C0000005 Error

[JimSeason]

When I am working with forms, new and old, I can make changes, run the form, no problem...once, maybe twice. I then get the infamous C0000005 error: Memo file is missing/invalid. A restart of VFP 9 fixes it and the process of edit/error repeats. Does anyone have any suggestions beyond what I have already tried?

Already tried:
1. Create new foxuser files
2. Running CHKDSK, scanning/fixing bad sectors
3. Opening errant form as table and looking for 'junk'
4. Using VFP without anti-virus running

BTW, my OS is Vista.

Thanks!

Make sure the form isn't saved in the Windows or Program Files folders.

The form is not saved in the Windows or Program File folders. Other suggestions? BTW, I'm runnning VFP 9 SP1.

In any case, thanks for the reply!

-Disable write behind cache for disks.
-If you are using an antivirus like nod32 remove dbf/fpt from check (remove anyway whatever the antivirus is) - oh just read no antivirus, brave heart

Tried setting all the VFP file types to excluded from AV checking.

Turned off the write behind cache.

I was able to make more changes in the form I've been working on but in the end I still get the error.

More suggestions?

Looping back to something you did, just to make sure you got them all/right ones. Did you get the ones in the HOME(7) folder?

I set exceptions for all the VFP file types no matter where the file is found.

We updated the video driver and the C5 errors disappeared. Not that this is a universal fix, but it did the trick for us - but we did NOT have memo file corruption as part of the mix.

For what it's worth
Once I've seen this behaviour with corrupted index-files.

Make sure not to leave your form.methods from within WITH..ENDWITH - example:
WITH ...
...
RETURN .T.
ENDWITH
