call powershell from ASP

11-09-2006

can someone post an example or point me to one where I can write an ASP page
that calls powershell commands and displays results of a query like
"get-disks"?

thanks.

Here's a cheesy example that takes input from a form, evaluates it and
returns the result in a listbox on the page. Of course you should never put
this on a public website but it does illustrate how to host the PowerShell
engine in an ASP, how to expose Web controls to the script and how to use
the session object to manage the runspace.

What's the best way then to test this page? Do I save it as an aspx or asp
page? I guess I'm kinda new to ASP, cuz I'm totally confused by the
Default.aspx.vb name in the code. Is this what I name the file?

I tried running it on a test front end server and I got the following error.
Should I save the file as Default.aspx.vb?

Sorry for the newbie question

GC Postmaster Guest n/a posts	Re: call powershell from ASP What's the best way then to test this page? Do I save it as an aspx or asp page? I guess I'm kinda new to ASP, cuz I'm totally confused by the Default.aspx.vb name in the code. Is this what I name the file?
