I am learning DirectX from a book. I am getting an error on the code. Here is all mof

I get an error on the "," after the NULL in the block of code at the end. It says "Expected a ')'". Here are my build errors:

Please help.

The book I am using does not talk about headers and libraries. But I was able to fix 2 errors by including your suggested header. I was able to fix another by turning off Intellisense errors. Although my book does not talk about headers and libraries, it does come with a CD containing examples. I found that I should be doing something like this

 HRESULT hr = D3D10CreateDeviceAndSwapChain ( NULL,
		D3D10_DRIVER_TYPE_REFERENCE,
		NULL,
		0,
		D3D10_SDK_VERSION,
		&swapChainDesc,
		&pSwapChain,
		&pD3DDevice);

instead of

HRESULT D3D10CreateDeviceAndSwapChain ( NULL,
		D3D10_DRIVER_TYPE_REFERENCE,
		NULL,
		0,
		D3D10_SDK_VERSION,
		&swapChainDesc,
		&swapChain,
		&pD3DDevice);
 

Thanks for your help.

Now I have another problem. I added this bit of code:

ID3D10Texture2D *pBackBuffer;
	 HRESULT hr2 = pSwapChain->GetBuffer(0,__uuidof(ID3D10Texture2D), (LPVOID*)
	 &pBackBuffer);
	 if (hr2 != S_OK)
	 {

		 return false;

	 }

	 hr2 = pD3DDevice->CreateRenderTargetView(pBackBuffer, NULL,
	&pRenderTargetView);

	 pBackBuffer->Release();

	 if (hr2 != S_OK)
	 {

		 return false;

	 }

	 pD3DDevice->OMSetRenderTargets(1, &pRenderTargetView, NULL);

	 D3D10_VIEWPORT viewPort;
	 viewPort.Width = width;
	 viewPort.Height = height;
	 viewPort.MinDepth = 0.0f;
	 viewPort.MaxDepth = 1.0f;
	 viewPort.TopLeftX = 0;
	 viewPort.TopLeftY = 0;

	 pD3DDevice->RSSetViewports(1, &viewPort);

	 pD3DDevice->ClearRenderTargetView(pRenderTargetView, D3DXCOLOR(0.0f, 0.0f, 0.0f, 0.0f));

My D3DXCOLOR gets an error saying "D3DXCOLOR is undefined." My build errors are as follows:

Error	1	error C3861: 'D3DXCOLOR': identifier not found	c:\users\michael\documents\visual studio 2012\projects\directx\winmain.cpp	184	1	DirectX
	2	IntelliSense: identifier "D3DXCOLOR" is undefined	c:\Users\Michael\Documents\Visual Studio 2012\Projects\DirectX\winmain.cpp	184	56	DirectX

What now?

Yes, here. I found an outdated header for DX9. Do you know why it isn't working?

I did some even further research and found out that D3DXCOLOR is no longer supported. Why, I am not sure. I was able to use a float instead and it now works.
