[AccessD] Log Class part 1B

John,

<<Write once, use forever, you applications become consistent throughout

EXTREMELY powerful).  But it is not the application providing the power, it
is your framework.>>

  Yeah it sounds good, but you haven't told them about the problem with
composite classes<g>.  This is where OOP just falls flat on it's face.

   After programming with VFP for a few years, I realized I basically had
the same problems as before except that things were a heck of a lot more
complex to figure out.

  Up to that point, I had developed methods (calling standard procedures and
changing code on the fly) to work in non-OOP  languages that gave me the
ability to do things like you are discussing.

  The promise of OOP is that you define it once and it works everywhere.
But when you start getting into composite classes, you find once again that
you have the same code in a lot of different places and are almost back to
square one.  Also with OOP you spend a lot of time figuring out the state of
things because you don't know what other routines may have done.  Since your
not supposed to look inside the box, you can never be sure of anything when
your within an object.  It also requires heavy time up front to properly
develop your classes and interfaces and the class hierarchy.  Screw up with
those and you'll be rewriting a lot.

  OOP does have it's place and it can be powerful and flexible, but you need
to go into it with your eyes open.  It's not the pancrea for programming
problems that everyone believes.  Think about how long OOP has been around;
why is there not more of it?  If it was really that great it should have
flooded the development community by now, yet here we are almost 30 years
later still using non-OOP languages.

  I think there is nothing wrong with using objects simply as a means of
simplifying data structures, but using an object orientated language is not
all it's cracked up to be.

Jim.

Yes!  Maybe.  If you are talking about a callback function then the answer
is "damned tough".  However for objects like forms and controls....
