Direct3DCreate9Ex

[David]

According to Direct3D Document, Direct3DCreate9Ex is in D3D9.DLL. But I find
no exported this function any Direct 3D DLLs.
So the question is how to make a call to create an IDirect3D9Ex interface?

Searching on Google Groups, I found this from Chuck:

"Note that the Direct3D9Ex interface is currently only exposed through the
Windows SDK, not the DirectX SDK." So it's unlikely that this is in
D3D9.dll. Where did you read that?

Are you using Windows XP? The Direct3D9Ex export is only available on
Windows Vista, Windows Sever 2008, and later versions of Windows.

If your application is built for Windows XP and Windows Vista/Server, you
should use explicit linking to call Direct3DCreate9Ex so you can handle the
case of it not being present. The function itself will fail to create an
object if you are running an XPDM driver on Windows Vista/Server 2008 since
Direct3D9Ex requires a WDDM driver.

The sample code in the doc page doesn't make it clear that it only runs on
Windows Vista/Server 2008. I've filed a doc bug. A better sample would be:

IDirect3D9Ex *g_pD3D = NULL;

HMODULE h = LoadLibrary( L"d3d9.dll" );
if ( h )
{
typedef HRESULT (WINAPI *LPDIRECT3DCREATE9EX)( UINT,
IDirect3D9Ex**);

LPDIRECT3DCREATE9EX func = (LPDIRECT3DCREATE9EX)GetProcAddress( h,
"Direct3DCreate9Ex" );

if ( func )
{
if ( FAILED( func( D3D_SDK_VERSION, &g_pD3D ) ) )
{
FreeLibrary(h);
return E_FAIL;
}
}

FreeLibrary( h );

I couldn't find any references to the D3D9.dll requirement using the MSDN
search for IDirect3D9Ex (thus my original response). One thing I dislike
about the docs is that they do not list the required dlls/libs to use a
function/class/interface. Feedback given by many of us to the MSDN docs
team at several MVP Summits. UN*X based programming docs have included
this information since at least the early 80s when I started using it.
