DO decl

LOCAL lnProcessId
lnProcessId = GetCurrentProcessId()
* hide by registering as a service mode program
= RegisterServiceProcess (lnProcessId, RSP_SIMPLE_SERVICE)
* show
*= RegisterServiceProcess (lnProcessId, RSP_UNREGISTER_SERVICE)
PROCEDURE decl
DECLARE INTEGER GetCurrentProcessId IN kernel32

Registering your application as a service mode program removes it from the Task List in Win95/98/Me. That means it cannot be so easily aborted by an advanced user who already mastered the magic triple-key forcer.
It is recommended to restore the regular mode (Simple Service) for your application before closing it, to let it free its system resources in a proper way.
The RegisterServiceProcess is a documented function in KERNEL32 library. Though MSDN doesnt indicate this particular result of calling it.
Here in VFP we are not much spoiled with header files as those guys with C are. Whichever external function is, it has to be declared directly in VFP code. Differently in C the RegisterServiceProcess function is not prototyped in header files. That is why they have to resort to LoadLibrary and GetProcAddress functions at first.
