I am aquiring a handle to a shared resource from one process and wanting to display this same resource in a secondary process.
In the secondary process I get a texture handle to the shared resource:
_d3dDevice->OpenSharedResource( _sharedHandle, __uuidof(ID3D10Texture2D), (LPVOID*) &_sharedTexture );
I then copy this resource to my back buffer, pBuffer:
HRESULT hr = _sharedTexture->QueryInterface( __uuidof( ID3D10Resource ), ( void** )&pSrcResource ); if ( FAILED( hr ) ) return hr; D3D10_TEXTURE2D_DESC desc; ZeroMemory( &desc, sizeof(desc) ); _sharedTexture->GetDesc( &desc ); _d3dDevice->CopySubresourceRegion( pBuffer, 0, 0, 0, 0, pSrcResource, 0, 0 );
What I get is a black square drawn to my window. If I check the D3D10_TEXTURE2D_DESC I can see I have the correct dimensions etc but what appears on the screen seems to be a null texture.
Any ideas where I am going wrong? Is there something I need to do to the shared resource before I call CopySubresourceRegion? Should I be using a different technique to get at the shared resource?
Thanks in advance, Andy
