Hi there!
I migrated from Direct3D to OpenGL a few days ago, i'm trying to obtain my first rendering.
I already have a problem around using VBOs.

GLuint VertexBuffer;

Visual C++ generates this error:

First-chance exception at 0x00000000 in myprogr.exe:
0xC00000005: Access violation execeuting location 0x00000000

within "glGenBuffers" line.

The entire source is:

void InitOpenGL()
hDC = GetDC(GameWindow);

pfd.nSize = sizeof(pfd);
pfd.nVersion = 1;
pfd.iPixelType = PFD_TYPE_RGBA;
pfd.cColorBits = 32;
pfd.cDepthBits = 24;
pfd.iLayerType = PFD_MAIN_PLANE;
int pixelFormat = ChoosePixelFormat(hDC,&pfd);

hRC = wglCreateContext(hDC);

GLuint VertexBuffer;

InitOpenGL is called inside WinMain, just before the beginning of the main loop
(while(1) {...} ) where windows messages are controlled and rendering is processed.

I've already checked my OpenGL version (glGetString(GL_VERSION) returns "2.1.8395 Release") against OpenGL specifications and
glGenBuffers should be supported..[/spoiler]
edit: Never mind! I had to place glewInit() after the activation of OpenGL.
