Hi
I'm trying to work through Ex9_16. I think the problem is in GlassBox.h
#include "Box.h"
This file is not found because it is not there. I finally downloaded the code but it seems to have the same problem as what I typed from the book.

By the way removing #include "Box.h" solves the file not found problem but I had to add a path to the properties page of Ex9_16 to get the program to compile

I too had problems around EX9_16lib.dll. finally resolved it by putting a copy of EX9_16lib.dll in both the source folder and the debug folder. The debug folder gave a problem, as I have two. I am using Visual Studio 2005 in its default state. Hence it appears to create a hierarchy of project files. For example: If I create a new project EX9_16, I get:
-EX9_16
   EX9_16

Once I start debugging, I get:
-EX9_16
   -EX9_16
       Debug

and once compiled (I think; maybe earlier)
-EX9_16
    Debug
    -EX9_16
        Debug

My initial problems came about by putting the dll in the third level down debug; wrong one. I needed it in the second level debug, where the exe is -and a copy in the second level down EX9_16 folder in order to compile.

(The hierarchy maybe a problem of my own making; perhaps I will find out as I proceed.)

I hope that this helps others.

(Edit later: I think my directory confusion comes about because the top level is the solution folder and the second level, above, is the project folder. Confusion arises as both have the same names.)
