Hi Jase

Thanks for getting back so promptly. I do realise that m_pSet and m_Name are
two different entities i.e. a pointer and variable. As I mentioned in my
last email, I have resolved the problem because it turns out to be that
things have to be done in a different way depending on the version of VC++
being used. However, and because I appreciate that I haven't explained
things fully, others may be interested in seeing the following site:

http://www.mindcracker.com/mindcracker/c_cafe/dao/add_dao_support.asp

At the end of the document there is a graphic which shows the user selecting
the "member variable name" (this is how Microsoft have named the dialog
box - but I understand it is misleading) of m_pSet->m_Search (in this
example). This is written in VC++ 6. My problem occurred because in VC++ 4
you were allowed to enter, manually, "m_pSet->Name" i.e. not from a combo
box, and as we see in VC++ 6 you select "it" from a list BUT in VC++ you
can't enter it manually or select "it" from a list but rather you do it
manually in the member DoDataExchange and, if necessary, use the "auto
complete combo box" which appears during typing "->" to select the
appropriate variable.

Thanks again for all your help.
