The Parent property returns the parent of the object. Read-only.
Set objParent = object.Parent
Object
The Parent property in the CDO for NTS Library returns the immediate parent of an object. The immediate parent for each object is shown in the following table.
CDO for NTS Library object | Immediate parent in object hierarchy |
---|---|
AddressEntry | Message |
Attachment | Attachments collection |
Attachments collection | Message |
Folder | Session |
Message | Messages collection |
Messages collection | Folder, including Inbox or Outbox |
Recipient | Recipients collection |
Recipients collection | Message |
Session | Set to Nothing |
The Parent property represents the immediate parent of the object, rather than the logical parent. For example, a folder contains a Messages collection, which contains Message objects. The Parent property for a message is the immediate parent, the Messages collection, rather than the logical parent, the Folder object.
The Session object represents the highest level in the hierarchy of CDO for NTS Library objects and its Parent property is set to Nothing. The AddressEntry object does not have a true hierarchical parent but can only be obtained through the Sender property of a Message object. Its Parent property returns the Message object.
For more information on the CDO for NTS Library object hierarchy, see CDO for NTS Object Model.
This code fragment displays the Class of the parent Messages collection of a Message object:
' Function: Message_Parent Function Message_Parent() ' error handling here ... If objOneMsg Is Nothing Then MsgBox "Need to select a message; see Messages->Get*" Exit Function End If ' Immediate parent of message is the Messages collection MsgBox "Message immediate parent class = " & objOneMsg.Parent.Class ' error handling code ... End Function
To get to the Folder object, you have to take the parent of the Messages collection:
' Function: Messages_Parent ' Purpose: Display the Messages collection Parent class value ' See documentation topic: Parent property Function Messages_Parent() Set objMessages = objOneMsg.Parent ' error handling here ... If objMessages Is Nothing Then MsgBox "No Messages collection available" Exit Function End If MsgBox "Messages collection parent class = " & objMessages.Parent.Class Exit Function ' error handling here ... End Function
