AddHandler to BlockReferences And AttributeReference

[jcheard]

I use AutoCAD 2006 and have a number of VBA applications I want to port over to .Net

In VBA I could capture events on a particular BlockReference or AttributeReference using the following code in a class module "clsAttEvent"
{code}
Public WithEvents oAtt As AcadAttributeReference
Private Sub oAtt_Modified(ByVal pObject As IAcadObject)
'Stuff happens here
End Sub
{code}
as long as I had an object of type clsAttEvent in scope and had set the oAtt to an attribute reference

I can't seem to accomplish the same using the ObjectARX .Net Managed Wrappers

Is there a way to have a BlockReference or AttributeReference capture events in AutoCAD 2006 w/o having to capture all database events first and filter?

If not, what is the earliest version (if any) of AutoCAD that allows events to be bound to BlockReferences or AttributeReferences?

There is no DBObject/Entity level of event (Erased/Modified/...) exposed in .NET API until Acad2009. With Acad2006-8, you have to do it at Database level, e.g handling Database.ObjectModified event. The ObjectEventArgs provides a reference of DBObject type to the modified entity

Hey Norm.

Thank you very much for your input. You've told me exactly what I needed to know!
