[AccessD] Classes, Recordsets, and problems inbetween

Hi Marcus:

Don't you have to class get method to pass a recordset to the class? You
have referenced the ADO?

Yeap

mrst has been declared...

Option Compare Database
Option Explicit

Private mlngInvoiceDetailID As Long
Private mlngInvoiceID As Long
Private mlngOrderDetailID As Long
Private mlngProductID As Long
Private mintShipped As Integer
Private mintCanceled As Integer
Private mintBackOrdered As Integer
Private mcurExtendedPrice As Currency
Private mflgSubstituteFlag As Boolean
Private mdteDateAdded As Date
Private mdteLastUpdated As Date
Private mflgActiveFlag As Boolean

Private mrst As ADODB.Recordset  <- Here
Private mflgAddFlag As Boolean
Private mflgDirtyFlag As Boolean

The problem seems to be directly related to passing a recordset into the
class - through a sub or function.  I've tried making

Public Function Load_byInvoiceDetail

a sub and function - and have tried passing byVal and ByRef.  For testing I
changed the paramter to (xrst as ADODB.recordset) and then passed in a newly
created, plain recordset and it still bombs.

Of course, another question that stems from this - if you look at what my
code is trying to accomplish - can you overload the initialize method?  That
would be helpful!

Thanks a million,

- Tewks
