建立快捷方式的函数: CreateShortcut - 非常实用、特别方便

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

  Result := False;

  if not FileExists(Exe) then Exit;

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



  IObj := CreateComObject(CLSID_ShellLink);

  ILnk := IObj as IShellLink;

  ILnk.SetPath(PChar(Exe));

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



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

  if ID > -1 then

  begin

    SHGetSpecialFolderLocation(0, ID, PIDL);

    SHGetPathFromIDList(PIDL, InFolder);

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

  end else

  begin

    Dir := ExcludeTrailingPathDelimiter(Dir);

    if not DirectoryExists(Dir) then Exit;

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

  end;



  IPFile := IObj as IPersistFile;

  if IPFile.Save(PWideChar(LinkFileName), False) = 0 then Result := True;

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.
