{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}

{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.
