Copy array data in a dataset using Range

[norbert.bakkers@lr.org]

I’ve been trying to get data from a simple test array in a dataset using the Range command. Using the ‘Transferring Large Data Sets Section by Section’ example as a guide I made the following procedure:

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

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?

1) At the moment the range method only works if all arguments are defined.
Example:

  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
      .Range(fpDataComponentY, 1, 1, .NumberOfColumns, .NumberOfRows).Value = TmpArr
      .Update
  End With

2) Create a FPScript formula for each dataset and use the index operator.

Sub MatrixToDataSeries()

    Dim oMatrix As DataSet
    Set oMatrix = ThisDatabase.RootFolder.Object("Matrix", fpObjectTypeDataSet)
    Dim oFml As Formula
    For i = 1 To oMatrix.NumberOfColumns
        Set oFml = ThisDatabase.RootFolder.Add("Dataset" & CStr(i), fpObjectTypeFormula)
        With oFml
            .Formula = "Matrix[" & i - 1 & "]"
            .Update
            .Evaluate
        End With
    Next i
End Sub

Thank you for the quick reply.
I wasn’t aware that all components of the Range 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 Range) 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.

Alternatively you have to copy the column values into a new variable.
Example:

  Dim TmpArr(1 To 3, 1 To 2) As Single
   
  TmpArr(1, 1) = 1
  TmpArr(2, 1) = 2
  TmpArr(3, 1) = 3
  TmpArr(1, 2) = 4
  TmpArr(2, 2) = 5
  TmpArr(3, 2) = 6
 

  ReDim TmpArr2(LBound(TmpArr, 2) To UBound(TmpArr, 2)) As Single
  
  For i = LBound(TmpArr) To UBound(TmpArr)
    For j = LBound(TmpArr2) To UBound(TmpArr2)
        TmpArr2(j) = TmpArr(i, j)
    Next j
    
    ' Create DataSet
    
  Next i
