 // IMPORTANT NOTES:
 //
 //
 // 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).
-// 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) 10/3/2000, wxWindows 2.1.14: unfortunately there is an assert when
-// the sample tries to create an MFC window. Any suggestions welcome. It may be
-// a problem with conflicting project settings. Ignoring the assert (several times)
-// allows the sample to continue. In release mode the asserts don't happen.
+// (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) I can't get the sample to link 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.
+//     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
