如何从一个LNK取得该快捷方式的指向EXE？

这段时间,老被一个问题困扰,动态创建Button控件,然后从*.LNK档案取得该*.EXE档案,进而得到该EXE档案的图标,最后就是把取得的图标一一对应显示在动态创建的Button上面;
刚开始的时候,天真的认为,系统会自动的从*.LNK档案取得EXE路径的,但是现实告诉我,这样不行!只好从*.LNK档案上动手脚了,如下:

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;

//引用方法很简单啊!ResolveLink()返回一个 String , 正是我需要的 Type :-);

end.
