CreateDevice not working for me. I need some enlightened information.
Author
Can anyone fill me in on what effects hardware can have on the call to ''CreateDevice''. I am at my whits end trying to get just a basic red pixel to display. I have even tried to run the example that comes with DirectX 8.0 SDK package in \mssdk\samples\Multimedia\Direct3D\Tutorials\Tut01_CreateDevice. The tutorial doesn''t work for me either. I''m to the point where I think it must be hardware related. Can anyone out there shed any light on where I should look.
thanks in advance,

What kind of video card do you have?
You need to have a driver installed that supports Dx6 or later to use Dx8, IIRC.
Many of the examples require 3D accel cards.

If you can create a Direct3D8 object, call GetDeviceCaps and/or GetAdapterDisplayMode to retrieve information on the specified adapter and its current configuration. Note that, and then try creating a device with that info.

How old is your video hw? Some of the ancient boards out there do not support d3d8 in hw (I had that same problem recently with a virge/gx2 chipset). You may have to stick with sw only rendering (use the D3DDEVTYPE_REF flag). Run dxcapsviewer app and see if the parameters you passed to CreateDevice are compatible w/ the caps given.
If your initialisation code looks something like this, and it doesn''t work, you have a problem 
People might not remember what you said, or what you did, but they will always remember how you made them feel.
// Create the D3D Object if( NULL == ( m_pD3D = Direct3DCreate8( D3D_SDK_VERSION ) ) ) { throw CHException( _T( "Failed to create D3D Object" ) ); } // Retrieve the primary adapter''s current settings D3DDISPLAYMODE d3ddm; m_pD3D->GetAdapterDisplayMode( D3DADAPTER_DEFAULT, &d3ddm ); D3DPRESENT_PARAMETERS d3dpp; ZeroMemory( &d3dpp, sizeof(d3dpp) ); d3dpp.Windowed = TRUE; d3dpp.SwapEffect = D3DSWAPEFFECT_COPY; d3dpp.BackBufferFormat = d3ddm.Format; // Attempt to create a device using the current settings HRESULT hr = m_pD3D->CreateDevice( D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, m_hWnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING, &d3dpp, &m_pD3DDevice ); if( FAILED( hr ) ) { CHException e; e.ParseD3DError( hr ); throw e; } People might not remember what you said, or what you did, but they will always remember how you made them feel.
You might try changing the device type to reference or hardware emulation... if after that it still doesn''t work, it''s probably a hardware/driver problem.

Thanks everyone for the responses. I am running a Voodoo3 3000 with Win2k and DirectX 8.0. I am currently looking to download the latest drivers out there. Hopefully they will help. Has anyone else run across this issue with the hardware/software set I explained above. I would be very interested in a solution that doesn''t require a new computer.
Thanks again everyone!!!!
