we are planning to develop ASP.Net webservices for methods provided in Zkteco SDK.
One of the web-service is to Connect to the device. After invoking "Connect_Net(string IPAdd, int Port)" method, the connection is successful, also in the method, we register few events such as below:-
public bool Connect_Net(string IPAdd, int Port)
if (objCZKEM.Connect_Net(IPAdd, Port))
//65535, 32767
if (objCZKEM.RegEvent(1, 32767))
// [ Register your events here ]
// [ Go through the _IZKEMEvents_Event class for a complete list of events
objCZKEM.OnConnected += ObjCZKEM_OnConnected;
objCZKEM.OnDisConnected += objCZKEM_OnDisConnected;
//objCZKEM.OnEnrollFinger += ObjCZKEM_OnEnrollFinger;
objCZKEM.OnEnrollFingerEx += new _IZKEMEvents_OnEnrollFingerExEventHandler(ObjCZKEM_OnEnrollFingerEx);
objCZKEM.OnNewUser += ObjCZKEM_OnNewUser;
objCZKEM.OnFinger += ObjCZKEM_OnFinger;
//this.objCZKEM.OnVerify += new zkemkeeper._IZKEMEvents_OnVerifyEventHandler(ObjCZKEM_OnVerify);
objCZKEM.OnAttTransactionEx += new _IZKEMEvents_OnAttTransactionExEventHandler(zkemClient_OnAttTransactionEx);
return true;
return false;
But after connection, those events (OnEnrollFinger, On Clock-In etc..) are not getting invoked in ASP.NET Webservices.
Similar listeners work fine in a windows form application.
Can you please advice on how to resolve this?, should the above events be registered in a background thread?, if yes then how to do so?.
Thanks

Thank you, but how do i develop a seamless solution, where get-data and listeners work properly?

I would suggest you separate the listeners - using windows form/service, to pass real-time data to web api/service. And use web service to expose data to other applications
