    Question visual c++ error(s) "intellisense : expected an expression please help!

    hello,
    i'm having many errors in visual c++
    here's the code:
    (i'm trying to do something in openGL)

    Code:
    #include <StdAfx.h>                     
    #include <windows.h>                                                   // Header File For Windows

    #define pRenderer

    What is that supposed to accomplish? You've #defined it as nothing, then you try to dereference it.

    Beats me. I don't know why it's there or what it's supposed to be doing.

    If you're a noob, that code may be a little more than you're ready for.
