Get disk count using powerShell

In this example, the ‘Invoke PowerShell Get Result’ activity will get a count of discs/disks available to the desktop, using the Microsoft PowerShell command "(get-disk | measure).Count", then display the result in a Message Box.

To get the result, we use the "result" variable and set that to "String Result" in powershell activity properties.
