CFileInfoArray: A class for gathering file information recursively through directories

/**
 * @doc FCOMPARE
 * @module FCompareDlg.h - Interface for the FCompare dialog class application |
 * This application is a sample of CFileInfo and CFileInfoArray usage

 * 
 * Updates:<nl>
 *  1999-4-30 ATL: Corrected a bug when setting timers: requested timer was id 0 and MSDN help states
 *                 that the timer id must be greater than 0. This bug was pointed out to me by 
 *                 Javier Maura (�although the timer _does_ work even if its id is 0!!!).
 *                 The user is also warned about progress not being reported if SetTimer fails.
 *
 * Keep this comment if you redistribute this file. And credit where credit's due!
