PB2019R3, b2703
PostgreSQL database from Enterprise DB, v12.5
Windows 64 bit platform
32 bit, PFC-based application


I'd like to grab the name of the object when a database error occurs:
   1) Embedded SQL = the name of the current window, tab, or tabpage
   2) DS = the name of the datastore whose database operation failed
   3) DW = the name of the datawindow whose database operation failed


Example: 
   A DBERROR event has been triggered and a MessageBox is created in the corp_n_tr.dberror event.
   How can I find the object currently with focus in that dberror event?

Q1:   Does PB have a string that stores the object currently with focus?

The only path I've come up with is to place code into the PFC to capture the object with focus, maybe in a global variable, more likely in gnv_app.is_object_with_focus (or something like that).

Q2:   Is there another way to approach this?


Many Thanks,

Olan
