如何在Windows桌面上创建文件快捷方式（* .lnk文件）？ [英] How to create a file shortcut (*.lnk file) on desktop in Windows?

问题描述

function GetDesktopFolder: string;
var
  buf: array[0..MAX_PATH] of Char;
  pidList: PItemIDList;
begin
  Result := StrNoDesktopFolderFo;
  SHGetSpecialFolderLocation(Application.Handle, CSIDL_DESKTOP, pidList);
  if (pidList <> nil) then
    if (SHGetPathFromIDList(pidList, buf)) then
      Result := buf;
end;

procedure p;
var
  i: Integer;
  IObject: IUnknown;
  ISLink: IShellLink;
  IPFile: IPersistFile;
  PIDL: PItemIDList;
  InFolder: array[0..MAX_PATH] of Char;
  TargetName: string;
  LinkName: string;
begin
  TargetName := 'c:\folder\exeFile.exe';//hardcoded example

  IObject := CreateComObject(CLSID_ShellLink) ;
  ISLink := IObject as IShellLink;
  IPFile := IObject as IPersistFile;

  with ISLink do
  begin
    SetDescription('what ever');
    SetPath(pChar(TargetName)) ;
    SetWorkingDirectory(pChar(ExtractFilePath(TargetName))) ;
  end;

  SHGetSpecialFolderLocation(0, CSIDL_DESKTOPDIRECTORY, PIDL) ;
  SHGetPathFromIDList(PIDL, InFolder) ;

  LinkName := getDesktopFolder+'\';
  i := ;

  LinkName:= linkname+ExtractFileName(TargetName)+'.lnk';

  if LinkName = StrNoDesktopFolderFo then
    Exit;
  if not FileExists(LinkName) then
    IPFile.Save(PWChar(LinkName), False);

  Application.Terminate;
end;

上面的代码在Delphi中导致了很多错误，不能运行两次...

The above code causes a lot of errors in Delphi and cannot run twice...

任何想法？

Btw。来源不是我的，它是从网上的地方拿起来的。

Btw. the source is not originally mine, it was picked up from places on the web.

这种方式

uses
  ShlObj, ComObj, ActiveX;

function GetDesktopFolder: string;
var
  PIDList: PItemIDList;
  Buffer: array [0..MAX_PATH-1] of Char;
begin
  Result := '';
  SHGetSpecialFolderLocation(Application.Handle, CSIDL_DESKTOP, PIDList);
  if Assigned(PIDList) then
    if SHGetPathFromIDList(PIDList, Buffer) then
      Result := Buffer;
end;

function CreateDesktopShellLink(const TargetName: string): Boolean;
var
  IObject: IUnknown;
  ISLink: IShellLink;
  IPFile: IPersistFile;
  PIDL: PItemIDList;
  LinkName: string;
  InFolder: array [0..MAX_PATH-1] of Char;
begin
  Result := False;

  IObject := CreateComObject(CLSID_ShellLink);
  ISLink := IObject as IShellLink;
  IPFile := IObject as IPersistFile;

  with ISLink do
  begin
    SetDescription('Description ...');
    SetPath(PChar(TargetName));
    SetWorkingDirectory(PChar(ExtractFilePath(TargetName)));
  end;

  SHGetSpecialFolderLocation(0, CSIDL_DESKTOPDIRECTORY, PIDL);
  SHGetPathFromIDList(PIDL, InFolder) ;

  LinkName := IncludeTrailingBackslash(GetDesktopFolder);
  LinkName := LinkName + ExtractFileName(TargetName) + '.lnk';

  if not FileExists(LinkName) then
    if IPFile.Save(PWideChar(LinkName), False) = S_OK then
      Result := True;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  if CreateDesktopShellLink('C:\Folder\ExeFile.exe') then
    ShowMessage('Link has been created ...');
end;
