title: visual studio 2012 adding new header file
body: <p>In Visual Studio 2012 (C++ environment), for a Win32 console application, I need to include a new header file to my project. I tried copying the files in the project's location but that is of no help. The file is <code>iGraphics.h</code> and it is shown in the header files list but does not compile. What should be the correct approach?</p>
