I created a PDF with form fields that our users (Reader 9, Windows XP) fill out and save.
It turns out that multiple users need to fill out a specific instance of a form (= file).
If one user opens the file, and another already has it open, when the users try to save, it gives them an error.
What I would like to is to have a warning for the 2nd user that someone already has the file open, and they should try again later (kind of like the Microsoft Office warning if you open an Excel/Word doc that someone else already has open).
Any suggestions/references on how to do this? I've not been able to find anything ... thanks!
