D3D D2D Interop on Windows 7 - c++-cli

Question

I'm trying to use DWrite to draw text in my dx11 app but I'm having lot of problems, I shared resources beetween D3D10 Device and D3D11 Device because dx10 is capable to connect D3D with D2D, that's the code of my GraphicsDevice:

When I call SpriteBatch.DrawString(...) from my C# app I'm not obtaining nothing written on my screen, can please somebody explaining me what's I'm missing? I'm new on DirectX programming so please be quiet with me xD Thanks!

Answer 1

There's a lot of code you posted and I didn't read it all, but I was trying to do the same thing (successfully) a few days ago and I might have some suggestions.
Overall, it looks like you do this more or less the same way I do. What I did different it that I created the shared texture using D3D11 device, but this should make no difference. The second thing, which I think could be the problem, is that you're not synchronizing the texture resource between D3D10 and D3D11.
When I tried to use such resources without synchronization, D2D was only rendering stuff once in like 50 calls, the rest just had no effect. I think I was continously blocking the resource when rendering it with D3D11.
You should create the texture using
tDesc.MiscFlags = D3D10_RESOURCE_MISC_SHARED_KEYEDMUTEX;
instead. Here are the details about this flag: MSDN. Basically, you query two IDXGIKeyedMutex interfaces from the shared texture objects on both D3D10 and D3D11 devices. You lock the D3D10 mutex when you draw your D2D stuff to the texture. You lock the D3D11 mutex when you want to use this texture in D3D11. You do this using IDXGIKeyedMutex::AcquireSync and IDXGIKeyedMutex::ReleaseSync. Just be sure to pass the same Key value to each consecutive D3D10 Release -> D3D11 Acquire and D3D11 Release -> D3D10 Acquire calls.
Oh, one more little, not important thing, I noticed this in your code:
texture->QueryInterface<IDXGISurface>(&dxgiSurface);
dxgiSurface->QueryInterface<IDXGIResource>(&dxgiResource);
I'm not 100% sure, but I think you can get the IDXGIResource interface directly from your texture.
