Just reading? Use the regedit.exe program (c:\windows\regedit.exe)

I mean I want to make a program that can run as an Install Shield, so while installing a software we added registry entry to Windows 95 Operating System. Thank you for your answers.

Look at the TRegistry-object if you are using D2/3 or the TRegIni-object in D1.

Try this:

unit Unit1;

interface

uses
  Windows, Forms, Dialogs, Registry, StdCtrls, Controls, Classes;

type
  TForm1 = class(TForm)
    Edit1: TEdit;
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.DFM}

Function GetExecuteable(Const Extension: String): String;
// Extension = '.XXX'
var
  Reg: TRegistry;
  FileType: String;
Begin
  Result:= '';
  Try
    Reg:= TRegistry.Create;
    With Reg do
    Begin
      Reg.Rootkey:= HKEY_CLASSES_ROOT;
      If OpenKey(Extension,False) then // We don't want to create key
      If ValueExists('') then // '' means default value
      Begin
        FileType:= ReadString('');
        CloseKey;
        if OpenKey(FileType+'\Shell\Open\Command',False) then
        if ValueExists('') then Result:= ReadString('');
      End;
    End;
  Finally
    Reg.Free;
  End;
End;

procedure TForm1.Button1Click(Sender: TObject);
begin
  ShowMessage('Executable: '+GetExecuteable(Edit1.Text));
end;
