Retrieves the unique identifier for the instance of the device.
object.GetGuidInstance() As String
Returns the GUID for the device instance, in string form.
If the method fails, an error is raised and Err.Number is set.
An application can save the instance GUID into a configuration file and use it at a later time. Instance GUIDs are specific to a particular computer. An instance GUID obtained from one computer is unrelated to instance GUIDs on another.
