VFP is not responding

[Vandolfph]

i have a prg file that backups my data,
and after building it as an exe file, when i execute the prg file, vfp is not responding.
but in my project, it runs smoothly without error..

here is the error log.
Fatal error: Exception code=C0000005 @ Friday, January 29, 2016, 11:59:56 AM. Error log file: C:\output\VFP9rerr.log

Well, what is the code of databak.prg, especially (but not only) line 6?

Bye, Olaf.

In regard of "VFP is not responding": If you do a loop (any loop FOR/FOREACH...ENDFOR, DO WHILE..ENDDO to SCAN...ENDSCAN not only sepcific loops) where no DOEVENTS occur, or anything else putting your app into an idle state once in a while, you make an application unresponsive. Windows watches over processes not acting on their Windows event queue, and VFP code in such a "thight" loop does not do so. Within any normal app you get to a READ (legacy code) or READ EVENTS (the one event handling "loop") and DOEVENTS simply calls the event handling of currently queued events.
