How to prompt a " File in Use" message

[#1]

Hi,

I'm currently creating a JMP file which acts as a database. Therefore I would like to prompt a "File in use" message and keep the file locked for editing when someone else already opened the database and is making changes to the file. For example, the same message you get when you open an Excel file on a server location that is already in use by someone else:

I think I already found a part of the answer in the following Community post: Multi-User Access 

If I'm correct I would still need to figure out how to lock the table if it is opened by another user.

Could someone please help with creating such a script?

Thanks

Sorry, lost track of this. I made a video of the data table vanishing off the desktop and sent it to the development team. Thanks!
