I think you are right. I am better off using Managed C++. But then goes
another question. Lets say I am wrapping ISomeInterface and want my
wrapper to look something like this:
public __gc class SomeInterface
{
........
private:
CComPtr<ISomeInterface> m_someInterface; // <--- not allowed
}
How do I make this work?
