I need help with the TreeView control! I need to know how to add Root items and child and parent items etc, and if an item is selected to display something in a label or whatever. I've looked at the MSDN article on the TreeView control, but that didn't help at all.

Glad to see that i'm not the only one who thinks MSDN isn't overly helpful!

Give this a try as a starter?

Dim XNode As Node

Private Sub Form_Load()
'set up treeview properties
TreeView1.Style = tvwTreelinesPlusMinusPictureText
TreeView1.LineStyle = tvwRootLines

'add root nodes
Set XNode = TreeView1.Nodes.Add(, , "Root1", "Root1")
Set XNode = TreeView1.Nodes.Add(, , "Root2", "Root2")
Set XNode = TreeView1.Nodes.Add(, , "Root3", "Root3")

'add child nodes
Set XNode = TreeView1.Nodes.Add("Root1", tvwChild, "Root1Child1", "Child1")
Set XNode = TreeView1.Nodes.Add("Root1", tvwChild, "Root1Child2", "Child2")
Set XNode = TreeView1.Nodes.Add("Root1", tvwChild, "Root1Child3", "Child3")

Set XNode = TreeView1.Nodes.Add("Root2", tvwChild, "Root2Child1", "Child1")
Set XNode = TreeView1.Nodes.Add("Root2", tvwChild, "Root2Child2", "Child2")
Set XNode = TreeView1.Nodes.Add("Root2", tvwChild, "Root2Child3", "Child3")

Set XNode = TreeView1.Nodes.Add("Root3", tvwChild, "Root3Child1", "Child1")
Set XNode = TreeView1.Nodes.Add("Root3", tvwChild, "Root3Child2", "Child2")
Set XNode = TreeView1.Nodes.Add("Root3", tvwChild, "Root3Child3", "Child3")

End Sub

Private Sub TreeView1_NodeClick(ByVal Node As MSComctlLib.Node)
Label1 = Node
End Sub


Hope it helps

Also, take a look at the TreeView solution I posted here: http://www.experts-exchange.com/Programming/Programming_Languages/Visual_Basic/VB_Controls/Q_20921800.html

Read the poster's requirements closely before looking at the code.

I have a problem with the code Bobeo gave me.

Private Sub TreeView1_NodeClick(ByVal Node As MSComctlLib.Node)
Label1 = Node
End Sub

That doesen't work. I get an error saying:

"Compile Error:
User-defined type not defined"

And it highlights
Private Sub TreeView1_NodeClick(ByVal Node As MSComctlLib.Node
