Why not create a single file - with a single record, a File Lock Flag.
So - when a user goes to reindex files - they MUST Lock that one record
1st. Then, at the startup of your system - for regular users - the
system must check that flag & record to see if someone locked it and is
indexing files.
It's a thought...

We have a vfp9 SP2 program that has been running nearly bug free for
over 10 years. Only now we have a need to find out if anyone else is
using the exe in a specific folder. We allow many users to have their
own unique folder with their patient data files.
So we log into folder 1 and another user is in folder 2. No problem.
If we log into folder 1 and another user is in that same folder, again
no problem. Our software is multi-user down to the individual record
level. The problem is when the 2nd user comes in and needs to lock
many or all files to reindex or other procedures. How can the 2nd user
know that another user is there? Again it is not a problem until that
1st user starts to do something, almost anything that requires
accessing files. All files are locked by the 2nd user so the 1st user
starts getting errors.
We could try to lock the exe and that would fail so we would know
someone else is using the software. However, if that other user is
working with data in a different folder, we don't care so we do not
want to lock the exe.
Hope that is clear
