.Values['Edit2'] := sEdit2.Text;
    List.Values['Edit3'] := sEdit3.Text;
    List.Values['Check1'] := BoolToStr(sCheckBox1.Checked);
    List.SaveToFile('yourtextfile.txt');
    // to see the actual text in a memo: 
    // smemo1.Lines.Assign(List);
  finally
    List.Free;
  end;
end.

procedure TForm1.LoadSettings;
function StrToBool(s: string): boolean;
  begin
    Result := False;
    if s = '1' then Result := True;
  end;
var List: TStrings;
begin
  List := TStringList.Create;
  try
    List.LoadFromFile('yourtextfile.txt');
    sEdit1.Text := List.Values['Edit1'];
    sEdit2.Text := List.Values['Edit2'];
    sEdit3.Text := List.Values['Edit3'];
    sCheckBox1.Checked := StrToBool(List.Values['Check1']);
  finally
    List.Free;
  end;
end;

Hit Ctrl-Shift-C for code completion after replacing the Button1Click procedure with above code

I already Solve it using this code..

procedure TForm1.sButton2Click(Sender: TObject);
var
  value :  String ;
begin
value := sMemo1.Lines[0];
sCheckBox1.Checked := StrToBool(value);
end;

end.
