I am having issues retrieving a swapchain and device from directx. further info is in the 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

[EDIT]
Prior to Goz response, I checked out further debug detail and this is what was recieved
DXGI Error: IDXGIFactory::CreateSwapChain: SwapEffect is unknown.
which I am guessing I did not add the swapeffect attributes. I will do that and check it out
Silly me. earlier I mentioned in a comment that both books I was reading did not include a swapchain effect property. I knew something was off regardless of if I included the swap chain or not.
But I also notice that both books zeroed out the swap chain description. Making it more safe to leave out properties. So I added the following
SecureZeroMemory(&swapChainDesc, sizeof(swapChainDesc));
and everything worked. Set aside this, I should still add a swapchain effect property. But for reason's the book decided not to, i have not figured out yet.
Try not passing a pointer to your HWND through. You should pass an HWND as a non-pointer. Other than that I don't see anything massively 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 see what the error is?
Btw my working DX10 initialisation is as follows (Warning a LOT of code!):

I hope thats some help!
The following code worked for me (I'm 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, ¤tFeatureLevel, &pContext);
So you can just try adding more attributes to the swapChainDesc.
