// BXFileDialog.cpp : implementation file
// 
// Windows 2000 / Office 2000 style file dialog.
// 
// This WILL work on Win 95 / 98 / NT 4 / NT 5 (2000) / WinME
// 
// Original code by Norm Almond []
//					David Wulff [[e-mail]]
// 
// Update History:
//    07 Sep 2000 - David Wulff, Opps, I lost the previous update history.
//    08 Sep 2000 - David Wulff, Lots of changes, most significant is the
//                  .. addition of an optional preview panel, allowing you
//                  .. to preview bitmap images before opening/saving.
//    14 Oct 2000 - Joel Bernard, Provided a better CenterWindow function.
//                  David Wulff, Fixed memory leaks, added support for
//                  .. previewing non-bitmap images. (code by Wes Rogers)
//                  Other misc. changes.
//                  Anatoly Danekin, Shortcut path resolution.
//    13 Dec 2000 - David Wulff, Added Visual Studio .NET look
//    24 Mar 2001 - David Wulff, miscellaneous drawing updates
//                  Tak^Shoran, working sizing support for Win 98/2000
//                  Identified very bad flickering problem
//    31 Mar 2001 - David Wulff, Fixed resizing so it will work for dialogs
//                  .. with preview panels.  Tidied up all of the code (it
//                  .. was a big mess) and added standard function headers.
//                  .. Removed compile-time only modification of sizing
//                  .. support and VS.NET style
