why does my window close when i run it.
the code compiled and linked just fine
so why des it not open
here is the code
#include <windows.h> // windows header file
#include <d3d8.h> // direct 3D header file
// thease are constants for designing the window

// another variable for fullscreen mode
bool g_bFullscreen;
// More variabels and pointers but these are for direct X
IDirect3D8 *g_pDirect3D;

// for you techies its a variable to hold function call results
