D3D10CreateDeviceAndSwapChain(）始终失败，DXGI_ERROR_INVALID_CALL

D3D10CreateDeviceAndSwapChain() always failing with DXGI_ERROR_INVALID_CALL

我正在创建一个隐藏窗口，并希望获得一个指向IDXGISwapChain::Present()的指针。问题是我无法获得有效的Direct3D10设备，也无法获得有效交换链。

HWND hwnd = CreateWindow(TEXT("flhiSTATIC"), TEXT("flh DXGI Window"), WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, 640, 480, 0, NULL, NULL, 0);
DXGI_SWAP_CHAIN_DESC scd;
ZeroMemory(&scd, sizeof(scd));
scd.BufferCount = 2;
RECT rcWnd;
GetClientRect(hwnd, &rcWnd);
scd.BufferDesc.Width = rcWnd.right - rcWnd.left;
scd.BufferDesc.Height = rcWnd.bottom - rcWnd.top;
scd.BufferDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM; // also tried DXGI_FORMAT_R8G8B8A8_UNORM_SRGB
scd.BufferDesc.ScanlineOrdering = DXGI_MODE_SCANLINE_ORDER_UNSPECIFIED;
scd.BufferDesc.Scaling = DXGI_MODE_SCALING_CENTERED;
scd.BufferDesc.RefreshRate.Numerator = 60;
scd.BufferDesc.RefreshRate.Denominator = 1;
scd.BufferUsage = DXGI_USAGE_RENDER_TARGET_OUTPUT;
scd.OutputWindow = hwnd;
scd.SampleDesc.Count = 1;
scd.SampleDesc.Quality = 0;
scd.Windowed = TRUE;
scd.SwapEffect = DXGI_SWAP_EFFECT_DISCARD;
pD3D10CreateDeviceAndSwapChain = reinterpret_cast<D3D10CREATEDEVICEANDSWAPCHAIN_PROC *>(GetProcAddress(d3d10, "D3D10CreateDeviceAndSwapChain"));
HRESULT hr = pD3D10CreateDeviceAndSwapChain(NULL /*pAdapter*/, D3D10_DRIVER_TYPE_HARDWARE, NULL, D3D10_CREATE_DEVICE_DEBUG, D3D10_SDK_VERSION, &scd, &pSwapChain, &pDev);
// this guy always fails with 0 in both pSwapChain and pDev...

知道上面的代码可能出了什么问题吗？

我完全忘记了创建或分配预先存在的窗口类的必要性：（

这就是问题所在；经验教训-始终检查所有调用的返回代码。

编辑

我完全忘记了使用有效窗口类调用CreateWindow，该类要么是我以前注册的，要么是由某人在当前模块中注册的。
