Treeview

how to use treeview in VB.NET?

'node
Dim nod As Node
Set nod = TreeView1.Nodes.Add(, , "root", "Customers", "msn")
nod.Expanded = True

I tried this code but it already doesn't work in VB.NET.
Kindly help me?

VB Code:

Dim nod As TreeNode = treeview1.Nodes.Add("Customers")
        nod.Expand()

how to add a child node?

VB Code:

Dim nod As TreeNode = treeview1.Nodes.Add("Customers")
        nod.Expand()
        'add a child
        Dim child As TreeNode=nod.Nodes.Add("Edneeis")
        child.Expand()
