Where to perform final processing before application closes?

I have been trying to write out data to storage when the form closes or the application terminates and have NOT been successful.

I first tried from the Form unit

procedure TForm1.FinalizeObject;
begin
inherited;
SaveData;
end;

and

procedure TForm1.FinalizeObject;
begin 
 SaveData;  
 inherited;
end;

neither of these attempts worked, therefore I rrearranged my code and tried it from the project’s unit

procedure TApplication.ApplicationClosing;
begin 
 SaveData; 
 inherited;
end;

and

procedure TApplication.ApplicationClosing;
begin 
 inherited; 
 SaveData;
end;

I have a w3_showmessage as the first line of SaveData, and it never gets called ever....so, if i can verify that one of these 4 methods is triggered, i could use one of them

What am i doing wrong? Thanks

  • As of writing, Smart exposes two new events in the application object:

    These will make it easier to handle shutdown sequences. The smart javascript bootstrap also calls application.terminate() automatically now, so your code should work fine.
