Hi.
I thought that supplying a runnable script that only needed a missing bit added
at an identified point would be most helpful way to ask about this subject.
However, since no one has even so much as said "Yes, that can be done.", I'm
starting to wonder if it can be done at all, and I'm also wondering if
supplying a script made my question seem more complicated to read and reply to
than intended.
So, script aside, I will try to re-ask this question in the simplest form I can
come up with:
Is it possible using the AB object model to:
a. Open AB, open a chart, apply an AFL, SEE THE CHART WITH YOUR AFL APPLIED,
then dismiss and quit.
or
b. Open AB, load a template, SEE THE TEMPLATE DISPLAYED, then dismiss and
quit.
Responses that would be helpful to me at this point include:
1. I wanted to do that too, but I wasn't able to make it happen. :-(
2. I've done that. It can be done. Keep at it. Good luck! :-P
3. I've done that, here's how ... :-)
4. Are you blind? Exactly how to do it (with a working example!) is right
here in the docs:< link> :-[
Load, display, dismiss - that should be all I need ...
