Vista - diskpart and WshScriptExec problem

Hello,

currently putting together a vbscript that is piping input to diskpart.exe
(from within winPE). It uses the WshScriptExec object with is sending input
commands just fine. The problem I'm having is that even know I'm piping the
'exit' command to diskpart it does not exit... I still see it's process
running in taskmgr... so my script loops infinitely waiting for that
WshScriptExec.Status to change from 0, which it doesn't since diskpart does
not exit. After I manually kill the task with taskmgr, my script breaks out
of the loop as expected.

the only command I'm sending diskpart that really takes any time is the
format command. Thats where my loop comes in and just sleeps waiting for
that WshScriptExec.status to change, signaling diskpart is done and has
exited. I would really like to make this work the way I have set out to do
but I know I have 2 other options: 1, do the format commands outside of
diskpart with the 'run' instead of the 'exec' method. This would alow for
running format.com synchronously eliminating the issue of not knowing when
diskpart is done, or 2, instead of piping the diskpart commands
interactively I could pipe them to a txt file which could then be supplied
as script file param to diskpart, again, using run instead of exec so that
its done synchronously.

but again, I really like the way I started this... much cooler in my
opinion, but I need to get this done so if anyone has any ideas as to why
what I want to do is not working please let me know. I'm going to bail on it
and move to an alternative by Monday.

thanks.

just an update: if someone knows more please do share.

I've decided to just move the format operations outside of diskpart. My
hunch is that diskpart's format command is probably just actually calling
format.com anyway, which is what may be causing my problem with the
WshScriptExec object.... the program I execute (diskpart.exe) is calling
another program (format.com) and so the 'wiring' between the program and my
object get screwy? Thats my hunch, I have to move on. Again, if anyone else
has any input on this please do share.

thanks.

thanks for the input OldDog. The problem though is that I would'nt know
'when' to kill the process. It runs asynchronously from my main script. I do
appreciate your response though. Thanks.

good point, I just double-checked and no, its not awaiting input. Thanks for
the good thought though.
