    Default NT Service with networking support

    Hi everyone!

    I need NT Service(ofcource without GUI) but with some networking support(UDP server).
    Networking depends on QCoreApplication, but i have no idea how to implement service with QCoreApplication.

    My reference service code is here. It works, but how to embed QCoreApplication in it?
    May be there is some other way to implement NT service application?
    Using Qt5.3.2 VS2013
    Qt Code: 
    1. // Beeper Service.cpp
    2. // Copyright (c) 2001-2002 Jarmo Muukka. All rights reserved.
    3. #include <windows.h>
    4. #include <tchar.h>
    5.  
    6. TCHAR* serviceName = TEXT("Beeper2 Service");
    7. SERVICE_STATUS serviceStatus;
    8. SERVICE_STATUS_HANDLE serviceStatusHandle = 0;
    9. HANDLE stopServiceEvent = 0;
    10.  
    11. void WINAPI ServiceControlHandler(DWORD controlCode)
    12. {
    13. 	switch (controlCode)
    14. 	{
    15. 	case SERVICE_CONTROL_INTERROGATE:
    16. 		break;
    17.  
    18. 	case SERVICE_CONTROL_SHUTDOWN:
    19. 	case SERVICE_CONTROL_STOP:
    20. 		serviceStatus.dwCurrentState = SERVICE_STOP_PENDING;
    21. 		SetServiceStatus(serviceStatusHandle, &serviceStatus);
    22.  
    23. 		SetEvent(stopServiceEvent);
    24. 		return;
    25.  
    26. 	case SERVICE_CONTROL_PAUSE:
    27. 		break;
    28.  
    29. 	case SERVICE_CONTROL_CONTINUE:
    30. 		break;
    31.  
    32. 	default:
