ReDim Preserve to a Multi-Dimensional Array in Visual Basic 6

Question

I\'m using VB6 and I need to do a ReDim Preserve to a Multi-Dimensional Array:

 Dim n, m As Integer
    n = 1
    m = 0
    Dim arrCity() As String
    ReDi         


        

Answer 1

Function Redim2d(ByRef Mtx As Variant, ByVal QtyColumnToAdd As Integer)
    ReDim Preserve Mtx(LBound(Mtx, 1) To UBound(Mtx, 1), LBound(Mtx, 2) To UBound(Mtx, 2) + QtyColumnToAdd)
End Function

'Main Code
sub Main ()
    Call Redim2d(MtxR8Strat, 1)  'Add one column
end sub

'OR
sub main2()
    QtyColumnToAdd = 1 'Add one column
    ReDim Preserve Mtx(LBound(Mtx, 1) To UBound(Mtx, 1), LBound(Mtx, 2) To UBound(Mtx, 2) + QtyColumnToAdd)
end sub
