This example moves the navigation pointer to the next node, unless the current node is the last node of the level in the navigation structure.
Private Sub MoveNext()
Dim theNode As NavigationNode
Dim theNextNode As NavigationNode
On Error Resume Next
Set theNode = ActiveWeb.HomeNavigationNode.Children(1)
Set theNextNode = theNode.Next
If Err <> 0 then
MsgBox “End of the current navigation row”
End If
