What interface are you talking about? How can I cast to something I don't have? I do not have a photoshop COM interface. Are you saying that if CoCreateInstance worked that I can then use the iid or pUnk to access the COM? Do I get the members by trial and error? pUnk.width? Even if CoCreateInstance passed, what do I do next?
You have to define the interface yourself, extending from IUnknown, implementing whatever functions are available on the COM interface you want. Here's an example for the ID3D11Device interface:
