You can get a process using
GetProcessByName[
^]. But I am pretty sure that it is not wise to handle such tasks on form level. Because you will probably have many concurrent users of your application it is more likely that you need to handle this on application level. It is an other design issue that you use on server side a regular application as background worker, and not a service - and the problem is not that you use it, the problem is how you need to handle it.
