Ah that is nice, you just don't need the set messages. :)
I always looked at the iem gui objects as more sophisticated and better for GUI front ends, not meant for writing a self-documenting patch. They save time and look/act better, but everyone I have met using pd for educational purposes uses the more simple numberbox.

I attached a modified version of your patch to show what I mean. On the right, you can look at the patch and figure out the behavior before you scroll the gatom box (important if you want to make sure you're avoiding a buffer overflow).
On the left, you have to read the source code for those GUI objects to figure out what's going to happen. Judging from your original patch, I think you assumed that sending a float straight to the [nbx] would update the value in the slider (so did I). This turns out not to be the case: the two GUIs are only bound together if you change the values on one of them using the mouse.
If someone who reads and understands c better than me can explain why the iemgui magic works as it does, I'll be happy to document it.

This seems trivial but I've never managed to
figure
out how to do it in
a non-trivial way:
Have a number (atom) and a slider (be it
horizontal or
vertical) which
are 'synced', that is if one changes the
number the
slider changes and
vice-versa.
if you use numberbox2 as the numberbox, you can give
both
the nbx and
the slider the same send/receive names
(that is:
numberbox2.sendname=numberbox2.receivename=slider.sendname=slider.receivename)
and they will be magically linked to each other.
to use the value in the patch add another receiver
[r <samereceivename>]
Except if you need to send a value to the inlet of the numbox2 or the slider. Then this method magically doesn't work, whereas the [set $1(
idiom does.
