Apologies for the silly question but I presume vector.erase will call
dtor of the contained objects?
That is correct. How does it help you? Your MyStruct has no d-tor,
and the one that the compiler creates for you won't deallocate your
BSTR members using whatever functions you need.
If not I may not be able to use this
because the vector undergoes erasure/insertion during the lifetime of
my application and during such erasure I want to be able to free up
the BSTRs memory allocated inside every instance of MyStruct. IOW I
have engineered a situation where the capacity of the vector remains
intact -- its just its size() that contracts & expands.
The bottom line: if you have resource acquisition/dismissal during
exectuion of your program, you need to leave it to creation/destruction
of objects. RAII is one of the cornerstones of proper OOP.
As to COM implications, please ask in a Microsoft newsgroup. I am not
certain what you can or cannot do, and this is not the right place to
discsuss it.
