Windows Service: Running Script Or Executable From

[Amy L.]

I have a windows service where I would like to launch a script (bat, cmd,
vbs, exe, etc) from the service. This script should execute in the
background and not require any input from the user (i.e. not interact with
the desktop).

I have been looking at System.Diagnostics.Process.Start() to launch this
script.

Here are my questions based on this.
1.) Is this the right namespace to be using?
2.) I want the program to wait until the script finishes processing is this
possible?
3.) Is there anything else I should consider?

Thanks
Amy.

I would use System.Threading namespace or use delegates[1]
2.) I want the program to wait until the script finishes processing is this

This is the reason why i suggested delegates in #1 question, with
delegates, you can use callback function to grab whatever data you would
need from the asynchronous/synchronous call
3.) Is there anything else I should consider?
I would be concern with security on what you're trying to accomplish and
since i'm not exactly sure what task the script will do, i cannot
comment any further.

Thanks

System.Threading won't run scripts (or other .exes) and neither will delegates, so,
yes, you are looking in the right place.

Yes, you do a Process p = Process.Start("exename", "args"); and then p.WaitForExit();
Scripts don't do callbacks.

3.) Is there anything else I should consider?

comment any further.

Remember that the script will run as the user that the service is logged in as. By
default that is the LocalSystem account, which is fairly privelidged on the local
system.

Thanks
