Cannot open include file: 'basewin.h': No such file or directory

Question

I'm trying to figure out how I can find where to either download the file set or get rid of this error. This elusive 'basewin.h' is nowhere to be found. So I don't know if I'm missing a library or what. I've also tried switching around the 'windows.h' and 'basewin.h' statements. I've tried disabling precompiled headers. Apparently this file holds the information for the "basewindow" class.

I'm using visual studio 2013 and I'm using a win32 project.I'm trying to run the example from the microsoft tutorial website http://msdn.microsoft.com/en-us/library/windows/desktop/ff684181(v=vs.85).aspx. Any help would be very much appreciated. Here is the code:

    #include <windows.h>
#include <d2d1.h>
#pragma comment(lib, "d2d1")

The page you linked says: "The program re-uses the BaseWindow class that was defined in the topic Managing Application State".

That link contains the code for the BaseWindow class, which you should put in basewin.h.
