How to add header file in Visul stidio 2008

If you write in your code something like #include "FileWrite.h" you need to make sure compiler can find that file. There are three options:

• FileWrite.h should either be in the same directory as your source code file (.cpp) or
• Path to that header file should should be listed in project's Properties (in C/C++ -> General -> Additional Include Directories) or
• Path could be set in your VisualStudio - add it to Include Files in Tools->Options->Projects and Solutions->VC++ Directories

Which of these options shell be used depends on whether that header originates from this project (1st option) or some other project (any of other two options).
