For my very first web application I created an ASP page with a TreeView Control on it for my company&#039s Intanet. Half my users are able to view the TreeView, the other half either get an error message saying the object doesn&#039t support the method "TreeView1.Node.add" or they just see an empty page. I believe the problem is an older version of COMCTL32.OCX. Is there a way to have the page identify if the user needs an updated OCX, and if so download it for them, then register it? If this is a simple problem, please for give me, as I said previously I&#039m new to the Web Development world.
