Original Post
hi i have just bought the book " tricks of the game programming gurus ". i have typed out the freakout programme in the first part of the book and i keep getting 2 errors. first i am using visual C++ 6.0 standard edition compiler and i have installed the
directX 6.1 sdk as well and i have included the ddraw.lib into my project as well. but i keep getting 2 errors coming up which are.
here is the code that im using from the book:
// BLACKBOX.h - header file for demo game engine library
// watch for multiple inclusions

and these are the errors can any one help me to sort this problem out please:
