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
