STL breaks after installing Microsoft Security Advisory 973882

After installing through Microsoft Update Vulnerabilities in Microsoft Active Template Library (ATL) Could Allow Remote Code Execution STL broke with the following error:
c:\program files\microsoft visual studio 9.0\vc\include\xutility(2764) : error C3861: '_Swap_adl': identifier not found

Most probably, this is caused by accidentally deleted the following function:
template inline
   void _Swap_adl(_Ty& _Left, _Ty& _Right)
   { // exchange values stored at _Left and _Right, using ADL
      swap(_Left, _Right);
   }
Placing this code back somewhere (I placed directly in xutility), fixed this problem. Not sure if there are any side effects. Most probably Microsoft will issue another fix.

Batch script to test if folder / directory is empty

Yesterday I needed a Dos batch script to check if folder is empty. A little Google search revealed some methods:

  • Using dir and find commands, does not work on non-english Windows versions: www.computing.net
  • Using dir command with /a-d, does not work for folders: www.computing.net
  • Using dir and findstr commands, does not work on non-english Windows versions: windowsitpro.com

If you want something done right do it yourself. Here is a my script:
@echo off
for /F %%i in ('dir /b "c:\test directory\*.*"') do (
   echo Folder is NON empty
   goto :EOF
)
echo Folder is empty or does not exist

Update Sep 21, 2011 – added “or does not exist”. Thanks to the Thump.
Update Jul 5, 2013 – for more code examples see the comments!
