VB6 check/stop application running on the network pc's

[dirkdev]

Hi,
I have a network where 5 users are running there local copy of a VB6 application, so the exe file is on all 5 pc's. The database they use is a MS Access database, placed on the server of the network.
The database must to be compressed and backuped each day during the night. Compressing an backup can only be done if all users closed there VB application. I need some way to close down the application on the 5 pc's automatically if the user didn't do it when he left the office. Doing so the database will be closed.
But... how can i -using VB6 code- check in the network if the app is running and how can i stop it on all 5 pc's ?
Any ideas ?

I think it would be much easier to modify the software on the users machines. You can add a timer that checks the time every .5 hours or so and if it is after 6:00 PM then shut down the software. Or a watch dog type addition to the software in that if the software is inactive for a given length of time it shuts down. Of course you need to consider any information that may need to be saved before it shuts down also. You could make a temp file on the PC that saves the current entered information before shutdown and retrieves it when the software is restarted.
