Query: Watch out

The source code in chapter 3 does not compile under VC++ 6. The author uses STL libraries for <string> and <iostream> but does not add: using namespace std; in his code in the book, but he does on the CDROM. His code on the CD ROM greatly varies from what is in the book. What gives?! Of course Waite Press (MCP) does not offer any "errata" or updates. I will NEVER buy an MCP book again! Also in chapter three the author says to compile the DLL....where did this DLL suddendly come from? I though we were making console EXEs? No help, not worth it.
