visual studio header

I'm a newbie to visual studio. I am follow开发者_运维百科ing a tutorial to learn C++ and they have provided some headers for the course. So when i work with projects i include the headers in the header folder of the solution explorer on the left. But when i run the program, i get errors that the headers are no where to be found. pls help.

Thanks in advance :)

Use menu Tools, Options, Projects and Solutions, VC++ Directories to set the path where VS will seach the headers.
