-// 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
+// initially as the main frame, and allows wxWidgets frames to be
// created subsequently.
//
// (1) Make MyApp::OnInit not create a main window.
//
// IMPORTANT NOTES:
//
-// (1) You need to set wxUSE_MFC to 1 in include/wx/msw/setup.h, which switches
-// off some debugging features and also removes the windows.h inclusion
-// in wxprec.h (MFC headers don't like this to have been included previously).
-// Set to 'Use MFC in a shared DLL' or add _AFXDLL to preprocessor settings.
-// Then recompile wxWindows and this sample.
+// (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) I can't get the sample to link and run using a static MFC library, only the DLL
-// version. Perhaps someone else is a wizard at working out the required settings
-// in the wxWin library and the sample; then debugging the assert problem may be
-// easier.
+// (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:
//
-// (3) Compiling wxWindows in DLL mode currently includes windows.h, so you must only
-// try linking wxWindows statically.
+// 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
+
+#include "stdafx.h"
