The following example adds two Node objects to a TreeView control. To try the example, place a TreeView control on a form, and paste the code into the form's Declarations section. Run the example, and click the Node object to expand it.
Private Sub Form_Load()
' Set Treeview control properties.
TreeView1.LineStyle = tvwRootLines ' Linestyle 1
' Add Node objects.
Dim nodX As Node ' Declare Node variable.
' First node with 'Root' as text.
Set nodX = TreeView1.Nodes.Add(, , "r", "Root")
' This next node is a child of Node 1 ("Root").
Set nodX = TreeView1.Nodes.Add("r", tvwChild, "child1", "Child")
End Sub
