Recursive file search using C++ MFC?

What is the cleanest way to recursively search for files using C++ and MFC?

EDIT: Do any of these solutions offer the ability to use multiple filters through one pass? I guess with CFileFind I could filter on *.* and then write custom code to further filter into different file types. Does anything offer built-in multiple filters (ie. *.exe,*.dll)?

EDIT2: Just realized an obvious assumption that I was making that makes my previous EDIT invalid. If I am trying to do a recursive search with CFileFind, I have to use *.* as my wildcard because otherwise subdirectories won't be matched and no recursion will take place. So filtering on different file-extentions will have to be handled separately regardless.

Using CFileFind.

Take a look at this example from MSDN:

void Recurse(LPCTSTR pstr)
{
   CFileFind finder;

   // build a string with wildcards
   CString strWildcard(pstr);
   strWildcard += _T("\\*.*");

   // start working for files
   BOOL bWorking = finder.FindFile(strWildcard);

   while (bWorking)
   {
      bWorking = finder.FindNextFile();

      // skip . and .. files; otherwise, we'd
      // recur infinitely!

      if (finder.IsDots())
         continue;

      // if it's a directory, recursively search it

      if (finder.IsDirectory())
      {
         CString str = finder.GetFilePath();
         cout << (LPCTSTR) str << endl;
         Recurse(str);
      }
   }

   finder.Close();
}
