Inability to create a DirectX device and swapchain

Question

I am having problems retrieving the swapchain and device from directx. additional information is in code

void GXDX::StartUp(HWND* mainWindow,int w, int h) { //width and height are members of GXDX width = w; //contains the width height = h; //contains the height this->mainWindow = mainWindow; // Is a handle to the main window. it is usually something //like : unusual -735313406 ID3D10Texture2D *backBufferSurface; DXGI_SWAP_CHAIN_DESC swapChainDesc; swapChainDesc.BufferCount = 2; swapChainDesc.BufferDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM; swapChainDesc.BufferDesc.RefreshRate.Numerator = 60; swapChainDesc.BufferDesc.RefreshRate.Denominator = 1; swapChainDesc.BufferDesc.Width = width; swapChainDesc.BufferDesc.Height = height; swapChainDesc.SampleDesc.Count = 1; swapChainDesc.SampleDesc.Quality = 0; swapChainDesc.OutputWindow = *mainWindow; swapChainDesc.Windowed = TRUE; D3D10_DRIVER_TYPE driverType = D3D10_DRIVER_TYPE_HARDWARE; HRESULT hr = D3D10CreateDeviceAndSwapChain(NULL,driverType,NULL,0, D3D10_SDK_VERSION, &swapChainDesc,&swapChain,&dxDevice); if(FAILED(hr))//Error is here throw GXVideoException(L"Problems retrieving directX device"); }

[EDIT]

Prior to Goz's answer, I checked further debugging details, and this is what was received

 DXGI Error: IDXGIFactory::CreateSwapChain: SwapEffect is unknown. 

which I assume I did not add swapeffect attributes. I will do it and check it out

Answer 1

Stupid to me. I previously mentioned in a comment that both books I read did not include the swapchain effect property. I knew that something was out, whether I included the swap chain or not.

But I also notice that both books reset the description of the swap chains. Make it safer to leave properties. So I added the following

 SecureZeroMemory(&swapChainDesc, sizeof(swapChainDesc)); 

and it worked. Put it aside, I have to add a swapchain effect property. But for this reason, the book decided not to do this, I still do not understand.

Do not try to pass a pointer to your HWND. You must pass HWND as not a pointer. Other than that, I don't see anything massive wrong.

This is what DXErrorLookup says about your error:

 HRESULT: 0x887a0001 (2289696769) Name: DXGI_ERROR_INVALID_CALL Description: The application has made an erroneous API call that it had enough information to avoid. This error is intended to denote that the application should be altered to avoid the error. Use of the debug version of the DXGI.DLL will provide run- time debug output with further information. Severity code: Failed Facility Code: FACILITY_DXGI (2170) Error Code: 0x0001 (1) 

So, have you considered using the debug version of DXGI to find out what the error is?

Btw my working initialization of the DX10 is as follows (Warning a lot of code!):

  HRESULT hr = S_OK; // Wrong init params passed in. if ( pParams->paramSize != sizeof( D3D10InitParams ) ) return false; // Upgrade the initparams to the correct version mInitParams = *(D3D10InitParams*)pParams; // Create factory. IDXGIFactory* pFactory = NULL; if ( FAILED( CreateDXGIFactory( __uuidof( IDXGIFactory ), (void**)&pFactory ) ) ) { return false; } if ( FAILED( pFactory->MakeWindowAssociation( mInitParams.hWnd, 0 ) ) ) { return false; } HWND hTemp; pFactory->GetWindowAssociation( &hTemp ); // Enumerate adapters. unsigned int count = 0; IDXGIAdapter * pAdapter; std::vector<IDXGIAdapter*> vAdapters; while( pFactory->EnumAdapters( count, &pAdapter ) != DXGI_ERROR_NOT_FOUND ) { vAdapters.push_back( pAdapter ); count++; } unsigned int selectedAdapter = mInitParams.display; if ( vAdapters.size() > 1 ) { // Need to handle multiple available adapters. } // Release all other adapters. count = 0; unsigned int max = (unsigned int)vAdapters.size(); while( count < max ) { if ( count != selectedAdapter ) { vAdapters[count]->Release(); } count++; } // Device should support all basic DX10 features. // Caps does not support enough basic features. //if ( !CheckCaps( &caps ) ) // return false; // Create the D3D 10 device.

Hope this helps!

Answer 3

The following code worked for me (I am using Microsoft Visual Studio Express 2012 for Windows Desktop)

 DXGI_SWAP_CHAIN_DESC swapChainDesc; swapChainDesc.BufferDesc.Width = width; swapChainDesc.BufferDesc.Height = height; swapChainDesc.BufferDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM; swapChainDesc.BufferDesc.RefreshRate.Numerator = 60; swapChainDesc.BufferDesc.RefreshRate.Denominator = 1; swapChainDesc.SampleDesc.Count = 1; swapChainDesc.SampleDesc.Quality = 0; swapChainDesc.BufferUsage = DXGI_USAGE_RENDER_TARGET_OUTPUT; swapChainDesc.BufferCount = 1; swapChainDesc.OutputWindow = hWnd; swapChainDesc.Windowed = true; swapChainDesc.SwapEffect = DXGI_SWAP_EFFECT_DISCARD; swapChainDesc.Flags = 0; ID3D11Device *pDevice = 0; ID3D11DeviceContext *pContext = 0; IDXGISwapChain *pSwapChain = 0; HRESULT result; result = D3D11CreateDeviceAndSwapChain(NULL, driverType, NULL, D3D11_CREATE_DEVICE_SINGLETHREADED, featureLevel, totalFeatureLevel, D3D11_SDK_VERSION, &swapChainDesc, &pSwapChain, &pDevice, &currentFeatureLevel, &pContext); 

So you can just try adding more attributes to swapChainDesc.
