WshScriptExec.Terminate returns error

[Gary]

I have a simple script, something like:
Set objShell = CreateObject("WScript.Shell")
Set objExec = objShell.Exec("myprogram")
Wscript.Sleep 10000
objExec.Terminate

I run this as a Scheduled task. If I stay logged on, it runs without error.
If I log off, the objExec.Terminate statement returns
c:\Scripts\Myscript.vbs(33, 1) (null): Invalid window handle.

I know the program runs, and exits when I execute objExec.Terminate. What is
the error telling me?

Thank you.

Scheduled tasks do not have access to the interactive console that the
Exec method requires. There used to be a way to enable this through
the old NT 'at' command - I just checked the help for Win2k and it's
still available. So, I guess that might be a way to schedule the job.

Or, if you don't need the access to the StdIn/StdOut functions, etc.
that Exec provides, you could just switch to the Run method instead.

The reason I used the Exec method is that I need to Terminate the task after
it has run for a period of time. That didn't seem so easy to do if I used
the Run method. I believe I will need to control the task scheduling through
scripting, also, so will have to use the AT form of scheduling.
