I have a very basic understanding on how the TreeView control works.  I was wondering if it is possible for a Node of a Node to have a Node? ... and so on.   It seems as if it stops at 2 nodes.  Is this a limitation or is it possible?  If so, how?

Simple example for 5 subnodes:

Option Explicit
 
Private Sub Form_Load()
  Dim root  As Node
  Dim nod   As Node
  Dim i     As Long
  
  Set root = TreeView1.Nodes.Add(, , , "Root")
  Set nod = root
  For i = 1 To 5
     Set nod = TreeView1.Nodes.Add(nod, tvwChild, , "SubNode" & i)
     nod.Expanded = True
  Next
  root.Expanded = True
End Sub

Better example showing usage of Keys and Node objects.

Option Explicit
 
Private Sub Form_Load()
   Dim nod              As Node
   Dim i                As Long
   Dim j                As Long
 
   TreeView1.Nodes.Add , , "Root", "Root"
 
   For i = 1 To 5
      Set nod = TreeView1.Nodes.Add("Root", tvwChild, "Item" & i, "Item" & i)
      For j = 1 To 10
         Set nod = TreeView1.Nodes.Add(nod, tvwChild, , "SubNode" & j)
         nod.Expanded = True
      Next
   Next
   TreeView1.Nodes("Item1").Expanded = True
   TreeView1.Nodes("Root").Expanded = True
 
End Sub
