Copy array data in a dataset using Range

I’ve been trying to get data from a simple test array in a dataset using the Range command. Using the [i]’Transferring Large Data Sets Section by Section'[/i] example as a guide I made the following procedure:
[code]
Private Sub CommandButton2_Click()
Dim TmpArr(1 To 3) As Single

TmpArr(1) = 2
TmpArr(2) = 3
TmpArr(3) = 4

With ActiveDatabase.RootFolder.Add(“Signal”, fpObjectTypeDataSet)
.DataStructure = fpDataStructureDataSeries
.DataType(fpDataComponentAll) = fpDataTypeFloat32
.NumberOfRows = 3
.FillColumns “(NumberOfRows(i), FloatingPoint32 0, FloatingPoint32 0)”, fpDataComponentAll
.Update
End With

ActiveDatabase.RootFolder.Object(“Signal”).Range(fpDataComponentAll).Value = TmpArr

End Sub
[/code]
This routing crashes at the Range statement with an ‘Invalid procedure or argument’ error. What am I doing wrong?

Also, if this is all working, I would like to transfer data from a multidimensional array (50 columns) in 50 individual datasets. Is it possible to do this using the Range statement. In other words, how do I select 1 column in the array?

Thank you for the quick reply.
I wasn’t aware that all components of the [b]Range[/b] method had to be specified. Flexpro help (Version 7) has these specified as optional, so I left them out. However, the routine is working fine now, thanks for that.

Regarding the second question:
I didn’t specify this very clear, but the multidimensional matrix is a VBA matrix, not a Flexpro matrix. I am struggling to select individual columns in the VBA matrix.
I can now copy the whole matrix from VBA to a Flexpro DataMatrix (using [b]Range[/b]) and then split them into individual datasets. However, I would prefer to copy the data columns straight from the VBA matrix to the Flexpro datasets.
