Unit zur Verwendung von SHGetKnownFolderPath

[KodeZwerg]

Schnell rumgewurschtelt, nun sollte es Unicode sein?

Delphi-Quellcode:

const FILE_NAME_NORMALIZED = $0;
//Function GetFinalPathNameByHandleA(hFile: THandle; lpszFilePath: LPSTR; cchFilePath: DWORD; dwFlags: DWORD): DWORD; stdcall; external 'Kernel32.dll';
Function GetFinalPathNameByHandleW(hFile: THandle; lpszFilePath: LPWSTR; cchFilePath: DWORD; dwFlags: DWORD): DWORD; stdcall; external 'Kernel32.dll';

function _FileGetSymLinkTarget( const APathToLink : string; var ATarget : string ) : boolean;
  var
    LinkHandle: THandle;
    TargetName: array [0..OFS_MAXPATHNAME-1] of WideChar;
  begin
    ATarget := '';
    LinkHandle := CreateFileW( PWideChar(APathToLink), 0, FILE_SHARE_READ, nil,
        OPEN_EXISTING, FILE_FLAG_BACKUP_SEMANTICS, 0);
    Win32Check(LinkHandle <> INVALID_HANDLE_VALUE);
    try
      Result := GetFinalPathNameByHandleW(LinkHandle, @TargetName, OFS_MAXPATHNAME, FILE_NAME_NORMALIZED) > 0;
      if Result then
        begin
        ATarget := TargetName;
        if Pos( '\\?\UNC\', ATarget ) = 1 then
           begin
           Delete( ATarget, 1, 8 );
           Insert( '\\', ATarget, 1 );
           end
          else
          if Pos( '\\?\', ATarget ) = 1 then
             Delete( ATarget, 1, 4 );
        end;
    finally
      CloseHandle(LinkHandle);
    end;
  end;

procedure TForm1.FormCreate(Sender: TObject);
var
  s: String;
begin
  s := '';
  _FileGetSymLinkTarget('c:\programme',s);
  ShowMessage(s);
end;
