Hey Dan,
I would think that "harder to maintain" is very subjective as I find
them much much much easier to maintain than PRGs.
Do you have some statistics to backup your assertion that running an SCX
is slower than a PRG (I have no doubt it is, but I'd like to see by how
much).
Hi, Frank
One of the members of our San Diego FoxPro group had a giant
configuration dialog with at least 50 (and probably more) controls on
it, that he converted from SCX to code, then did timing tests. It was
quite a while ago (probably around VFP7 time), but as I recall he found
that the code took at most 1/3 of the time the scx did to instantiate
the form. Don't forget, when you call an scx you're reading a database
while you're executing the methods for each control. That introduces a
whole lot of IO delays into the process.
Without doubt I'm prejudiced in favor of code. After all, I'm a
programmer, and I like to program. I certainly find the form designer
useful and convenient for adjusting the layout and appearance, but for
execution and, yes, maintenance I much prefer code. In my experience
most "maintenance" on a form involves changing what happens in the
methods, and I find that a lot easier when I can see them all at once.
Thanks for asking. <g>
Dan
