You may have to write a listener and periodically have it cycle through the environment for the things you need to update. You could also write a "pusher" using something like winsoc that would notify your client, the VFP desktop GUI that it need to fetch up changes.

In most business situations, no two "clerks" will be working the same "bundle" of information. For example - two AR clerks will never enter the same payment or sale (and rarely will two AR clerks process for the same account (customer).

As others have said - treeview does not bind. Binding is usally slow anyway - so avoid it when you can. Hard "assignments" are faster and more reliable. So if performance rather than "ease of programming" is the priority - get comfy with coded assignments.222

If you want info on adding and removing nodes there are several good projects in download. You can check download #16575.

You can also build and "drive" treeview from the command window, It is a great way to learn from mistakes!:-)
