Class deallocation

Not if you explicitly allocated the memory.

DirectX interfaces are COM objects. You should always call Release() on them.

Am I right in assuming that, for example, if you declared a LPDIRECTX8 object or whatever inside another object, (say class Game) the memory will be free when the encapsulating object''s destructor is called?

No. You must write code to make this happen.
If the object is allocated on the stack, it will be freed automatically. If you use new, you must delete, if you new[] you must delete[], if you create a COM object you must call ->Release()

If you want them to automatically be released, you need to use smart pointers.

#include <ATLBase.h> class MyClass { CComPtr<IDirect3D8> m_spD3D8; HRESULT Init() { if(NULL==(m_spD3D8.p=Direct3DCreate8(D3D_SDK_VERSION))) return(E_FAIL); } };

The CComPtr template will call ->Release when the instance of MyClass is destroyed.
