Hi,

only for reference I will try to put together the current incarnations of the DBFCDX database I'm aware of:

- FoxPro, the original one. Latest release was 2007, current copyright holder is Microsoft. This product is officially dead.

- SuccessWare, first appeared in Clipper 5.2. Current implementation is ApolloDB, latest release January 2018. No RDD for VO, only Ado.NET and Delphi VCL. There is also a server edition, ApolloDB Server. The company seems to be alive.

- Comix, first appeared in Clipper 5.3. The original developer was Dave Kuechler, LoadStone Inc. This implementation was sold to CA and used in both VO and Vulcan.NET. There was also a server edition named Fortress and sold also by GrafX. AFAIK Dave Kuechler died several years ago.

- Codebase by Sequiter, a C/C++ library. The company is gone.

- Harbour/xHarbour. Implementation in C/C++, open source.

Wolfgang

P.S. the FlagShip people has done their own RDD DBFIDX - if you need to access DBFCDX databases from FlagShip applications you need CodeBase.

Hi Wolfgang,

Currently I use routines written in Clipper 5.2 recompiled in Harbour 3.0 using dbf. They are not bad.

Since the Harbour drive are open source could it be a good starting point for implementing X# drive RDD?

Ciao Fabrizio,

I think the same. Since the X# drivers will be open source too, this should be possible.
I don't know the Harbour license, but I don't think it would be possible if the X# driver would be closed source.

It is a pity that most other (tested and working) implementations are dead now....

Ciao Wolfgang,

I go to memory, they should be freely editable enough to also distribute the original sources. however I think that the xHarbour / Harbor community could like to have the implementation in X # and anyway it should not be impossible to find agreements with the Harbour's developers

Hello,

after doing some tests with ApolloDB in X# I sent a few questions to the producer, the first time as email, the second time from their web form.
Unfortunately, I haven't received any answer from them.

Yesterday I decided to buy a license because I needed that for a small utility. Their webshop declined both of my creditcards I tried - and again I sent them a message through their webform - and again without any answer.

Attached to this message you can find my X# application that executes a SQL select to a DBF using ApolloDB (the demo version).

Wolfgang,

Maybe the sales people at Apollo went to the same marketing training that the sales staff from GrafX attended <g>.

Indeed. I remember having received an email from this 'sales staff' after multiple attempts, on a very reasonable question, with the word "I chose not to answer".

That seems to be a policy of many nowadays. On one hand companies spend millions to buy or collect customer behavior data and on marketing efforts while just keeping a customer happy by reacting promptly on questions or complaints, a much less expensive option, is far less common.

Hi Dick,

this is really a pity.... for some applications this library could be interesting, but the lack of responses makes it unusable.
