Thank You to @ivan avdonin. I didn't know that.
Timofey, yes, it is a Russian application. What I want to do is, to run a batch file while client does the data exchange. I want to send series of command-line parameters so that it can:
1-> Terminate the user sessions (Something similar to /ЗавершитьРаботуПользователе)
2-> Update configuration (For this one I found: /UpdateDBCfg)
3-> Again allow users to be able to connect (Something similar to /РазрешитьРаботуПользователей)
So, how can I send parameters for step 1 and 3?
