+/////////////////////////////////////////////////////////////////////////////
-// *** 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 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 wxWidgets and this sample.
+//
+// (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.
+//
+// (3) Compiling wxWidgets in DLL mode currently includes windows.h, so you must only
+// try linking wxWidgets statically.
// For compilers that support precompilation, includes "wx/wx.h".
