How to assign an array to a range in Excel macro?

Hi,

I tried to assign an array ro a range in Excel macro, but it does not work.

Here is the example

sub fill_range()
dim myArray(1 to 5) as single
dim i as integer
for i=1 to 5
myArray(i)=i
next

sheets("sheet1").activate
range("a1:a5")=myArray
end sub

When the macro is run, the values of cells a1 to a5 are 1 instead of 1 to
5. That is all the cells in the range took the value of myArray(1) instead
correspondent (right) ones.

Any suggestions on solving this problem?

Thanks

Hi, John

The line was not correct,as you said. Because the format of the array is
different from that of the range. I redeclared, according to suggestions
from Dick (see his advice) the array as myArray(5, 1). Now it works.

Yes, you can use loop to assign an array to a range. THis is normally OK, if
you array is not big. If it is big, it will take a long time for the reason
that there are same number of interface change between excel sheet and your
program. Using a single statement will only have one interface exchange and
same you a lot of time and frustrations.

Never mind... I saw Dick's response on ms.public.office.developer.vba. I didn't notice the cross-post!

This will work

Sub test()
Dim strA(5) As String

strA(0) = "A"
strA(1) = "B"
strA(2) = "C"
strA(3) = "D"
strA(4) = "E"

Cells(1, 1).Offset(0, 0).Resize(1, UBound(strA)) = strA
End Sub

I remember seen this solution in a book long back; thought of posting this if in case helps to others

Almost There

You're original post was almost correct.

to use one line to dump an array to a range or vice versa, make sure to use the .value property of the range.

For example:

Use myArray=Range("A1:Z26").Value
Not myArray=Range("A1:Z26")

The same goes for the reverse
Correct
Range("A1:B12").Value=myArray

Incorrect:
Range("A1:B12")=myArray

Copying an Array to a Worksheet Range without looping:

From what I read in the post, yes Dick's solution worked.

Array declaration must be atleast 2-Dim - indicates (Row, Col) ??
If you intend to copy to a multiple column range, you'll need to increment the 2nd dimension.

These work:

Option Base 1
'Single Column Range
Sub Test1()
Dim myArray(5, 1) As Double
Dim i As Integer
For i = 1 To 5
myArray(i, 1) = i / 3
Next
Sheets("sheet1").Activate
Range("a1:a5") = myArray
End Sub


'Multiple Column range
Sub Test2()
Dim myArray(5, 2) As Double
Dim i As Integer
For i = 1 To 5
myArray(i, 1) = i / 3
myArray(i, 2) = i / 10
Next
Sheets("sheet1").Activate
Range("a1:b5") = myArray
End Sub
