No. The client will be updating the database. It is more an issue of ensuring no users are in the program while the update is running. If this was a single user prograM then it is easy to check and force a close. I am not sure when there is more than one user (from different computers)

Hi I have created a program that is intended to be used by multiple users (each on their own computer) who access the same SQL database. I have also created a separate updater program to sit alongside the main application. However, I am unsure how to check if there are any users in the main program before the update is run. (This is easy to do on a single user application but not sure on multi-user). Any help is greatly appreciated (I am relatively green here so please be kind)
