Get Checked Listview Items from Form to populate Treeview in a Different Form

[bhalbach]

I am really struggling to understand how to do this.

I have Form1 that has a treeView1. On Form1, I select a Node that I want to add a ChildNode to and then click Button1.
Button1 (on Form1) will open Form2 which contains a Listview1 with checkboxes.
I will then either...
Check items on the Listview1 that I want to add to the Node that I had selected on Form1 (could be 1 item checked or multiple) then click buttonAdd. The buttonAdd would return to form1 and add the selected items to treeview1 previously selected Node.
OR
I could also click buttonCancel (on form2) and select nothing and return to Form1.

I am really grasping to understand the treeview.

Can someone please assist me with this.

Private Sub buttonAdd_Click()

Form2.show

'This gives me an error Invalid Key'
Me.TreeView1.Nodes.Add Me.TreeView1.SelectedItem.Text, tvwChild, Form2.listview1.SelectedItem.Text, Form2.listview1.SelectedItem.Text

'This gives me an error Invalid Key'
Me.TreeView1.Nodes.Add Me.TreeView1.SelectedItem.Index, tvwChild, Form2.listview1.SelectedItem.Checked, Form2.listview1.SelectedItem.Text

'This gives me an error Index Out of Bounds'
Me.TreeView1.Nodes.Add Me.TreeView1.SelectedItem.Selected, tvwChild, Form2.listview1.SelectedItem.Checked, Form2.listview1.SelectedItem.Text


End Sub

You can use the CoCreateGuid API to create unique keys. I have demonstrated it HERE

I have taken a different route and decided to add the items to the ms Sql database and then populate the treeview from a recordset.

I am stuck trying to add the child nodes.

Can you assist?

The following is the code I am trying to use to populate from the recordset. All connections etc are working, and I can get the Parent nodes loaded but not the child nodes.
When I try to load the Treeview I get "Error number = 2147257114 Invalid object"
I am pretty lost with this.

Me.TreeView1.Nodes.Clear
    
    'load Treeview
    Do While Not rs.EOF
    
        Me.TreeView1.Nodes.Add = rs.Fields.Item("BidItemNo")
        Me.TreeView1.Nodes.Add rs.Fields.Item("BidItemNo"), tvwChild, rs.Fields.Item("BidItemDescription"), rs.Fields.Item("BidItemDescription")
       
    rs.MoveNext
    Loop

Tenho um exemplo que clicando no Nó da Treeview, os dados são carregados na Listview.
