Author dbfcdx error 1012 corruption detected (dos error 5)
noun

Hello:
I'm compiling an app. using:
clipper 5.2e, blinker 6, protected mode, rdd: dbfcdx

The application were running without problem when the error described
in subject arises, i suppose when i started to use IDX indexes in
conjunction with CDX (but not sure)

When one user accesses one record (locking it) to modify a field (that
is part of a cdx tag), and another user try to access the same record,
application hangs. Also hangs just when trying to open the same
database, using "use" command.

I've tried enabling the opportunistic locking but the situation became
worse.

Is there any prevention about using CDX in conjunction with IDX
indexes?
Functions that create IDX are reports or similar that use database for
read only purposes
Thanks in advance

DOS Error 5 - Access Denied
Maybe you've opened the first instance of the DBF exclusively??

Not in my experience - mix and match all you like
- although I didn't do it with DBFCDX (only SIXDRIVER V3))
- DBFCDX in Clipper 5.2e is a cut down version of SIXDRIVER V2.?

Thanks Steve:
I'v heard about "sixdriver". Could you explain me :
The driver i'm using is the one downloadable from c.a. In most cases
i'm not having problems.

About sixdriver3:

1) Is that driver compatible with Foxpro or Vfp6? (may be i have to
share database between clipper 5.2e and visual foxpro 6.
2) Where can i get the driver? Is it free?

Thanks again
Daniel

I believe the IDX/CDX format is compatable, you need to be aware of differences
that VFP makes in the DBF headers & field types.
