从一个 LNK (快捷方式)取得该快捷方式的指向 EXE(可执行档)?

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, 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
uses activex,comobj,shlobj;
{$R *.dfm}

function ResolveLink(const ALinkFile: String): String;
var
  link: IShellLink;
  storage: IPersistFile;
  filedata: TWin32FindData;
  buf: Array[0..MAX_PATH] of Char;
  widepath: WideString;
begin
  OleCheck(CoCreateInstance(CLSID_ShellLink, nil, CLSCTX_INPROC_SERVER, IShellLink, link));
  OleCheck(link.QueryInterface(IPersistFile, storage));
  widepath := ALinkFile;
  Result := 'unable to resolve link';
  If Succeeded(storage.Load(@widepath[1], STGM_READ)) Then
    If Succeeded(link.Resolve(GetActiveWindow, SLR_NOUPDATE)) Then
      If Succeeded(link.GetPath(buf, sizeof(buf), filedata, SLGP_UNCPRIORITY)) Then
        Result := buf;
  storage := nil;
  link:= nil;
end;

// 用法:
procedure TForm1.Button1Click(Sender: TObject);
begin
  ShowMessage(ResolveLink('C:\delphi 7.lnk'));
end;

end.
