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?
