This property provides access to the PIConstants collection containing PIConstant objects. Each PIConstant object represents an enumeration and contains both the constant and a useful string describing the constant.
The object placeholder is an object expression that evaluates to a PISDK object.
PIConstant collections are useful in applications that provide pick lists of options to the user. For example the PointTypeConstants PIConstant collection can be used to display a list of names for supported point types and on selection the corresponding constant can be easily obtained for use in PIPoints.Add
