Win32 vs. Win16
A few old computers out there are still running Windows 3.1. However, there's not much point in spending money writing new programs for obsolete technology. This edition of Programming with Microsoft Visual C++ .NET is about 32-bit programming for Windows 98/Me and Windows NT/2000/XP using the Win32 API. If you really need to do 16-bit programming, I suggest that you find an old copy of the second edition of this book.
