Copying whole array in a column in single command

  Asked By: Pedro    Date: Oct 18    Category: MS Office    Views: 1796

Q1: I have an array b in VBA with 10000 elements. I need to write it in
column A of worksheet (cells(1,1) to cells(10000,1)).
By writing element by element, it takes lot of computational time.
for i=1 to 10000

Is there a command which can enable writing the whole 10000 element
array in column A, 10000 rows directly like
Range(cells(1,1),cells(10000,1))=b or something like that.

Range(Cells(1, 1),Cells(1 + uBound(Array), 1)).Value = Array

This is an edited piece of code from a module I use within Access to
export recordset information to Excel. I haven't tested it directly in
Excel, but it should put you on the right path.

Thanks for your help. I can now copy array  b data in excel sheet

How do I copy this excel 10000 cells data back to array c in a
single command.

I'm 95% sure you can't. Use a loop (it'll be a lot faster than writing
to a sheet from an array  with a loop).

You can't copy it into a defined array  item, but if you say:

Dim vData as Variant
vData = ActiveSheet.Range(Cells(1, 1), Cells(10000, 1))

...VBA will create vData as an array like:

vData(1 to 10000, 1 to 1) as Variant

...and if you later say:

vData = ActiveSheet.Range(Cells(1, 1), Cells(10, 1))

...VBA will automatically redimension it as:

vData(1 to 10, 1 to 1) as Variant
