When saving getting Fatal Exception: Exception Code = C0000005

TheMSsForum.com: The Microsoft Software Forum

Hi All,
I've got a wierd problem when i'm doing a batch save. What I'm doing is
trying to import some data files into my application so I'm going down the
import files and copying them to live data files & saving them using
tableupdate. The files I'm updating are quite big ie they contain over 150
fields. Whats happening is during the update I'm crashing out with the
following error: Fatal Exception: Exception Code = C0000005 . However there
seems to be no consistency as to when it does this, infact sometimes it does
actually go thru the update OK & it never seems to crash in the same place.
Can anyone explain whats going on here because i'm at an absolute loss.
Cheers Simon

A C5 error is an Access Violation error and can be caused all kinds of
things. This low level error cannot be handled by VFP. Some causes I've seen
over the past years:

- resident virus scanners:
I advise only to use virus scanners that allow you to exclude certain
files, folders or file types from the scan process. Always exclude
DBF, FPT, CDX, DBC, DCT and DCX files. You may want to check the
following article:

- poor hardware (mostly network adapters):
Update the drivers or replace the hardware. I'd only invest in 100mb or
gigabit network adapters.

- ActiveX controls (OCX)
- corrupt index file content
- corrupt memo file contents
- corrupt resource files (foxuser.* / SYS(2005)):
Shutdown your app or VFP and remove the foxuser resource files. These
files are recreated automatically the next time you start your app/vfp.
Read this article to learn more about trouble shooting file corruptions.

- HP LaserJet 4000 driver:
Here's some documentation:

Sometimes it helps to remove the printer setup information from the
report files. Here's some info on how to do that:

If you're using VFP8, then you can prevent VFP from storing printer info
in the report files. To do so, uncheck the "Save printer environment"
option on the Reports tab of the VFP Options dialog.

The Microsoft KnowledgeBase contains quite a few articles related to the
C5 error.

Lots C5 errors are fixed by the VFP Service Packs. Make sure you're using
the latest Service Pack. For VFP6, it is SP5 which can be obtained here:
http://msdn.microsoft.com/vstudio/downloads/updates/sp/vs6/sp5/

For VFP7, it is Service Pack 1:

For VFP8, it is Service Pack 1:
