Help with making header files

Hello everyone,
I just finished writing this incredibly long code, and I'm really exited about it. As always, it is impossible to get zero errors in the first compile. I was expecting at least a hundred, but instead I was suprised to see only about five. I've fixed all of the bugs up until one of them. The program uses a header file that i create (i have MSVC++.NET, so i put it into the solution), and it can't seem to find it. I use it by saying "#include <evolution.h>"

I'm not sure if I have to top part of the header file written correctly:
#IF NDEF "evolution.h"
DEFINE "evolution.h"
#ENDIF

If anyone can offer any assistance, it would be nice.

The way to do is this.

Code:

---

#ifndef evolution_h
#define evolution_h

//header goods here

#endif//evolution_h

---

Thanks

If you're including a header that belongs to the compiler libs use
#include <header>
If your using your own header use - note: that the header file name can be a relative path
#include "header"
#include "..\dir\header"
