Alternatively, since this is a collection after all, you can Invoke
using DISPID_NEWENUM, QI the returned IUnknown pointer
for IEnumVARIANT and use that for enumeration.

Hi Igor

You're right, it's more like a VB collection. I'll stick to invoking the
count and item properties/methods, as you suggest.

Thanks for you help

Thanks for the reply. The documentation says:

The SelectedList property is a return collection that contains Long
values. These values are the list of map objects selected with the
PickQuick dialog.

The VB example provided has these lines of code:

       For i = 1 To pickQuick.SelectedList.Count
           str = str & " " & pickQuick.SelectedList.Item(i)
       Next i

I'm therefore presuming that it's a VB array.

On what basis? The syntax looks noting like accessing a VB array.

What you get is an automation object implementing Count and Item
properties.

How do I get to this safearray or do I have
to invoke the count and item properties/methods?

Yes, you have to invoke properties.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
