Description:
Title: Adding shortcuts to the Win95/WinNT40 desktop or start menu

This sample project demonstrates an easy way to add shortcuts to
your Windows 95 or Windows NT 4.0 desktop or start menu.

1. Launch Delphi.

2. In a new project, drop a TButton on the form (make sure it's
   called Button1). Then double click on Button1. Now you can go
   ahead and directly replace the code for Unit1 with the code for
   Unit1 below.

The program will set up a shortcut either (see the code) on the
desktop or on the start menu. The shortcut will be called FooBar
and it will open up your AUTOEXEC.BAT in NOTEPAD when executed.

It will read the value of the "Desktop" and "Start Menu" strings
from the registry key named (under HKEY_CURRENT_USER):

 Software\MicroSoft\Windows\CurrentVersion\Explorer\Shell Folders

--------------
The Unit1 unit
--------------

unit Unit1;

interface

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

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

var
  Form1: TForm1;

implementation

{$R *.DFM}

uses
  ShlObj, ActiveX, ComObj, Registry;

procedure TForm1.Button1Click(Sender: TObject);
var
  MyObject  : IUnknown;
  MySLink   : IShellLink;
  MyPFile   : IPersistFile;
  FileName  : String;
  Directory : String;
  WFileName : WideString;
  MyReg     : TRegIniFile;
begin
  MyObject := CreateComObject(CLSID_ShellLink);
  MySLink := MyObject as IShellLink;
  MyPFile := MyObject as IPersistFile;
  FileName := 'NOTEPAD.EXE';
  with MySLink do begin
    SetArguments('C:\AUTOEXEC.BAT');
    SetPath(PChar(FileName));
    SetWorkingDirectory(PChar(ExtractFilePath(FileName)));
  end;
  MyReg := TRegIniFile.Create(
    'Software\MicroSoft\Windows\CurrentVersion\Explorer');

// Use the next line of code to put the shortcut on your desktop
  Directory := MyReg.ReadString('Shell Folders','Desktop','');

// Use the next three lines to put the shortcut on your start menu
//  Directory := MyReg.ReadString('Shell Folders','Start Menu','')+
//      '\Whoa!';
//  CreateDir(Directory);

  WFileName := Directory+'\FooBar.lnk';
  MyPFile.Save(PWChar(WFileName),False);
  MyReg.Free;
end;

end.
