Clipper 5.2e + COMIX application & FWH

Robert Frank · Post by **Robert Frank** » Tue Feb 12, 2008 4:18 pm

I have few old applications made in clipper 5.2e + comix.

Is this safe to run at the same moment FWH application (xHarbour) on the same dbf and cdx files.?

I use:
SET DBFLOCKSCHEME TO 2

What can I do to prevent dbf or cdx files damage?
Is this possible to use both of systems in one time?

In theory, it's possible to do this without damaging the files. However, I don't have any DOS clipper 5.2e apps currently coexisting with xHarbour apps using the same files. Thus I can't tell you "yes" for certain.

I suggest that you create a set of test files and then access them with a simple test app that has versions in DOS Clipper 5.2e and also in xHarbour, and then run both apps at the same time and see what happens. In addition to the dbf and cdx test files, I suggest that your test files include an FPT memo as well to make sure that memos won't get corrupted.

If you don't already have xHarbour, you can find out how to download it for free from xharbour.org in order to do your tests.

Robert,

i use a mixed system of Clipper 5.2e programs ( comix and dbfntx files ) together with xHarbour's dnfntx and dbfcdx.

I also set
SET DBFLOCKSCHEME TO 2

But for my Clipper apps i added "FI NTXLOCK2" to my link script.
Without i had some troubles with error dbfntx 1012 index corruption.

But now it's working ok in our network.

Regards,
Detlef
