Examples: Contains method (NotesViewEntryCollection - LotusScript®)
This agent creates a NotesViewEntryCollection of read documents, and determines if the first document in the "All" view is in that collection.
Sub Initialize
Dim session As New NotesSession
Dim db As NotesDatabase
Dim view As NotesView
Dim vec As NotesViewEntryCollection
Dim doc As NotesDocument
Set db = session.CurrentDatabase
Set view = db.GetView("All")
view.AutoUpdate = False
Set vec = view.GetAllReadEntries()
Set doc = view.GetFirstDocument
If vec.Contains(doc) Then
Print "The first document has been read."
Else
Print "The first document was not read."
End If
End Sub
