Extracting 3 Arrays from 1 Array

[JingleRock]

I have a 2-dimensional array [vtData(0, 0)] that is Dimensioned (Dim
vtData As Variant); its Lbound for each dimension is 0 and its UBound
for dimension1 is 4 and its UBound for dimension2 is 2; therefore, 15
elements. (This array is imported into my VBA Code from Bloomberg.)

I do NOT want to paste this array into a worksheet; however, in design
mode only, I am using the following to do exactly that (and it works):

ActiveSheet.Range(Cells(8, 1), Cells(8 + UB1, 3)) = vtData(0, 0),
where UB1 is UBound for dimension1.

OK, I want to create 3 child arrays (one for each column) from the
parent array. (My objective is to connect the individual elements for
each column into one string, using a delimiter, and then paste that
string into a specified cell in my worksheet.) This is my non-working
code:

Dim Col_One As Variant, x As Integer
ReDim Col_One(UB1 + 1)
For x = 0 To UB1
Col_One(x) = vtData(x, 0)
Next x
When stepping-thru my code:
when x = 0, there are no errors;
when x = 1, I get the dreaded 'subscript out of range' error.

Do I need to use WorksheetFunction.Transpose?

Col_One = Application.Index(vtData, 1)
Col_Two = Application.Index(vtData, 2)
Col_Three = Application.Index(vtData, 3)

Bob,

Thanks for your response.
I changed the name of my "child" array to 'Col_Array', since I am
using it for each of the 3 columns.
I got the following to work:

Dim Col_Array As Variant, x As Integer
ReDim Col_Array(UB1 + 1)
For x = 0 To UB1 '= 4
'THIS IS FIRST COLUMN
Col_Array(x) = vtData(0, 0)(x, 0)
Next x

Any comments?

 

[p45cal]

Have a look at and try out the following (comments in the code:

Sub blah()
'try this with a clean sheet active:
'set up vtData as you describe
Dim vtData(0 To 4, 0 To 2) As Variant
i = 1
For xx = 0 To 4
For yy = 0 To 2
vtData(xx, yy) = i
i = i + 1
Next: Next

UB1 = 4 ' you said 4 was UBound of dim1
Range("A1:C5") = vtData 'just to visualise although I tried your line too:
ActiveSheet.Range(Cells(8, 1), Cells(8 + UB1, 3)) = vtData(0, 0) 'and got
all 15 cells the same
Dim Col_One As Variant, x As Integer
ReDim Col_One(UB1 + 1)
For x = 0 To UB1
Col_One(x) = vtData(x, 0) 'this loop went through without any error
Next x
'however you may find this bit useful:
Col1 = Application.Transpose(Application.Index(vtData, 0, 1))
Col2 = Application.Transpose(Application.Index(vtData, 0, 2))
Col3 = Application.Transpose(Application.Index(vtData, 0, 3))
'Col1 above is VERY similar to your Col_One

'but to get things into strings you may not need to use child arrays:
For y = 0 To 2
For x = 0 To 4
Select Case y
Case 0
ArCol1 = ArCol1 & vtData(x, y) & ","
Case 1
Arcol2 = Arcol2 & vtData(x, y) & ","
Case 2
Arcol3 = Arcol3 & vtData(x, y) & ","
End Select
Next: Next
'now ArCol1 contains a string similar to what I think you want
Stop 'comment out after examiningthe Locals window
End Sub

I want to create 3 child arrays (one for each column)

Do I need to use WorksheetFunction.Transpose?

Hi. In "general", one way is to use Transpose.
Any ideas here that can help?

Sub Demo()
Dim m As Variant 'Matrix
Dim v As Variant 'Vector
Dim s As String 'String
Dim c As Long 'Column
Const All As Long = 0 'All Rows or Columns

m = [A1:C5].Value
With WorksheetFunction
For c = 1 To 3
v = .Index(m, All, c)
v = .Transpose(v)
s = Join(v, ",")
Debug.Print s
Next c
End With
End Sub

ActiveSheet.Range(Cells(8, 1), Cells(8 + UB1, 3)) = vtData(0, 0),

I like to use "Resize," as I find it easier to read / understand.

Sub Demo2()
Dim m As Variant 'Matrix
m = [A1:C5].Value

[A10].Resize(5, 3) = m
End Sub

Thanks Bob, again, p45cal, and Dana. I learned a lot from your posts.

Re: my application -- I am hereby providing add'l info. I was using
static arrays at first, but I now (with the benefit of what I have
learned) must use dynamic ones (actually, the number of columns is a
constant) as my application requires.

I posted (most of) the code below in Msg #3; I am flabbergasted that
this works. Can anyone explain why?

Dim vtData As Variant
Dim Col_Array As Variant, x As Integer, UB1 As Integer
vtData = Bloomberg download code (imports variable # of rows, 3
columns)
're: above data -- Col 1 is all dates; Col 2 is all prices;
Col 3 is all $ amounts
UB1 = UBound(vtData(0, 0), 1)
ReDim Col_Array(UB1 + 1)
For x = 0 To UB1
'THIS IS FIRST COLUMN (with Dimension2 Index = 0)
Col_Array(x) = vtData(0, 0)(x, 0)
Next x

I am using the same ReDim stmt and the same Col_Array(x) name for Col
2 and for Col 3.

I get errors with the likes of
UBound(vtData(0, 0), 1)
and
vtData(0, 0)(x, 0)

Let's have the code that creates vtData (or vtData(0,0) from Bloomberg.

That is an array of arrays, something like

myArray = Array(Array("A", "B", "C"), _
Array("D", "E", "F"), _
Array("G", "H", "I"))

although these are single dimension arrays
