A better idea might be to add a Nodes property.

' Count root nodes only:
NodesCount = tvMine.Nodes.Count
'Count a node's child nodes by passing the node as a parameter:
NodesCount = tvMine.Nodes[SomeHigherNode].Count

As for having two properties, the only other reason I could imagine
needing another count property is to count how many items _could_ be
visible within the current object's immediate display area. Could be,
not are.
