Hello, the following code selects recursively the Outlook folders and
shows these in a Treeview. Everything works nice. I have the following
problem:

I would like have a TreeNode a text and two more values assigned to
this TreeNode e.g. an UserID and a Text.

These two information should not be visible. But if a user selects the
TreeNode i would like to read the information of the selected
TreeNode.

How can I build that in the code below??? I read about Inheritance but
i dont know how to implement those thing in my code below. For your
assistance I would be very grateful.


Private Sub Button3_Click
' Dim Application As Outlook.Application
Dim root As TreeNode
TreeView1.Nodes.Clear()
root = TreeView1.Nodes.Add("Outlook Root")
AddChildren(root, oNS.Folders)
End Sub

Private Sub AddChildren(ByVal root As TreeNode, ByVal list As
Outlook.Folders)
Dim flr As Outlook.MAPIFolder
Dim newRoot As TreeNode
For Each flr In list
newRoot = root.Nodes.Add(flr.Name)
AddChildren(newRoot, flr.Folders)
Next flr
End Sub


thanks

Derive your own node class from the Treenode class. In it's constructor pass
all the additional information you want to store with the node. For each
node, create a new instance of your own class.

public Class MyTreeNode
inherits TreeNode

public readonly Folder as Outlook.MAPIFolder

public sub new(Folder as Outlook.MAPIFolder)
mybase.new(folder.name)
me.folder=folder
end sub
end clss


Private Sub AddChildren(ByVal root As TreeNode, ByVal list As
Outlook.Folders)

Dim flr As Outlook.MAPIFolder
Dim newRoot As MyTreeNode

For Each flr In list
newRoot = New MyTreeNode(flr)
AddChildren(newRoot, flr.Folders)
Next flr

End Sub
 
Hi,

thank you! But there is only one Problem: I can't see the nodes! there
is no error and when i let show the name of the folders in the class
with messagebox it shows me all foldernames. but they aren't visible
in the treeview. there is no node created.

thanks

For example, in the AfterSelect event:

dim MyNode as MyTreeNode
mynode = directcast(e.node, MyTreenode)

msgbox mynode.folder.name
