Hi all,

I've written a windows service in VFP9 which was built on XP SP2 and it works fine when I run it as a service. I get the desired result back which is printing bills to JPG images.
But when I test on our target machine, when I run as a service I get an error noted in the title of this thread. However, if I run it interactively (by double clicking the exe through explorer) then everything works as it should. What's the diference? Why is it failing?

Below is my OS version info.

OS(1)= Windows 5.00------ Description: the name and version number 
OS(5)= 2195-------------- Description: build number 
OS(6)= 2----------------- Description: the operating system platform.
OS(7)= Service Pack 4---- Description: Service Pack 

Here is my code:

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\") ;
	)

DEFINE CLASS CIAEA as Form 
  FUNCTION DeliverService(lpnWhich as Integer)
    LOCAL llReturn as Logical 
    m.llReturn = .t.
    DO CASE 
      CASE m.lpnWhich = 1 && Print bills
        * Code omited 
        TRY 
          this.poJPGListener.targetfilename = m.lcFileName
          this.poJPGListener.ListenerType=2

          IF FILE(m.lcFileName) ;

          ELSE 
            THROW "Bill not created"
          ENDIF 
        CATCH TO loE
          this.LogError()
          m.llReturn = .f.
        ENDTRY         
    ENDCASE
