Excel VBA: Nested Areas in a Range object ?
Posted on 2016-07-20
I am fairly sure this is not possible but I wanted to 'bounce it off' my fellow Excel experts to be sure.
When you have a range object that includes multiple non-contiguous ranges they are represented as child 'Area' objects of a master Range object. If you have multiple ranges which each contain multiple areas and you combine those ranges will you only get one 'level' or area objects or can each area object include multiple areas in a nested fashion ?
It appears to me, and common sense. that when a new range is created out of a union of combined ranges their multi-area reference notation is simply combined together so it appears as if you had selected all the areas in one range object. In which case it is not possible that one of more areas in a range will itself contain multiple areas.
Am I right ?

I think one way to test this is to look at some VBA with a union of some ranges that overlap.
I predefined the ranges.
Dim Area1Rng As Range
Dim Area2Rng As Range
Dim Area3Rng As Range
Dim Area4Rng As Range
Set Area1Rng = Range("Area1")
Set Area2Rng = Range("Area2")
Set Area3Rng = Range("Area3")
Set Area4Rng = Range("Area4")
For Each itm In Area1Rng
lstRangesArea1.AddItem itm.Address
Next
For Each itm In Area2Rng
lstRangesArea2.AddItem itm.Address
Next
For Each itm In Area3Rng
lstRangesArea3.AddItem itm.Address
Next
For Each itm In Area4Rng
lstRangesArea4.AddItem itm.Address
Next
Dim unionRng As Range
Set unionRng = Union(Area1Rng, Area2Rng, Area3Rng, Area4Rng)
For Each itm In unionRng
lstRangesUnion.AddItem itm.Address
Next
I predefined the ranges.
So you're agreeing with me ?
To put another way; is there any way to create a range object where the areas within it themselves have areas ?

I'm trying to understand what the question is.
Maybe an array of ranges like this?
Then if you process each range in the array, that will give you what you want?
notice that the duplicates are not removed when done this way.
Maybe an array of ranges like this?
Dim prog2Rng(3) As Range
Set prog2Rng(0) = Range("Area1")
Set prog2Rng(1) = Range("Area2")
Set prog2Rng(2) = Range("Area3")
Dim i
For i = 0 To UBound(prog2Rng) - 1
For Each itm In prog2Rng(i)
lstRangesTest.AddItem itm.Address
Next
Next
Then if you process each range in the array, that will give you what you want?
notice that the duplicates are not removed when done this way.
That doesn't really answer my question i am afraid.
What I am trying to determine is: Is it possible for the area object of a range to itself contain areas ?
I don't think so but I am looking for other's opinions.

Hi,
When you create a new range by Union of many Ranges, the new range has its own areas, it does not have the memory of past areas( or sub-areas) .
