Sorry just started playing with this code.
Not quite sure how to get the selected node?

Rory

Code:
 $TreeView = $Form.TreeView()
$TreeView.Width = $Form.ClientWidth / 4
$TreeView.Dock = 3

$MachineArray=MPW002841,MPW002842,MPW002843,MPW002844,MPW002845,MPW002846,MPW002847,MPW002848,MPW002849,MPW002850
$RootNode = $TreeView.Nodes.Add("Machine List",45,46)

For Each $Machine in $MachineArray
	$MachineNode = $RootNode.Nodes.Add("$Machine",45,46)
	$MachineNode.tag=$Machine
		$Logs = $MachineNode.Nodes.Add("Logs",45,46)
			$Audit = $Logs.Nodes.Add("Audit",45,46)
			$Diagnostic = $Logs.Nodes.Add("Diagnostic",45,46)
			$Distribution = $Logs.Nodes.Add("Distribution",45,46)
			$Installation = $Logs.Nodes.Add("Installation",45,46)
		$Services = $MachineNode.Nodes.Add("Services",45,46)
			$CNCService = $Services.Nodes.Add("NSPIS CNC Software Distribution",45,46)
			$SU = $Services.Nodes.Add("SU",45,46)
			$TimeSync = $Services.Nodes.Add("TimeSync",45,46)
