Graphical Displays of Data Hierarchies on a Form

[StuartB60]

I have a table called THREAD. Each THREAD row can relate to another THREAD row in a parent-child relationship. A child can only be related to one parent. A parent can have many children.

I would like to be able to be able to present these relationships graphically using something like a treeview.

Can I use treeviews to do this - if so how? Whenever I try to use a treeview control it tells me I am not licenced. How/where do I get such a control from and then how do I install and use it?

If treeviews are not the answer does anyone have any other suggestions?

thanks
