c++ - ' 错误代码 : E_FAIL ' when creating DirectX 10 Device and Swap Chain

Question

我正在学习“使用 Direct3D 10.0 进行 3D 游戏编程简介”一书的一些简单 DX 教程。我在使用D3D10CreateDeviceAndSwapChain函数的时候遇到了一些问题。以下是代码:

        // Fill out a DXGI_SWAP_CHAIN_DESC to describe our swap chain.

    DXGI_SWAP_CHAIN_DESC sd;


    sd.BufferDesc.Width  = mClientWidth;
    sd.BufferDesc.Height = mClientHeight;

    sd.BufferDesc.RefreshRate.Numerator = 60;
    sd.BufferDesc.RefreshRate.Denominator = 1;

    sd.BufferDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM;
    sd.BufferDesc.ScanlineOrdering = DXGI_MODE_SCANLINE_ORDER_UNSPECIFIED;
    sd.BufferDesc.Scaling = DXGI_MODE_SCALING_UNSPECIFIED;

    // No multisampling.
    sd.SampleDesc.Count   = 1;
    sd.SampleDesc.Quality = 0;

    sd.BufferUsage  = DXGI_USAGE_RENDER_TARGET_OUTPUT;
    sd.BufferCount  = 1;
    sd.OutputWindow = mhMainWnd;
    sd.Windowed     = true;
    sd.SwapEffect   = DXGI_SWAP_EFFECT_DISCARD;
    sd.Flags        = 0;


    // Create the device.

    UINT createDeviceFlags = 0;

#if defined(DEBUG) || defined(_DEBUG)  
    createDeviceFlags |= D3D10_CREATE_DEVICE_DEBUG;
#endif

    HR( D3D10CreateDeviceAndSwapChain(
            0,                 //default adapter

            md3dDriverType,
            //D3D10_DRIVER_TYPE_HARDWARE,

            0,                 // no software device
            createDeviceFlags, 

            D3D10_SDK_VERSION,
            &sd,
            &mSwapChain,
            &md3dDevice) );

错误信息是:

错误代码:E_FAIL (0x80004005) 调用:D3D10CreateDeviceAndSwapChain(.....

当我将 D3D10CreateDeviceAndSwapChain 的参数“createDeviceFlags”更改为 0 时，它就起作用了。但为什么？？我想知道原因，谁能告诉我？？？

MSDN 说

To create a device that supports the debug layer, you must install the DirectX SDK (to get D3D10SDKLayers.DLL), and then specify the D3D10_CREATE_DEVICE_DEBUG flag when calling D3D10CreateDevice.

那么，您安装了 SDK 了吗？您有 D3D10SDKLayers.DLL 吗？
