+// Name: mfctest.cpp
+// Purpose: Sample to demonstrate mixing MFC and wxWidgets code
+// Author: Julian Smart
+// Id: $Id$
+// Copyright: (c) Julian Smart

+/////////////////////////////////////////////////////////////////////////////
-// *** MODIFIED BY JULIAN SMART TO DEMONSTRATE CO-EXISTANCE WITH wxWINDOWS ***
-//
-// 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
-// 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
-// initially as the main frame, and allows wxWindows frames to be
-// 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.
//
-// 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
+//
+// (4) Unicode builds may produce the linker error "unresolved external symbol _WinMain@16".
+// MFC requires you to manually add the Unicode entry point to the linker settings,
+// Entry point symbol -> wWinMainCRTStartup
