Here's basically what I'm trying to do. I have a treeview that I have filled. The treeview is located on a form with another subform when I click on the 1st node I want the record on the subform to reflect this. Sort of like a relationship you would see with a one to many. Any ideas would be appreciated.

How I accomplished this was when I was filling the tree, I placed the primary key of each record (hence, each treenode is unique) into the nodekey of each treenode. Then when the user clicks on a node, you simply read the primary key from the nodekey, and load the correct record into your subform.

grtammi: Where do you get your activex information? Are there tutorials out there for using them within Access? All my searches either turn up VB or ADO.NET programming, but I want to see the use in Access.
I have found to be a site that deals much heavier with treeview controls, especially the UI Design forum. But I still prefer tek-tips for answers to problems
The site is set up for attachments, and I have gotten probably 4 or 5 treeview examples from there.

Hi,
Check Helen Feddema's site. A nice treeview example is there.

I'm not sure where I figure this stuff out from, but here's a piece of example code that I use for my Treeview control (there's a blurb about halfway down on how to use the Treeview control):

Thanks for the code snippet, * 4 U.
I really want a resource to learn more though. Take imageLists for instance. How they correlate with TreeView's is totally foreign to me, and i can't seem to find indications of how to use them together (though I have completed examples of them).
I it all the same as in VB? Should I just look into VB explainations rather than Access specific ones?
Thanks. Sean.

Dear Perrymans,
VB Manuals are great places to get code samples.
Here is a link to MSDN for the TreeView control(and other controls):
Then Navigate to:
Visual Tools
Visual Studio 6.0
Visual Basic 6.0
Product Documentation
Using Visual Basic
Components Tools Guide
Using Active X Controls
(finally, pick the control you need)
Microsoft has it all, but it certainly is tough to find it!!
Hope This Helps,

you say you have a "one-to-many" type relationship on your subform ... then what I'd do is once I've got the value from the treeview control (the one-side), I'd either filter my subform with that value, or building a new SQL statement and reset my subform data source:
...
set ctl = forms!MyMainForm!MySubFormControl
ctl.Form!RecordSource = "SELECT * FROM MyDataTable WHERE MyRestrictedField=" & TreeViewTextValue & ";"
...
Of course, you'll have to make the mods where appropriate, but that should get you a little further along.
