The destructor will be called only when it goes out of scope.  What I 
want to do is create a ClassB object with a pointer to an already-
existing ClassA object.

Actually, constructing an object without passing a parameter will be an 
error.  I guess I should have included an "assert()" but I really think 
that there's got to be a gentler way out of the situation.

I've got a CDatabase class, used for reading, editing and deleting data 
a row at a time.  I wish to also have a CLink_List class which will 
create linked lists of data from selected columns of ALL rows (used 
solely for display).  I'm not doing this because I'm sure it's the best 
way but rather as an experiment ... because I CAN do it this way.

Can you think of another, possibly better way to do this?
