如果读写注册表,以及如何显示系统信息?如操作系统名称及版本,还有可能物理内存,就像Windows的关于对话框显示的一样

GetSystemInfo 系统信息
GetWindowsDirectory
GetEnvironmentStrings
GlobalMemoryStatus

2、用TRegIniFile,TRegistry
3、可以用TStrings.Text写入
下面是Delphi的例子：
unit reginid;

interface

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

type
TRegIniForm = class(TForm)
GroupBox1: TGroupBox;
Label1: TLabel;
CheckBox_Write: TCheckBox;
RadioGroup_Write: TRadioGroup;
Edit_Write: TEdit;
GroupBox2: TGroupBox;
Label3: TLabel;
CheckBox_Read: TCheckBox;
RadioGroup_Read: TRadioGroup;

Edit_Read: TEdit;
Memo_Read: TMemo;
Button_Write: TButton;
Button_Read: TButton;
procedure FormCreate(Sender: TObject);
procedure FormDestroy(Sender: TObject);
procedure Button_WriteClick(Sender: TObject);
procedure Button_ReadClick(Sender: TObject);
procedure CheckBox_ReadClick(Sender: TObject);
procedure RadioGroup_ReadClick(Sender: TObject);
private
{ Private declarations }
procedure Read_Registry;

procedure Write_Registry;
public
{ Public declarations }
FIniFile: TRegIniFile;
end;

var
RegIniForm: TRegIniForm;

implementation

{$R *.DFM}

const
SECTION = 'Sample';

procedure TRegIniForm.FormCreate(Sender: TObject);
begin
FIniFile := TRegIniFile.Create('Sample Registry');
end;

procedure TRegIniForm.FormDestroy(Sender: TObject);
var
Cleanup: TRegistry;

key: string;
begin
key := FIniFile.FileName;
FIniFile.Free;

// make sure we don't leave junk in the registry behind.
Cleanup := TRegistry.Create;
try
Cleanup.DeleteKey(key);
finally
Cleanup.Free;
end;
end;

procedure TRegIniForm.Write_Registry;
begin
FIniFile.WriteBool(SECTION, 'BooleanTest', CheckBox_Write.Checked);
FIniFile.WriteInteger(SECTION, 'IntegerTest', RadioGroup_Write.ItemIndex);

FIniFile.WriteString(SECTION, 'StringTest', Edit_Write.Text);

if not Button_Read.Enabled then Button_Read.Enabled := True;
end;

procedure TRegIniForm.Read_Registry;
begin
CheckBox_Read.Checked := FIniFile.ReadBool(SECTION, 'BooleanTest', False);
RadioGroup_Read.ItemIndex := FIniFile.ReadInteger(SECTION, 'IntegerTest', 0);
Edit_Read.Text := FIniFile.ReadString(SECTION, 'StringTest', '');

Memo_Read.Lines.Clear;

FIniFile.ReadSectionValues(SECTION, Memo_Read.Lines);

Button_Read.Enabled := False;
end;

procedure TRegIniForm.Button_WriteClick(Sender: TObject);
begin
Write_Registry;
end;

procedure TRegIniForm.Button_ReadClick(Sender: TObject);
begin
Read_Registry;
end;


procedure TRegIniForm.CheckBox_ReadClick(Sender: TObject);
begin
Read_Registry;
end;

procedure TRegIniForm.RadioGroup_ReadClick(Sender: TObject);

begin
Read_Registry;
end;

end.
