[MFC] [Direct3D] D3D11CreateDeviceAndSwapChain返回E_INVALIDARG [英] [MFC] [Direct3D] D3D11CreateDeviceAndSwapChain returning E_INVALIDARG

问题描述

我正在尝试编写一个库，为我的应用程序提供Direct3D支持.它们正在扩展DLL中实现，我期望可以从MFC应用程序中调用这些对象/函数.

I'm trying to write a library that provides my Applications with Direct3D support. They're being implemented in an extension DLL and I anticipate the objects/functions being called from MFC applications.

int D3DEngine::initialize(HWND w, HINSTANCE i)
{
	window = w;
	instance = i;
	
	GetClientRect(window, &Location);

	unsigned int width = Location.right - Location.left,
		height = Location.bottom-Location.top;

	D3D_DRIVER_TYPE dTypes[] =
	{
		D3D_DRIVER_TYPE_HARDWARE//, D3D_DRIVER_TYPE_WARP
	};
	int tTypes = ARRAYSIZE(dTypes);
	D3D_FEATURE_LEVEL dLevels[] =
	{
		D3D_FEATURE_LEVEL_11_1, D3D_FEATURE_LEVEL_11_0,
		D3D_FEATURE_LEVEL_10_1, D3D_FEATURE_LEVEL_10_0
	};
	int tLevels = ARRAYSIZE(dLevels);


	DXGI_SWAP_CHAIN_DESC swapChainDescription;
	ZeroMemory(&swapChainDescription, sizeof(DXGI_SWAP_CHAIN_DESC));
	// Initialize the swap cahin
	swapChainDescription.BufferCount = 1;
	swapChainDescription.BufferDesc.Width = Location.right - Location.left;
	swapChainDescription.BufferDesc.Height = Location.bottom - Location.top;
	swapChainDescription.BufferDesc.Format = DXGI_FORMAT_R32G32B32A32_SINT;
	swapChainDescription.BufferDesc.RefreshRate.Numerator = 30;
	swapChainDescription.BufferDesc.RefreshRate.Denominator = 1;
	swapChainDescription.BufferUsage = DXGI_USAGE_RENDER_TARGET_OUTPUT;
	swapChainDescription.OutputWindow = w;
	swapChainDescription.Windowed = true;
	swapChainDescription.SampleDesc.Count = 1;
	swapChainDescription.SampleDesc.Quality = 0;

	unsigned int flags = D3D11_CREATE_DEVICE_BGRA_SUPPORT;

#if _DEBUG
	flags |= D3D11_CREATE_DEVICE_DEBUG;
#endif

	HRESULT results;

	for (int c = 0; c < tTypes; c++)
	{
		
			results = D3D11CreateDeviceAndSwapChain(0, dTypes[c], 0,
				flags, dLevels, tLevels, D3D11_SDK_VERSION,
				&swapChainDescription, &swapper, &graphicsDevice, &version, &contextDevice);


			if(results == E_INVALIDARG)
				results = D3D11CreateDeviceAndSwapChain(0, dTypes[c], 0,
					flags, &dLevels[1], tLevels-1, D3D11_SDK_VERSION,
					&swapChainDescription, &swapper, &graphicsDevice, &version, &contextDevice);
			if (SUCCEEDED(results))
			{
				driver = dTypes[c];
				goto exitLoop;
			}
		//WCHAR* errorDesc = 
	}

exitLoop:

	if (FAILED(results))
	{
		return NO_DEVICE;
	}

	ID3D11Texture2D* texture;

	results = swapper->GetBuffer(0, __uuidof(ID3D11Texture2D), (LPVOID*)&texture);
	if (FAILED(results))
	{
		return NO_SWAP_CHAIN;
	}
	results = graphicsDevice->CreateRenderTargetView(texture, 0, &renderTarget);

	if (texture)
		texture->Release();

	if (FAILED(results))
	{
		return NO_RENDER_TARGET;
	}

	contextDevice->OMSetRenderTargets(1, &renderTarget, 0);

	// Create Swap Chain

	isInit = true;
	return NO_ERROR;
}

两次调用函数的想法来自这篇文章:

The idea of calling the function twice came from this article:

文档中提供的关于E_INVALIDARG可能来自何处的唯一其他情况是，当第一个参数是与HARDWARE设备组合在一起的非NULL值时.但是，这不是我在这里所做的.

The only other circumstance the documentation provides regarding where the E_INVALIDARG might come from is when the first parameter is a non-NULL value combined with a HARDWARE device. However, that is not what I'm doing here.

是否有办法弄清楚为什么我会收到此错误?

Is there a way to figure out why I'm getting this error?

我确实看到场景与Direct2D(可能已初始化其渲染目标)以及媒体基础一起使用.

I do see the scene being used in conjunction with Direct2D (the render target of which might have already been initialized), and possibly with the media foundation.
