Accessing a PSMessages Collection
Use the PSMessages collection to return all of the messages that occur during the session. The following example finds all the messages listed in the PSMessages collections when the Component Interface Save methods fails. The example assumes that &CI is the Component Interface object reference.
If Not &CI.Save() Then /* save didn’t complete */ &COLL = &MYSESSION.PSMessages; For &I = 1 to &COLL.Count &ERROR = &COLL.Item(&I); &TEXT = &ERROR.Text; /* do message processing */ End-For; &COLL.DeleteAll(); /* Delete all messages in queue */ End-if;
As you evaluate each message, delete it from the PSMessages collection. Or, delete all the messages in the queue at once using DeleteAll.
If there are multiple errors when saving a Component Interface, all errors are logged to the PSMessages collection, not just the first occurrence of an error.
Considerations for Declaring Collections
You must declare all collections for C/C++ and COM as objects, or else you receive errors at runtime.
