Examples: GetParentDocument method

  1. This script finds the parent of the last document in the By Category view of a discussion database and displays its universal ID.
    Sub Click(Source As Button)
  Dim db As New NotesDatabase( "Byzantium", "discuss.nsf" )
  Dim view As NotesView
  Dim doc As NotesDocument
  Dim parentDoc As NotesDocument
  Set view = db.GetView( "By Category" )
  If view Is Nothing Then
    Messagebox "View not found"
    Exit Sub
  End If
  Set doc = view.GetLastDocument
  If doc Is Nothing Then
    Messagebox "Last document not found"
    Exit Sub
  End If
  If doc.IsResponse Then
    Set parentDoc = view.GetParentDocument( doc )
    If parentDoc Is Nothing Then 
      Messagebox "Error reading parent document"
      Exit Sub
    End If
    Messagebox parentDoc.UniversalID, , _
    "UNID of parent of last document"
  Else
    Messagebox doc.UniversalID, ,"UNID of last document"
  End If
End Sub
  2. This function takes a document and returns its ancestor -- that is, the original main document that began a response hierarchy. This is useful for discussion databases in which response-to-response documents often nest many levels deep.

    Function getAncestor ( doc As NotesDocument ) _
As NotesDocument
  Dim view As NotesView
  Set view = doc.ParentView
  If Not(Doc Is Nothing) Then
    While doc.IsResponse
    Set doc = view.GetParentDocument( doc )
    Wend
  End If
  Set getAncestor = doc
End Function
