Sprites and D3D9

Hi! I been trying to solve this by my own, but it simply don't make any sence. I'm trying to do the required initializing of the necessary D3DX components, so I can use the Sprite interface and draw an image. The main code runs fine, but as soon as the loop reaches the Graphics class, it crashes. Here's my code: Graphics.cpp [source lang="cpp"] #include "Graphics.h" Graphics::Graphics(HWND hWnd) { d3d = Direct3DCreate9(D3D_SDK_VERSION); ZeroMemory(&d3dpp, sizeof(D3DPRESENT_PARAMETERS)); d3dpp.Windowed = true; d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD; d3dpp.hDeviceWindow = hWnd; d3dpp.BackBufferFormat = D3DFMT_X8R8G8B8; d3dpp.BackBufferWidth = 1280; d3dpp.BackBufferHeight = 800; D3DXCreateSprite(d3ddev, &sprite); d3d->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, hWnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING, &d3dpp, &d3ddev); } Graphics::~Graphics(void) { } // -------------------------------------------------------------------------------- // Name: Begin // Desc: // Rtrn: None // -------------------------------------------------------------------------------- void Graphics::Begin(void) { sprite->Begin(D3DXSPRITE_ALPHABLEND); } // -------------------------------------------------------------------------------- // Name: Draw // Desc: // Rtrn: None // -------------------------------------------------------------------------------- void Graphics::Draw(void) { } // -------------------------------------------------------------------------------- // Name: End // Desc: // Rtrn: None // -------------------------------------------------------------------------------- void Graphics::End(void) { sprite->End(); } [/source] Graphics.h [source lang="cpp"] #pragma once #include <d3d9.h> #include <d3dx9.h> #pragma comment (lib, "d3d9.lib") #pragma comment (lib, "d3dx9.lib") class Graphics { public: Graphics(HWND hWnd); ~Graphics(void); // -------------------------------------------------------------------------------- // Name: Begin // Desc: // Rtrn: None // -------------------------------------------------------------------------------- void Begin(void); // -------------------------------------------------------------------------------- // Name: Draw // Desc: // Rtrn: None // -------------------------------------------------------------------------------- void Draw(void); // -------------------------------------------------------------------------------- // Name: End // Desc: // Rtrn: None // -------------------------------------------------------------------------------- void End(void); private: LPDIRECT3D9 d3d; D3DPRESENT_PARAMETERS d3dpp; LPDIRECT3DDEVICE9 d3ddev; LPD3DXSPRITE sprite; }; [/source] Nothing is null here, right? Still I get this error on crash: Unhandled exception at 0x0fd49c2d in AvoidBall.exe: 0xC0000005: Access violation reading location 0xcdcdcdcd. The "green arrow" stops on the 19:th line: d3d->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, hWnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING, &d3dpp, &d3ddev); What am I doing wrong? I know that I've asked alot about this basic graphics code, but it simply won't work for me Please help!

It's the SQL Server Compact Edition Database File (33.6mb) and a folder called ipch(50.6mb). I havn't added them, they was put there automaticly when I created my project in Visual Studio.

the icph is part of the projects intelisense data base.
