February
User Meeting
February was one of those bonanza months for FoxPro folks, with opportunities to hear several leaders of our nationwide community right here in LA. Bill House of Flash Creative Management leac off the meeting with a discussion of Object Onented Programming in FoxPro. The slides and ideas were based on his similar presentation at thE last FoxPro Developers Conference. He was not positioning FoxPro as an object oriented language but rather was showing how you could implement several aspects of an object oriented design using the existing FoxPro language. His recommendation was to start thinking this way now to be ready to take advantage of the richer object oriented capability in FoxPro 3.
I will have copies of his paper at the user meeting, but here are a few of the ideas
-
compared to our usual programming solutions, an OOP solution looks more like the problem as perceived by the user
-
that is, the program model is closer to the real world and is thus hopefully a better model that is easier to understand, implement, and evolve:
1. The design focus is on entities rather than our usual emphasis on process and procedure.
2. Objects are self contained with a well defined interface and interact only by means of messages.
3. Objects contain code and data with external access to the data accomplished indirectly via a message that invokes an internal method.
4. Change can be managed more easily since implementation details are hidden behind the object interface, so the implementation can change without requiring changes to all interacting elements.

LAST
MEETING
Bruce Braunstein came, as promised. Every one learned something new (even Chuck Williams!) and was impressed with Bruce’s on disk FoxPro magazine, FoxMasters. Bruce also shared some interesting third party goodies and a graphical presentation written by Pat Adams on FoxPro configuration.
NEXT MEETING
We will be taking a cursory look at PowerBuilder, what it is, what it does and the line-up of PowerBuilder products. There is a new product in the PowerSoft lineup (PowerBuilder Desktop) that has been build as a FoxPro Killer so every FoxPro aficianado should have some interest in this subject.
We will also be looking at Gladiator, a FoxPro to C translator that allows a FoxPro developer to write small, fast exe’s.
I thought the following messages might be interesting to FoxPro developers and anyone with an investment in Xbase products. As usual, the>> symbols mean a piece of the previous message from the person being addressed.
THE FUTURE OF FOXPRO

Chuck,
>>>l heard a rumour MSFT is abandoning NT. Not likely, as they are using it to replace
LAN
MANAGER. It is a vital part of MSFT’s long range strategic plans. As for NT version of software, I suspect that it won’t matter as 32 bit Windows apps will probably run on both NT and Chicago (Windows 4.0).
