-// This sample pops up an initial wxWindows frame, with a menu item
+// This sample pops up an initial wxWidgets frame, with a menu item

 // that allows a new MFC window to be created. Note that CDummyWindow
 // that allows a new MFC window to be created. Note that CDummyWindow

-// is a class that allows a wxWindows window to be seen as a CWnd
+// is a class that allows a wxWidgets window to be seen as a CWnd

 // for the purposes of specifying a valid main window to the
 // MFC initialisation.
 //
 // You can easily modify this code so that an MFC window pops up

 // You can easily modify this code so that an MFC window pops up

-// created subsequently:
+// initially as the main frame, and allows wxWidgets frames to be
+// created subsequently.

 //
 //

-// (1) Make MyApp::OnInit return NULL, not create a window.
-// (2) Restore the MFC code to create a window in InitInstance, and remove
+// (1) Make MyApp::OnInit not create a main window.
+// (2) Make MFC's InitInstance create a main window, and remove

 //     creation of CDummyWindow.
 //
 //     creation of CDummyWindow.
 //

-// IMPORTANT NOTE: to compile this sample, you must first edit
-// wx/src/msw/wx_main.cc, set NOWINMAIN to 1, and remake wxWindows
-// (it only needs to recompile wx_main.cc).
-// This eliminates the duplicate WinMain function which MFC implements.
+// This can be accomplished by setting START_WITH_MFC_WINDOW to 1 below.
+
+#define START_WITH_MFC_WINDOW 0
+
+//
+// IMPORTANT NOTES:
+//
+// (1) You may need to set wxUSE_MFC to 1 in include/wx/msw/setup.h but
+//     normally this shouldn't be needed any longer, i.e. it works without
+//     it for me (VZ)
+//
+// (2) You should link with MFC DLL, not static libraries: or, to use static
+//     run-time libraries, use this command for both building wxWidgets and
+//     the sample:
+//
+//     nmake -f makefile.vc BUILD=debug SHARED=0 DEBUG_RUNTIME_LIBS=0 RUNTIME_LIBS=static all
+//
+//     Unless the run-time library settings match for wxWidgets and MFC, you
+//     will get link errors for symbols such as __mbctype, __argc, and __argv
+//
+// (3) If you see bogus memory leaks within the MSVC IDE on exit, in this
+//     sample or in your own project, you must be using __WXDEBUG__ +
+//     WXUSINGDLL + _AFXDLL
+//     Unfortunately this confuses the MSVC/MFC leak detector. To do away with
+//     these bogus memory leaks, add this to the list of link objects, make it
+//     first: mfc[version][u]d.lib
+//     -  [version] -> 42 or 70 or 80 etc
+//     -  u if using Unicode
+
+// Disable deprecation warnings from headers included from stdafx.h for VC8+
+#ifndef _CRT_SECURE_NO_WARNINGS
+    #define _CRT_SECURE_NO_WARNINGS
