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 

    ID3D10Texture2D *backBufferSurface;

    DXGI_SWAP_CHAIN_DESC swapChainDesc;
    swapChainDesc.BufferCount = 2;
    swapChainDesc.BufferDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM;
    swapChainDesc.BufferDesc.RefreshRate.Numerator = 60;
    swapChainDesc.BufferDesc.RefreshRate.Denominator = 1;
    swapChainDesc.BufferDesc.Width = width;
    swapChainDesc.BufferDesc.Height = height;
    swapChainDesc.SampleDesc.Count = 1;
    swapChainDesc.SampleDesc.Quality = 0;
    swapChainDesc.OutputWindow = *mainWindow;
    swapChainDesc.Windowed = TRUE;

    D3D10_DRIVER_TYPE driverType = D3D10_DRIVER_TYPE_HARDWARE;

    HRESULT hr = D3D10CreateDeviceAndSwapChain(NULL,driverType,NULL,0,
        D3D10_SDK_VERSION, &swapChainDesc,&swapChain,&dxDevice);

    if(FAILED(hr))//Error is here
        throw GXVideoException(L"Problems retrieving directX device");
}

[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

A: 

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!):

    }

    if ( FAILED( pFactory->MakeWindowAssociation( mInitParams.hWnd, 0 ) ) )

        vAdapters.push_back( pAdapter );
        count++;
    }

    unsigned int selectedAdapter    = mInitParams.display;
    if ( vAdapters.size() > 1 )
    {
        // Need to handle multiple available adapters.
    }

I hope thats some help!

Goz
I will give it a try. but I don't see why I can not pass it as a pointer as long as I pass it by value.
numerical25
That didnt work. besides, I would prefer to pass by pointer because I would like to keep track of only 1 object of the HWND. But I do think I have the debug on. The following is extra errors I recieved"DXGI Error: IDXGIFactory::CreateSwapChain: SwapEffect is unknown." I also updated at the top
numerical25
@numerical25: Well try setting the swap effect. As you have it now it will be set to 0xcc (in debug and something randomly that may or may not work in release) because you don't set it to anything! Btw you wouldn't end up needing to track an HWND any more times by sending it as a plain HWND instead of a pointer. A handle is, broadly, similar to a pointer so you really don't need to worry about things like that.
Goz
I just think its odd that two books that I have do not have the swapeffect property set for their initial directX startup
numerical25
Do they do the following, perchance? "DXGI_SWAP_CHAIN_DESC swapChainDesc = {0};" as this initialises the entire structure to 0.
Goz
Yes, I already caught on to that. They used a securezeromemory.
numerical25
A: 

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.
