ODBC and Visual C++

I am currently writing a front end application is Visual C++ to work with a
Postgres backend. I set the recordset class' m_nDefaultType to dynaset in
the constructor, which should allow me to update the records. I compile the
program, and I get a messagebox telling me that the ODBC driver does not
support dynasets. If I try to do it as a snapshot, then there is no problem,
except that I cannot update. I am using a system DSN, and letting the Visual
C++ wizards generate the recordset/view classes using ODBC. Does anyone know
how I can get the ODBC driver to support dynasets? I'm sure it's really
easy, I just don't know ODBC that well.
