Hi all,

I need to do some cleanup just before application ends.

Which of these events are ok for that?

I will exist application using menu/exit it will fire pfc_exit but no pfc_close.

When I close application usig close mdi_frame x then it will fire pfc_close, but no pfc_exit.

I tried to find some info about correct life time of pfc application but did not find any.

Is it ok to fire pfc_exit from pfc_close (events from gnv_app instance)

Thank you Ales

 

EDIT>

The problem was, because I tried to find one place for some cleaning and auditing when app ends (by different type of ending).

I had break points to find that place.

Powerbuilder IDE while debugging did not stop at one place if i closed application by clickink exit in menu (then it stops in pfc_exit event of gnv_app) but did not stop in pfc_close event.  When I try to close app using Alt+F4 then debugger did not stop in any place (pfc_exit, pfc_close nor in destructor of gnv_app)

After hours of debugging and trying I restarted PB and then it stops in pfc_close every time and every type of closing app. So that the problem was some strange behaviour of PB Debugger :-(
