In this case, the thing writing to the event log would be Task Scheduler itself or something else in Windows. And events and are always a 1. This applies not just to my manual experiments, but also includes every other random program that's using scheduled tasks, e.

Dropbox and Google updaters that are working as far as I know. Put all this together and I would strongly bet that the events generated while starting up a scheduled task are hardcoded by Windows to use an opcode of 1 when writing to the event log, and the events generated while finishing a task successful or not - which goes in the Last Run Result are hardcoded by Windows to use an opcode of 2 when writing to the event log.

This opcode appears to be a red herring that doesn't affect anything we need to worry about beyond curiosity. Okay I know I am late to the party here, but I think a lot of the problem stems from confusing the Operational Code with a Return Code. I'm not an expert in Windows programming or internals I make a living using a Windows system to program, but my programming isn't for Windows systems.

I had to re-create the task and set its "configure for" to Windows Server , Windows XP, or Windows I dont understand why, since its not for any of those OS' but after I did so my task actually worked. If this runs, and works, yet you still get an error code try entering exit 0 at the end of your script. Opcodes are attached to events by the event provider. An opcode defines a numeric value that identifies the activity or a point within an activity that the application was performing when it raised the event.

Opcode 1 means that, when producing the event, the application was in the start of an activity. Opcode 2 means that, when producing the event, the app. Download Microsoft Edge More info. Contents Exit focus mode. Please rate your experience Yes No.
