Hi everyone, I am developing an application to real time data fetching from ZK fingerprint machines.I have 2 questions.

1. I used axCZKEM1_OnAttTransactionEx(string EnrollNumber, int IsInValid, int AttState, int VerifyMethod, int Year, int Month, int Day, int Hour, int Minute, int Second, int WorkCode) to insert data into db but I could not find device ID. I need to know which machine triggered this event.

2. Can I use axCZKEM1_OnVerify event listener, how can I implement ? required to use thread? I need to listen to multiple devices which I have connected. When someone verified his finger, data(device id,empid,timne) should be saved into db.
