delphi中建立快捷方式的函数

unit Unit1;

interface

uses

Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,

Dialogs, StdCtrls;

type

TForm1 =class(TForm)

   Button1: TButton;

   Button2: TButton;

   Button3: TButton;

   Button4: TButton;

  procedure Button1Click(Sender: TObject);

  procedure Button2Click(Sender: TObject);

  procedure Button3Click(Sender: TObject);

  procedure Button4Click(Sender: TObject);

end;

var

Form1: TForm1;

implementation

{$R *.dfm}

uses

ShlObj, ActiveX, ComObj;{该函数使用的单元}

{函数说明:}

{第一个参数是要建立快捷方式的文件, 这是必须的; 其他都是可选参数}

{第二个参数是快捷方式名称, 缺省使用参数一的文件名}

{第三个参数是指定目的文件夹, 缺省目的是桌面; 如果有第四个参数, 该参数将被忽略}

{第四个参数是用常数的方式指定目的文件夹; 该系列常数定义在 ShlObj 单元, CSIDL_ 打头}

function CreateShortcut(Exe:string; Lnk:string =''; Dir:string = ''; ID:Integer = -1):Boolean;

var

IObj: IUnknown;

ILnk: IShellLink;

IPFile: IPersistFile;

PIDL: PItemIDList;

InFolder:array[0..MAX_PATH]of Char;

LinkFileName: WideString;

begin

ifnot FileExists(Exe)then Exit;

if Lnk =''then Lnk := ChangeFileExt(ExtractFileName(Exe),'');

IObj := CreateComObject(CLSID_ShellLink);

ILnk := IObjas IShellLink;

ILnk.SetPath(PChar(Exe));

ILnk.SetWorkingDirectory(PChar(ExtractFilePath(Exe)));

if (Dir ='')and (ID = -1)then ID := CSIDL_DESKTOP;

if ID > -1then

  begin

     SHGetSpecialFolderLocation(0, ID, PIDL);

     SHGetPathFromIDList(PIDL, InFolder);

     LinkFileName := Format('%s\%s.lnk', [InFolder, Lnk]);

  end

  end;

end;

{CreateShortcut 函数结束}

{测试 1: 把当前程序在桌面上建立快捷方式}

procedure TForm1.Button1Click(Sender: TObject);

begin

CreateShortcut(Application.ExeName);

end;

{测试 2: 在桌面上建立快捷方式, 同时指定快捷方式名称}

procedure TForm1.Button2Click(Sender: TObject);

begin

CreateShortcut(Application.ExeName,'NewLinkName');

end;

{测试 3: 在 C:\ 下建立快捷方式}

procedure TForm1.Button3Click(Sender: TObject);

begin

CreateShortcut(Application.ExeName,'','C:\');

end;

{测试 3: 在开始菜单的程序文件夹下建立快捷方式}

procedure TForm1.Button4Click(Sender: TObject);

begin

CreateShortcut(Application.ExeName,'','', CSIDL_PROGRAMS);

end;

end.
