I installed GLEW and put the files where the website told me to do but when I run my project, I get these errors:

1>main.obj : error LNK2001: unresolved external symbol __imp____glewDisableVertexAttribArray
1>main.obj : error LNK2001: unresolved external symbol __imp____glewVertexAttribPointer
1>main.obj : error LNK2001: unresolved external symbol __imp____glewBindBuffer
1>main.obj : error LNK2001: unresolved external symbol __imp____glewEnableVertexAttribArray
1>main.obj : error LNK2019: unresolved external symbol __imp__glewGetErrorString@4 referenced in function _main
1>main.obj : error LNK2019: unresolved external symbol __imp__glewInit@0 referenced in function _main
1>main.obj : error LNK2001: unresolved external symbol __imp____glewBufferData
1>main.obj : error LNK2001: unresolved external symbol __imp____glewGenBuffers

This is where I put my files:

bin/glew32.dll to system 32
lib/glew32.lib to {VC Root}/Lib
include/GL/glew.h to {VC Root}/Include/GL
include/GL/wglew.h to {VC Root}/Include/GL

And did you link the glew32.lib with your project?

No I put these few lines of code in and it seemed to work however I'm not really sure what they do. Can I link GLEW without them?

[source lang="cpp"]#pragma once

#include <glew.h>
#pragma comment(lib, "glew32.lib")

#pragma comment(lib, "opengl32.lib")[/source]

It's basically a way of linking a library in code.

To do it from the IDE, you just add them in the additional dependencies field in your project properties.
