I'm using a Treeview control for the first time. I found some code to load
the control. It works but all it does is load the control. One problem is
that it does not display the '+' for any root node that has children. It does
do it for lower level nodes. Any idea how to fix this? Also, where can I find
out how to add and delete nodes? I tried using the nodeclick event but as
soon as I coded that event, the tree ceased to function completely i.e. would
only display the root nodes and refuse to expand further.

Recommend you Google on Access and treeview.

You should get a bunch of URLs with explanations on how to perform various
treeview tasks.

I already did that, that's how I found the code to load the control. However,
nothing I've so far found shows how to get the '+' on the root level nodes or
how to implement adding and deleting nodes.

A couple of things which might be helpful:

Root level nodes will display a "+" symbol only if there are child nodes on
that node; they will never display a "-" symbol because they cannot be
collapsed.

The best example I've seen which illustrates the MS treeview control and its
capabilities is on Alex Dybenko's site. Have a look at
http://www.pointltd.com/Downloads/Details.asp?dlID=36

The most comprehensive documentation I've found on the treeview control is
on the MSDN Site. As a start, this gives the results of a search for
"treeview" on that site:
http://search.msdn.microsoft.com/search/default.aspx?siteId=0&tab=0&query=treeview
You should find something helpful there.

HTH,

Rob
