Hi Steve,
I found a DF that talks about
saving the tree to a spreadsheet file and have included it in this message. To get items from the tree control, you have to use open up the tree and remove all of the items off of that tree, while still preserving the heirarchy of the tree. The indent level property node will preserve the heirarchy of the tree and from there you can get the item tag and cell string.
To transfer the file to a tree, you will then need to read the file and insert items into the tree corresponding to the heirarchy. I have also found a tutorial on how to
traverse tree controls.
I hope this helps.
Regards,
