While I was playing with the following code, I discovered that if you put SYS(2335,0) in the init event of the class below, the exe just flashes and disappears. I am writing a windows service, so eventually I will want this function. At the same time, I am not able to run the exe when testing. The documentation says that the funciton only applies to _vfp.StartMode = 2 but doesn't state that it would stop an exe from running which wastes my time trying to find the cause of the problem.

PUBLIC oService as CIAEA OF MAIN.PRG

m.oService=CREATEOBJECT("CIAEA", ;
	IIF(_vfp.StartMode>0,ADDBS(JUSTPATH(_vfp.ServerName)),FULLPATH("")), ;
	IIF(_vfp.StartMode>0,ADDBS(JUSTPATH(_vfp.ServerName))+"data\",FULLPATH("")+"data\") ;
	)
MessageBox("Hello, what's going on?")  && I don't see this when I run the exe
m.oService.Show() && or this
READ EVENTS

DEFINE CLASS CIAEA as Form 
	PROCEDURE Init(lpcAppPath,lpcDataPath)	
		SYS(2335,0) && Unattended server support
	ENDPROC &&Init


	PROCEDURE Destroy
		CLEAR EVENTS 
	ENDPROC && Destroy
ENDDEFINE

So changing the code to this, then works:

if _vfp.StartMode = 2 ;
then 
	SYS(2335,0) && Unattended server support
endif
