Direct x failing

I have the following code: HRESULT result = S_OK; ID3D11Device* g_pd3dDevice = NULL; IDXGISwapChain* g_pSwapChain = NULL; ID3D11DeviceContext* g_pImmediateContext = NULL; D3D_FEATURE_LEVEL FeatureLevelsSupported; RECT deminsions; GetClientRect(hwnd, &deminsions); LONG width = deminsions.right - deminsions.left; LONG height = deminsions.top - deminsions.bottom; DXGI_SWAP_CHAIN_DESC sd; ZeroMemory( &sd, sizeof( sd ) ); sd.BufferCount = 1; sd.BufferDesc.Width = static_cast<unsigned int>(width); sd.BufferDesc.Height = static_cast<unsigned int>(height); sd.BufferDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM; sd.BufferDesc.RefreshRate.Numerator = 60; sd.BufferDesc.RefreshRate.Denominator = 1; sd.BufferUsage = DXGI_USAGE_RENDER_TARGET_OUTPUT; sd.OutputWindow = hwnd; sd.SampleDesc.Count = 1; sd.SampleDesc.Quality = 0; sd.Windowed = TRUE; D3D_FEATURE_LEVEL FeatureLevelsRequested[] = { D3D_FEATURE_LEVEL_9_1, D3D_FEATURE_LEVEL_9_2, D3D_FEATURE_LEVEL_9_3, D3D_FEATURE_LEVEL_10_0, D3D_FEATURE_LEVEL_10_1, D3D_FEATURE_LEVEL_11_0 }; result = D3D11CreateDeviceAndSwapChain( NULL, D3D_DRIVER_TYPE_HARDWARE, NULL, 0, FeatureLevelsRequested, 3, D3D11_SDK_VERSION, &sd, &g_pSwapChain, &g_pd3dDevice, &FeatureLevelsSupported, &g_pImmediateContext ); if(FAILED(result)) return -1; ID3D11RenderTargetView* p_BackBufferTarget = NULL; ID3D11Texture2D* p_RT; result = g_pSwapChain->GetBuffer(0, __uuidof(ID3D10Texture2D), (LPVOID*)&p_RT); if(FAILED(result)) return -2; result = g_pd3dDevice->CreateRenderTargetView(p_RT, 0, &p_BackBufferTarget); if(FAILED(result)) return -3; if(p_RT) p_RT->Release(); p_RT = NULL; g_pImmediateContext->OMSetRenderTargets(1, &p_BackBufferTarget, 0); D3D11_VIEWPORT viewport; viewport.Height = static_cast<float>(height); viewport.Width = static_cast<float>(width); viewport.MaxDepth = 1.0f; viewport.MinDepth = 0.0f; viewport.TopLeftX = 0.0f; viewport.TopLeftY = 0.0f; g_pImmediateContext->RSSetViewports(1, &viewport); UpdateWindow(hwnd); the program fails and returns -1 which means there is something wrong with this: result = D3D11CreateDeviceAndSwapChain( NULL, D3D_DRIVER_TYPE_HARDWARE, NULL, 0, FeatureLevelsRequested, 3, D3D11_SDK_VERSION, &sd, &g_pSwapChain, &g_pd3dDevice, &FeatureLevelsSupported, &g_pImmediateContext ); But I'm not sure what?

Okay changed the height calculation, changed the feature level count to 6 and re arranged the array. Still crashes.

Your program didn't crash before. It returned -1. Why did you remove the return statement?

I'm on windows 7 ultimate(64 bit). If it runs okay on your system, it probably means I can't run direct x 11 or something :/

Did you even try to debug it yourself before comming to this conclusion. Did you try to run any of the DX11 Samples and see whether it is using Hardware or Ref mode.

I didn't come to a conclusion.. I just think it might be a reason. What examples?

I removed the return -1 because I wanted to see the message displayed when it failed.
