Texture won't load and I get an unhandled exception

I'm trying to get a sprite to appear on my screen in the pong game I'm making but there seems to be some sort of bug that occurs. Right after the line that loads the texture executes, I get an unhandled exception. Here's the code: Object.h #ifndef OBJECT_H #define OBJECT_H #include <d3d9.h> #include <d3dx9.h> #include <string> #include "Graphics.h" class Object { public: Object(); ~Object(); void setTexture( LPDIRECT3DTEXTURE9 t ); void setPosition( float x, float y ); LPDIRECT3DTEXTURE9 getTexture() { return this -> texture; } LPD3DXVECTOR3 getPosition() { return this -> position; } private: LPDIRECT3DTEXTURE9 texture; LPD3DXVECTOR3 position; }; #endif OBJECT_H Object.cpp #include "Object.h" #include "Globals.h" Object::Object() { texture = NULL; position = NULL; } Object::~Object() { RELEASE( texture ); delete position; position = NULL; } void Object::setTexture( LPDIRECT3DTEXTURE9 t ) { texture = t; } void Object::setPosition( float x, float y ) { position -> x = x; position -> y = y; } Graphics.h #ifndef GRAPHICS_H #define GRAPHICS_H #include "DxManager.h" #include <string> class Graphics { public: bool InitGraphics( HWND &window ); void StartScene(); void Render(); void EndScene(); void Update(); LPDIRECT3DTEXTURE9 LoadTexture( std::string file ); DxManager getD3DManager() { return this -> D3DManager; } private: DxManager D3DManager; }; #endif GRAPHICS_H Graphics.cpp #include "Graphics.h" #include "Globals.h" bool Graphics::InitGraphics( HWND &window ) { if( !D3DManager.InitD3D( window ) ) { GameOver = true; MessageBox( window, "Error initializing DirectX9", "Error", MB_OK ); return false; } return true; } void Graphics::StartScene() { D3DManager.getDirect3DDevice() -> Clear( 0, NULL, D3DCLEAR_TARGET, Black, 0.0f, 0 ); D3DManager.getDirect3DDevice() -> BeginScene(); D3DManager.getSpriteObject() -> Begin( D3DXSPRITE_ALPHABLEND ); } void Graphics::Render() { } void Graphics::EndScene() { D3DManager.getSpriteObject() -> End(); D3DManager.getDirect3DDevice() -> EndScene(); D3DManager.getDirect3DDevice() -> Present( NULL, NULL, NULL, NULL ); } void Graphics::Update() { StartScene(); Render(); EndScene(); } LPDIRECT3DTEXTURE9 Graphics::LoadTexture( std::string file ) { LPDIRECT3DTEXTURE9 texture; D3DXIMAGE_INFO info; D3DXGetImageInfoFromFile( file.c_str(), &info ); D3DXCreateTextureFromFileEx( D3DManager.getDirect3DDevice(), file.c_str(), info.Width, info.Height, 1, D3DPOOL_DEFAULT, D3DFMT_X8R8G8B8, D3DPOOL_DEFAULT, D3DX_DEFAULT, D3DX_DEFAULT, Transparent, &info, NULL, &texture ); return texture; } WinMain.cpp Graphics g; g.InitGraphics( window ); Object Ball; Ball.setTexture( g.LoadTexture( "Resources/Ball.png" ) ); Ball.setPosition( 500, 100 ); while ( GameOver != true ) { if ( PeekMessage( &message, NULL, 0, 0, PM_REMOVE ) ) { TranslateMessage( &message ); DispatchMessage( &message ); } //g.Update(); g.StartScene(); g.getD3DManager().getSpriteObject() -> Draw( Ball.getTexture(), NULL, NULL, Ball.getPosition(), White ); g.EndScene(); } Is there anything that I'm doing wrong? Thanks for the help in advance.

Ok so new problem now The program runs fine and the objects render. However when I close the program, there is an exception in the destructor of the Object class. I think it's because it's trying to delete something that was already deleted? Or is it something else? I think I need a way to sequentially delete everything in the game ( i.e Objects, then ObjectManager, then D3DManager ) but I'm not sure how I would do that?

Stack objects are destroyed in the reverse order they are created. Objects on the heap can be deleted in any order (although deleting those in reverse-order as well is generally good practice).

The D3D9 debug runtime (enabled in dxcpl.exe) can give you insight into unreleased resources.

So would dynamically creating Objects, ObjectManager, and D3DManager as pointers be a solution so that I can delete them in the right order manually when the program ends?
