Hi!

I found following in the MSDN Library - July 2001:

SYS(2340) - NT Service Support

Disables or enables support for NT service.

SYS(2340 [,0 | 1 ])

Parameters

0
Disables support for NT Service (default).

1
Enables support for NT Service.

Return Value
Character

Remarks
This function intercepts Windows logoff messages (WM_QUERYENDSESSION and WM_ENDSESSION) to Visual FoxPro and specifies whether to keep Visual FoxPro COM Server instances running or to shut them down. A Visual FoxPro application will terminate when the current user logs off Windows. If the application is a Windows Service, then that service will terminate. Enabling support for NT service will make it possible for Visual FoxPro applications to continue even if the current user logs off Windows.



>Does anyone know where I might look for more information about the SYS(2340) function? I have searched MSDN and VFP, but can not find out anymore information about the function. I have written a couple of VFP apps that run as a NT service using a 3rd party control, but I am not happy with their performance. Has anyone worked/written a VFP app as a NT service with any sort of success?
