COM Help!
Author
Guys,
Just got to the chapter about COM in ToTWGPG.
I''m so damn confused. What I want to know is this:-
Is there anywhere on-line which explains it well?
How important is it for me to know the ins and outs of how it works at this stage - e.g. Can I come back to it later?
I''m stumped. I have tried re-reading but its not sinking in yet.
Help!
I have not read ToTWGPG so I don''t into what depth it goes with COM.
However, to use DirectX you just need to know how to make use of COM objects - not to create them or use IUnknown interfaces and other seemingly confusing stuff. What you need to know is that you get a COM object in DirectX by calling the appropriate factory function:
mypointer = Direct3DCreate8(...);
and when you are done with the object you call:
mypointer->Release();
or the object you created will never be deleted. And thats it.
However, if you are serious about learning more about COM then I can heartedly recommend the book:
Andrew Troelsen: Developer''s Workshop to COM and ATL 3.0
It introduces COM usage and class definition so everybody can understand it. A truely good book.
