大哥！紧急求救！如何在桌面上生成快捷方式！！在线等待！ (300分)

在delphi中写代码，让我的文件（比如：c:/y.exe）在桌面上自动生成快捷方式！！
还有，如何删除桌面的快捷方式》？

借花献佛，来自他人。
//在桌面上建立快捷方式
procedure TForm1.Button1Click(Sender: TObject);
var
tmpObject : IUnknown;
tmpSLink : IShellLink;
tmpPFile : IPersistFile;
PIDL : PItemIDList;
StartupDirectory : array[0..MAX_PATH] of Char;
StartupFilename : String;
LinkFilename : WideString;
begin
StartupFilename := 'c:/windows/notepad.exe';
tmpObject := CreateComObject(CLSID_ShellLink);//创建建立快捷方式的外壳扩展
tmpSLink := tmpObject as IShellLink;//取得接口
tmpPFile := tmpObject as IPersistFile;//用来储存*.lnk文件的接口
tmpSLink.SetPath(pChar(StartupFilename));//设定notepad.exe所在路径
tmpSLink.SetWorkingDirectory(pChar(ExtractFilePath(StartupFilename)));//设定工作目录
SHGetSpecialFolderLocation(0,
CSIDL_DESKTOPDIRECTORY,
PIDL);//获得桌面的Itemidlist
SHGetPathFromIDList(PIDL,
StartupDirectory);//获得桌面路径
LinkFilename := StartupDirectory + '/MyNotepad.lnk';
tmpPFile.Save(pWChar(LinkFilename),FALSE);//保存*.lnk文件
end;

uses activeX,comobj,shlobj;

const
IID_IPersistFile: TGUID =
(D1:$0000010B;D2:$0000;D3:$0000;D4$C0,$00,$00,$00,$00,$00,$00,$46));

function CreateLink(aPathObj,aPathLink,aDesc: string): boolean;
var sLink: IShellLink;
PersFile: IPersistFile;

begin
Result := false;
if SUCCEEDED(CoCreateInstance(CLSID_ShellLink, nil,
CLSCTX_INPROC_SERVER, IID_IShellLinkA, sLink)) then
begin
sLink.SetPath(PChar(aPathObj));
sLink.SetDescription(PChar(aDesc));
if SUCCEEDED(sLink.QueryInterface(IID_IPersistFile,PersFile)) then
begin
PersFile.Save(StringToOLEStr(aPathLink),TRUE);
Result := true;
end;
end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
if not CreateLink('command.com',
'c:/temp/mylink.lnk','description...') then
begin
// errorhandling
end;
end;

需引用单元shiobj
function PutselfToDesktop(TargetName,Mycaption,DispInfo:String):boolean;
{________________________________________________
| Mycaption：快捷方式标题 |
| TargetName：快捷方式指向的文件，需包含完整路径| |
| DispInfo：快捷方式提示信息 可为空 |
| win2000指向快捷方式时可显示win98下无用 |
|________________________________________________}
var
IObject : IUnknown;
ISLink : IShellLink;
IPFile : IPersistFile;
PIDL : PItemIDList;
InFolder : array[0..MAX_PATH] of Char;
TargetName : String;
LinkName : WideString;
begin
if not fileexists(TargetName) then Exit;
if mycaption='' then Exit;
IObject := CreateComObject(CLSID_ShellLink);
ISLink := IObject as IShellLink;
IPFile := IObject as IPersistFile;
with ISLink do begin
SetPath(pChar(TargetName));
SetWorkingDirectory
(pChar(ExtractFilePath(TargetName)));
SetDescription(pchar(DispInfo));
end;
// 在桌面上建立
SHGetSpecialFolderLocation(0, CSIDL_DESKTOPDIRECTORY, PIDL);
SHGetPathFromIDList(PIDL, InFolder);
LinkName := InFolder + '/'+mycaption+'.lnk';
IPFile.Save(PWChar(LinkName), false);
//在程序组中建立
SHGetSpecialFolderLocation(0,CSIDL_STARTMENU , PIDL);
SHGetPathFromIDList(PIDL, InFolder);
LinkName := InFolder + '/程序/'+mycaption+'.lnk';
IPFile.Save(PWChar(LinkName), false);
result:=true;
end;

我的这个保证能用，不能用不要给分哟：）））））））

为什么不认IShellLink;IPersistFile;
我加了shlobj...
是不是要加什么单元？？？？？？？？

需要加入uses shlobj;
删除其实是删掉个你建立的那个.lnk文件.

用我的方法绝对没有问题！别忘了把分分给我就是了！：））））
我的专家分好少呀！555555555555555555555555555

IPersistFile 在ACTIVEX单元;

shlobj单元

接受答案！每人都有分！
谢谢！
