Bonjour à tous,
je débutes en c++ directx et j'avoue que j'ai un peu (beaucoup) de mal...
Dans le code suivant je n'arrives pas à initilalisé la variable device qui est du type IDirect3DDevice9. Pourtant je pense utiliseé la fonction CreateDevice correctement. Si quelqu'un pouvait m'aider ce serait trés sympa

Voici le code :
#include <windows.h>
#include <d3d9.h>
#include <d3dx9.h>
#include <iostream>
/* Declare Windows procedure */
LRESULT CALLBACK WindowProcedure(HWND, UINT, WPARAM, LPARAM);
/* Make the class name into a global variable */
char szClassName[ ] = "WindowsApp";
// ***********************
// variable directx
IDirect3D9 *D3D ;
IDirect3DDevice9 *device ;
// ***********************
// handle sur la fenetre
HWND hwnd;
// initialisation de directx
void D3DInit(){

presentParameters.BackBufferHeight = displayMode.Height ;
presentParameters.BackBufferFormat = displayMode.Format ;
presentParameters.BackBufferCount = 1 ;
presentParameters.MultiSampleType = D3DMULTISAMPLE_NONE ;
presentParameters.SwapEffect = D3DSWAPEFFECT_DISCARD ;
presentParameters.hDeviceWindow = NULL ;
presentParameters.Windowed = TRUE ;

D3D->CreateDevice (D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, hwnd,D3DCREATE_HARDWARE_VERTEXPROCESSING, &presentParameters,&device) ;
}
