Microsoft will no longer be developing .NET Framework after version 4.8 My concern is, my future software development will be in .Net Core 3.1 or newer, and may not support the existing MYOB API Microsfts support term will have a shortened support period for Long Term Support releases to three years - previously it was 10 years.

Dim Pur1Svc = New Purchase.ServicePurchaseOrderService(myConfiguration, Nothing, _oAuthKeyService) Pur1Svc.GetRange(companyFile, null, credentials, OnServicePurchaseOrderLineComplete, OnError) returns all service purchase orders as a paged list (usually 1000 at a time) with lines (if you do not use filters) loopint = 0 to bills,items.count-1 ... If Bills.Items(loopint).Lines.Count > 0 Then ... For lineitems = 0 To lvBills.Items(loopint).Lines.Count - 1 ... iterates through all PO line(s) in purchase order(s)
