There are times when it is handy to start will a null collection in a NotesDocumentCollection., for example when you want to add documents to a collection programmatically based on something other than selected documents in a view.
Two good methods for doing this are:
Method 1:
Dim session As New NotesSession
Dim db As NotesDatabase
Dim collection As NotesDocumentCollection
Set db = session.CurrentDatabase
Set collection = db.GetProfileDocCollection("The name of a non-existent profile document")
