Nodes & Sub-Nodes selection

I’m new to VB.net (2003) and I want to create an index type app.

I have a Treeview with nodes & sub-nodes

e.g.

+ Hardware
    - Desktop
    - Laptop
+ Software
     - Word errors
     - Excel errors

With assistance from an Expert from a previous Question… I was able to select Hardware (node) and select sub-nodes which if double-clicked would activate a popup form.

The problem I’m having is selecting the other Nodes (ie Software) Node and its sub-nodes).

Can anyone help

Just Create one form, one Tree View and one Button and in the Button put this code on it and test it and see if it is what you want.

        Dim mainnode As TreeNode = New TreeNode("Main Node")
        mainnode.Nodes.Add("test1")
        mainnode.Nodes.Add("test2")
        mainnode.Nodes.Add("test3")
        TreeView1.Nodes.Add(mainnode)
