Use findnext to fill multidimensional array VBA Excel

Question

My question actually concerns a matter that extends on EXCEL VBA Store search results in an array?

Here Andreas tried to search through a column and save hits to an array. I am trying the same. But differing in that on (1) finding a value (2) I want to copy different value types from (3) cells in the same row as where the searched value was found, (4) to a two dimensional array.

So the array would (conceptually) look something like:

Searchresult.1st SameRow.Cell1.Value1 SameRow.Cell2.Value2 SameRow.Cell3.Value3
Searchresult.2nd SameRow.Cell1.Value1 SameRow.Cell2.Value2 SameRow.Cell3.Value3
Searchresult.3rd SameRow.Cell1.Value1 SameRow.Cell2.Value2 SameRow.Cell3.Value3

Etc.

The code I use looks like this:

Sub fillArray()

Dim i As Integer
Dim aCell, bCell As Range
Dim arr As Variant

i = 0 

Set aCell = Sheets("Log").UsedRange.Find(What:=("string"), _
                    LookIn:=xlValues, _
                    LookAt:=xlWhole, _
                    SearchOrder:=xlByRows, _
                    SearchDirection:=xlNext, _
                    MatchCase:=False, _
                    SearchFormat:=False)

If Not aCell Is Nothing Then
    Set bCell = aCell
    ReDim Preserve arr(i, 5)
    arr(i, 0) = True 'Boolean
    arr(i, 1) = aCell.Value 'String
    arr(i, 2) = aCell.Cells.Offset(0, 1).Value 
    arr(i, 3) = aCell.Cells.Offset(0, 3).Value
    arr(i, 4) = aCell.Cells.Offset(0, 4).Value
    arr(i, 5) = Year(aCell.Cells.Offset(0, 3).Value)

    i = i + 1

    Do While exitLoop = False
            Set aCell = Sheets("Log").UsedRange.FindNext(after:=aCell)

            If Not aCell Is Nothing Then
                If aCell.Address = bCell.Address Then Exit Do
                'ReDim Preserve arrSwUb(i, 5)
                    arr(i, 0) = True
                    arr(i, 1) = aCell.Value
                    arr(i, 2) = aCell.Cells.Offset(0, 1).Value
                    arr(i, 3) = aCell.Cells.Offset(0, 3).Value
                    arr(i, 4) = aCell.Cells.Offset(0, 4).Value
                    arr(i, 5) = Year(aCell.Cells.Offset(0, 3).Value)

                    i = i + 1
            Else
                exitLoop = True
            End If
    Loop


End If

End Sub

It seems to go wrong on redimming the array in the loop. I get a Subscript out of range error. I guess I can't redim the array as I'm doing now, but I can't figure out how it is supposed to be done.

I’d be greatful for any clues as to what I’m doing wrong.

ReDim Preserve can only resize the last dimension of your array: http://msdn.microsoft.com/en-us/library/w8k3cys2(v=vs.71).aspx

From the above link:

Preserve

Optional. Keyword used to preserve the data in the existing array when you change the size of only the last dimension.

Edit: That's not enormously helpful, is it. I suggest you transpose your array. Also, those error messages from the array functions are AWFUL.

At the suggestion of Siddarth, try this. Let me know if you have any problems:

Sub fillArray()
    Dim i As Integer
    Dim aCell As Range, bCell As Range
    Dim arr As Variant

    i = 0
    Set aCell = Sheets("Log").UsedRange.Find(What:=("string"), _
                                             LookIn:=xlValues, _
                                             LookAt:=xlWhole, _
                                             SearchOrder:=xlByRows, _
                                             SearchDirection:=xlNext, _
                                             MatchCase:=False, _
                                             SearchFormat:=False)
    If Not aCell Is Nothing Then
        Set bCell = aCell
        ReDim Preserve arr(0 To 5, 0 To i)
        arr(0, i) = True 'Boolean
        arr(1, i) = aCell.Value 'String
        arr(2, i) = aCell.Cells.Offset(0, 1).Value
        arr(3, i) = aCell.Cells.Offset(0, 3).Value
        arr(4, i) = aCell.Cells.Offset(0, 4).Value
        arr(5, i) = Year(aCell.Cells.Offset(0, 3).Value)
        i = i + 1
        Do While exitLoop = False
            Set aCell = Sheets("Log").UsedRange.FindNext(after:=aCell)
            If Not aCell Is Nothing Then
                If aCell.Address = bCell.Address Then Exit Do
                ReDim Preserve arrSwUb(0 To 5, 0 To i)
                arr(0, i) = True
                arr(1, i) = aCell.Value
                arr(2, i) = aCell.Cells.Offset(0, 1).Value
                arr(3, i) = aCell.Cells.Offset(0, 3).Value
                arr(4, i) = aCell.Cells.Offset(0, 4).Value
                arr(5, i) = Year(aCell.Cells.Offset(0, 3).Value)
                i = i + 1
            Else
                exitLoop = True
            End If
        Loop
    End If
End Sub

Note: in the declarations, you had:

Dim aCell, bCell as Range

Which is the same as:

Dim aCell as Variant, bCell as Range

Some test code to demonstrate the above:

Sub testTypes()

    Dim a, b As Integer
    Debug.Print VarType(a)
    Debug.Print VarType(b)

End Sub
