The Message object
The Message object is a predefined PowerBuilder global object
(like the default Transaction object SQLCA and the Error object)
that is used in scripts to process Microsoft Windows events that
are not PowerBuilder-defined events.
When a Microsoft Windows event occurs that is not a PowerBuilder-defined event,
PowerBuilder populates the Message object with information about
the event.
Other uses of the Message object
The Message object is also used:
-
To communicate parameters between windows when you
open and close themFor more information, see the descriptions
of OpenWithParm, OpenSheetWithParm,
and CloseWithReturn in the PowerScript
Reference. -
To pass information to an event if optional parameters
were used in TriggerEvent or PostEventFor more information, see the PowerScript
Reference.
Customizing the Message object
You can customize the global Message object used in your application
by defining a standard class user object inherited from the built-in
Message object. In the user object, you can add additional properties
(instance variables) and functions. You then populate the user-defined
properties and call the functions as needed in your application.
For more information about defining standard
class user objects, see the PowerBuilder Users Guide.
