How to include header files in Visual Studio 2008?

Question

I am currently trying to compile a simple program that includes two header files. I see them in the Solution Explorer, where I included them through \"include existing files\".

Answer 1

There are two ways to do this.

1) Only for the current project

Select your project -> properties -> C/C++ -> General -> Additional Include Directories -
Include your header file directory.

2) For all projects

Tools -> Options -> VC++ Directories -> Include files - Add the header file directory.

Refrain from using 2, as it would be difficult to figure out dependencies for a project when compiling it on a system different than yours.
