Retrieving Properties

Microsoft® Windows® 2000 Scripting Guide

Properties are the attributes associated with an object. They are particularly important in system administration scripting because many of the objects you use are virtual representations of actual objects. For example, in line 3 of Listing 2.2, the FreeSpace property is retrieved, using the same dot notation used to call methods.


With WMI, this object reference refers not to some amorphous programming construct but to an actual hard disk within the computer. The FreeSpace property is thus not just a property of an Automation object but also of drive C. In a sense, WMI creates a virtual mirror of an actual physical object. When you retrieve the properties of that virtual mirror, you also retrieve the properties of the physical object.
