   COM Component with DirectX
  Ok heres my problemI'm fairly new to DirectX programming i've created an application which renders some terrain using DirectX and C++.NET however what i want to do now is create a component so i can embed it into a windows Form which is allready written in C# i know the .Net environment should allow me to do this fine but i am not sure of the best way to go about this. i can create the user control fine but i don't know how to link my directX device in with what i've produced as i'm new to DirectX. any samples or tutorials anybody could recommend which might help with this would be great or any advice on how to link the directX stuff with the component i'm loading into a C# form. I hope this post makes sense, and any comments are greatly apreciated - i'm sure theres a simple enough answer for how to do this.
