I share RenderTarget Texture from DX10.1 to DX9Ex to draw it in WPF.

Everithing works perfectly on Windows 7 + GeForce GTS450/GTS560(and many other configurations). But on Windows Server 2008 + Nvidia NVS 300 I got an "An invalid parameter was passed to the returning function" exception in line:

sharedTexture = new Texture(D3DDevice, Texture.Description.Width, Texture.Description.Height, 1, 
                 Usage.RenderTarget, format, Pool.Default, ref handle);

if I remove last parameter "ref handle" - no exception and everthing is running(but with blank screen). Latest drivers, SlimDX and DirectX are installed. Nvidia NVS 300 supports DirectX 10.1.

 

 

D3D10.1 device initialization:

device = new Device(DriverType.Hardware, DeviceCreationFlags.BgraSupport , FeatureLevel.Level_10_1);

D3D10.1 shared texture initialization:

var renderTexDescShared = new Texture2DDescription()
{
      BindFlags = BindFlags.RenderTarget | BindFlags.ShaderResource,
      Format = Format.B8G8R8A8_UNorm,
      Width = windowWidth,
      Height = windowHeight,
      MipLevels = 1,
      SampleDescription = new SampleDescription(1, 0),
      Usage = ResourceUsage.Default,
      OptionFlags = ResourceOptionFlags.Shared,
      CpuAccessFlags = CpuAccessFlags.None,
      ArraySize = 1
};
SharedTexture = new Texture2D(device, renderTexDescShared);

D3D9Ex device initialization:

D3DContext = new Direct3DEx();

PresentParameters presentparams = new PresentParameters();
presentparams.Windowed = true;
presentparams.SwapEffect = SwapEffect.Copy;
presentparams.DeviceWindowHandle = GetDesktopWindow();
presentparams.PresentationInterval = PresentInterval.Immediate;

D3DDevice = new DeviceEx(D3DContext, 0, DeviceType.Hardware, IntPtr.Zero, 
      CreateFlags.HardwareVertexProcessing | CreateFlags.Multithreaded | CreateFlags.FpuPreserve, 
      presentparams);

D3D9Ex texture:

SlimDX.DXGI.Resource resource = new SlimDX.DXGI.Resource(SharedTexture);
IntPtr handle = resource.SharedHandle;
sharedTexture = new Texture(D3DDevice, Texture.Description.Width, Texture.Description.Height, 1, 
                Usage.RenderTarget, format, Pool.Default, ref handle);
