How to pass a dynamic array into a VBA object. Compile error: Invalid use of property

Question

I'm trying to pass an array into a custom class for storage and further use within that object. The class object has the following definition:

' Class Name: MBRMCurves
Implements ICurves

Private m_lInterpDates() As Long

Public Property Get InterpDates() As Long()

    InterpDates = m_lInterpDates

End Property

Public Property Let InterpDates(lInterpDates() As Long)

    m_lInterpDates = lInterpDates

End Property

The module that calls this code looks like this:

Dim objResult     As New MBRMCurves

    'Store the forward prices
    Dim fx_fwd()      As Double

    'Store the interpolation dates
    Dim int_dates()   As Long

    'initially there are no people
    Dim NumberTenors  As Integer
    NumberTenors = 0

    Dim cell          As range

    ' Create ranges of Dates
    Dim range     As range
    Dim range_topcell As range

    ' TODO Pri1 Create the Curves Obj
    With Worksheets("test")

        ' Populate the dates of the FWD rates.
        Set range_topcell = .range("B5")
Debug.Print range_topcell.Value
        Set range = .range(range_topcell, range_topcell.End(xlDown))
Debug.Print range.Count

        ' Add more columns to the FWD array
        ReDim fx_fwd(0 To range.Count - 1, 0 To 3)
        ReDim int_dates(0 To range.Count - 1)

        ' Set the counter
        NumberTenors = 0

        ' Populate the dates of the FWD rates into the first column of the dates array.
        For Each cell In range
            NumberTenors = NumberTenors + 1
            int_dates(NumberTenors - 1) = cell.Value
        Next cell

        ' Add interpolation dates to Curves object
        objResult.InterpDates int_dates

The last line in the above code is giving me the compile error: Invalid use of property.

I believe that the syntax of me Let function is correct, but I might be missing a more subtly nuanced oversight.

Can anyone see what I'm doing wrong? I'm working with Excel 2003 and VBA 6.5 on Windows XP.

Any suggestions would be greatly appreciated.

Thanks,

Answer 1

a property is not a method call and you need to set it equal to your array:

objResult.InterpDates = int_dates

There still might be an issue with the array your passing in but this is a first step.
