Hi James,

This is not my area of expertise, so you'll likely get a much more
definitive answer to this question in the microsoft.public.vc.language
newsgroup, but my impression is that whomever created the SAFEARRAY is
responsible for freeing it.

Hi,

I have a VC++ DLL function which is returning a variant to VBA. The
variant contains a SAFEARRAY (by ref) allocated by the function which
may in turn contain other variants etc. All this being allocated with
CoTaskMemAlloc..

It works fine, except it looks to me like VBA doesn't deallocate the
structures it's getting back when it's finished with them. I've seen
some rumours about IDL's and [in] [out] parameters being the way to do
this, anyone got any ideas?

James
