PostgreSQL/libpqxx Class Generator

, 18 Aug 2006
Automated generation of PostgreSQL data transfer classes.

/***************************************************************************
 PGWizConnect.h  -  This page gets the database name, user name, password,
                    etc from the user and attempts to connect when the "Next"
					button is clicked.

					Note that the entry fields are automatically stocked with
					the previous execution's entries. It does this because I
					got sick of typing things in.
