Write directly to video memory

[simon]

Hi,

how can I access video memory using managed DirectX?

I have a C++ application that needs to display images very fast. On top
the application is a GUI written in C#. A thin managed C++ layer acts
as an interface between the C++ code and the C# code.

I'd like to copy image data (bitmap) from a hardware device directly to
video memory. I'd like to avoid having to copy the data to RAM in order
to display it. Is there a way to let the C# code pass a pointer to
video memory or a DirectX interface to the C++ code?

TIA
simon
