Render frame in dual screen (fullscreen mode)

Hello everybody,


I’d like to render frame on D3D9 using two screens in fullscreen mode.
For example :
I have two screens resolution 1024x768.
So I’d like to render frame in 2048 x 768 same time on two screens.
How must I program based on D3D9?

I tried somethings, but I don't find the soluce.

Here is some my code :

[source lang="cpp"]
#define SCREEN_WIDTH 2048
#define SCREEN_HEIGHT 768
[/source]

[source lang="cpp"]
ZeroMemory(&wc, sizeof(WNDCLASSEX));

wc.cbSize = sizeof(WNDCLASSEX);
wc.style = CS_HREDRAW | CS_VREDRAW;
wc.lpfnWndProc = (WNDPROC)WindowProc;
wc.hInstance = hInstance;
wc.hCursor = LoadCursor(NULL, IDC_ARROW);
wc.lpszClassName = L"WindowClass";

RegisterClassEx(&wc);

hWnd = CreateWindowEx(NULL, L"WindowClass", L"Our Direct3D Program",
WS_EX_TOPMOST | WS_POPUP, 0, 0, SCREEN_WIDTH, SCREEN_HEIGHT,
NULL, NULL, hInstance, NULL);[/source]

[source lang="cpp"]
d3d = Direct3DCreate9(D3D_SDK_VERSION);

D3DPRESENT_PARAMETERS d3dpp;

ZeroMemory(&d3dpp, sizeof(d3dpp));
d3dpp.Windowed = FALSE;
d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD;
d3dpp.hDeviceWindow = hWnd;
d3dpp.BackBufferFormat = D3DFMT_X8R8G8B8;
d3dpp.BackBufferWidth = SCREEN_WIDTH;
d3dpp.BackBufferHeight = SCREEN_HEIGHT;

d3d->CreateDevice(D3DADAPTER_DEFAULT,
D3DDEVTYPE_HAL,
hWnd,
D3DCREATE_SOFTWARE_VERTEXPROCESSING,
&d3dpp,
&d3ddev);[/source]
