ques re help file examples - don't set objs to nothing?

Anonymous — Sat, 17 Feb 2001 11:03:00 GMT

On the subject of setting object variables to nothing when they're no longer
needed, I have looked at many help file code examples on diff subjects and
not found any that follow that rule. Is that intentional to teach us
beginners bad programming manners?

--
related ques: is this a different case?
Function MirrorObjSet(objSet, mirrptarr)

Dim obj1 As AcadEntity

For Each obj1 In objSet
...do something with obj1...
next obj1
end sub

Here, obj1 was never set using the 'Set' command?/keyword?/function?
so does it still need set to nothing at the end or is this different?

Hi Mark. Tis example is indeed a bit different. When using For Next to iterate a set of objects,
the iterator is automatically pointed at the next object in the collection.

So an iterator even tho it points to an object does not need to be set =
nothing
after pointing to the last object in the collection it doesn't remain stuck
there, it goes out of scope automatically like and int or double etc
variable?

That's correct. One thing to keep in mind is that you can't ever go
wrong by setting an object to Nothing so long as it's an object you
created. So even though you don't *have* to clear the iterator object
(or any other object for that matter), it's perfectly ok to do so.
