The LA Fox Developer
A Newsletter for FoxPro Application Developers in Southern California September 1995
LA Fox President’s Column
by Chuck Williams

At the August meeting we reverted to the format of
many of last years meetings, where members
describe their own FoxPro applications. Bill Ander-
son and I gave a short description of the FoxPro
Mac application we are working on for Stanford
University. I lead off with a discussion about
requirements definition and testing, Bill gave a
demo of the running app showing menus, naviga-
tion, screen design, and report design, and we
followed with a question and answer session.

This a registration system that manages enroll-

supports publication of course catalogs and broad-

and exports data to a Great Plains Dynamics
accounting system for custom invoice processing.

We showed samples of the diagramming tech-
niques used for reaching agreement with users
about requirements, and for documenting our
solution. Process diagrams show how data flows

and reports to show the dialog a user could follow

ing to us about designing and building Class libraries in

October 16, 1995, 7:30 PM - Savannah Brentnall.
Savannah Brentnall is an independent consultant
specializing in object orientation and is a founding
partner of the Visual Training Group, which specializes
in object technology training. Savannah and her
company have recently joined forces with Flash Cre-
ative Management to offer VTG’s two-day course on
object orientation to FoxPro audiences. She has
spoken at conferences and user groups around the
world and has programmed in Xbase since 1984.

It is only fitting that Savannah is speaking at Octo-
ber's meeting. It was just about two years ago, come
October, that she spoke on object orientation, at an LA
Fox meeting, and everyone thought, “Well, that’s nice
and everything, but how does it apply to me?” My,
how times have changed!
