>Hi,
>
>One of my clients has an application that uses a very old 3rd party application that uses some sort of treeview control (I think it is using Comdlg32.ocx or MSComCtl.ocx from the installation). This seems to give grief at times (especially installing it on Win 10). The 3rd party application itself is now very old and no success at updating it.

>So I am thinking since they use only a bit of functionality in the app that I might just write the code to replace it myself.

>Does anyone have any pure VFP code that creates a treeview (data driven from tables so users can add folders)? Or does anyone know of any addin product that works well - especially under Win 10. It would be nice to not to have to install anything.

>Or maybe there is something newer that can still be called from VFP that is already installed in Windows.
