You are correct in that locking does not work under Windows, it does
work
fine under Linux/Unix.  I don't have any definite timeframe for
releasing
2.0 nor a list of features that will be in it.  The biggest thing for
2.0
is that it will be a merged version of xbd 1.2.0 and the development
code from the original xBase (1.9.x).

There is code in there (in lock.cpp) for DOS/Windows and it probably
wouldn't
take that much to make it work.  If you would like to work on it and
provide
patches that would be greatly appreciated.  Make sure to check out the
latest
version in CVS and keep me informed.

[XDB-users] Sharing with other apps ?

[Christophe <cco...@ap...>]

Hi !

I've read the doc and it seems that sharing isn't implemented yet and
will be released, perhaps in Xdb v2.0.
Is that true ? Is there any schedule about the release of Xdb v2.0.0 ?

I'm looking for a solution to develop a Web front end to an "old"
application using many dbx (and ndx and ntx) files.
I need that the web front end works meanwhile the current clients of the
app work (a front end running on Windows 3.11, DOS and Windows 95,
accessing the files on a novell server with IPX).
The connectivity between the web server we develop and the novell
server(s) (there are several ones) on wich the dbf are stored is ok
(using IP, no longer IPX).
What I need to be sure is that data sharing and files and recors sharing
will work fine.

Before choosing XDB, I need to know if it will work in such an
environment. Reading the doc it will not...

Can you give me some hints about that ? any schedule for v2 that
*should* implement this, or any link toward an other lib ?

As a C/C++ (and some nice others languages) developer I can help to
implement file and records locking if some specifications have been
written.

Best regards.

This will create, but not populate the index.   You must call
intx1.ReIndex()
to fill the index.

[XDB-users] creating index files

[Don <do...@lc...>]

Hi,

I am trying to create an NTX index file from a dBase III+ compatible file.
For some reason, the index file is created but they contain no records
(empty file).  Has anyone else experienced this?  My code looks like this:

#include <xdb/xbase.h>

/* set the stack large for dos compiles */
#ifdef __XBDOS
#include <stdio.h>
extern unsigned _stklen = 100000;
#endif

int main()
{
  xbShort rc;
  xbXBase x;
  xbDbf MyFile( &x );
#ifdef XB_INDEX_NTX
  xbNtx intx1( &MyFile );
#endif // XB_INDEX_NTX

  MyFile.OpenDatabase( "/home/ftpadmin/pub/websail.dbf" );

  if(( rc = intx1.CreateIndex(
  "/home/ftpadmin/pub/websail.ntx", "sportodis+sarrdate", XB_NOT_UNIQUE,
XB_OVERLAY )) != XB_NO_ERROR)
    {
       cout << "Error creating index 1 = " << rc << endl;
       exit( 1 );
    }

  MyFile.CloseDatabase();    /* close database */
  return 0;
}

	Nobody seems to answer you, so I will do it
	Linux is a UNIX like, most of the command works with the same name
and option.
	Unfotunately not the c compiler. In classic unix it is cc 
	in linux : gcc
	Please note that gcc and other gnu tools can be found in other unix
system, as solaris. gcc stands for gnu cc
	for C++, use g++ instead of gcc

	to compile a source code, most of the time, run a file that is named
configure. It will make a makefile for you
	then type make to build the source. This do not prevent you to read
the doc files ;)

	Hope it help you to start

What are you trying to compile?  The XDB library or a program?  If you
are trying to build the library, then you just need to run the config
script as:

	./configure

from the base directory and then build it by running make:

	make

and then install it with:

	make install

If you are having problems compiling and linking a program you might
want to look at the Makefiles for the samples and/or watch the commands
make executes.  Basically, though, to compile and link a simple program
in
the file 'myprog.cpp' using the XDB library you would use the command:

	gcc myprog.cpp -o myprog -lxdb

Unless you are using the code from CVS, in which case it would be:

	gcc myprog.cpp -o myprog -lxbase

Hope this helps,

I have looked through all the dbase stuff on the web and dbase 5+ does have 2
facilities to encrypt tables (one is called the PROTECT mechanism, and the
other ??  is an admin type thing)

I have not been able to find any open libraries or code that handles
passwords.  BDE, m$ ODBC etc all handle the passwords though .....

Don't know whether or not password protection was a standard feature,
but
it is not supported by XDB.  Looking at Erik Bachmann's xBase file
format
description at:

http://www.e-bachmann.dk/docs/xbase.htm

I don't see anything about password protection, but there is a field in 
the header for encryption used by dBase IV (and maybe others).  Doesn't
help much, however.  It could be a feature of FoxPro (or whatever they
used to write Act! 2000).

If you come up with more information, I would be interested.

Sorry I couldn't be of more help,

AFAIK, file level password protection was never a feature of
xBase. It certainly has no support in the data structure, nor was
it supported in any of the historic OSs of xBase (CP/M, MS-DOS).
Some xBase apps may have implemented password protection in their
code, but that's not what I hear you asking.

[XDB-users] xBase format with passwords.

[Ashley C. <be...@bi...>]

Hi All,

I am current working on an Act! 2000 clone for Linux and I remember that
someone said the .dbf (dBase) files were a standard xBase format.

The question I have though is that one of these files is password
protected.  I found this out by importing the file into M$ access (it
was the xxxx.ddf file).

I had a look through the code and the docs and I couldn't see any
mention of password support in xBase.  Just wondering if it was a
standard feature of xBase files, and if I am actually on the right track
at all..  (I could be way of base.)

[XDB-users] Usefulness of Xbase/Dbase file format with varying records

[Michael C. <coo...@ma...>]

I am in the planning/early code stages of creating a genealogy program for Linux.  I was already considering using the Dbase file format for my program for the last couple of months and I just saw your library today.  I was, however, planning to change the file format to suit my needs a bit better.

Perhaps someone can help me a bit.  The main problem I am facing is that for each "record" (person in the database),  there will be a large variation in the data stored.  There will be a varying number of events/dates stored for each person.  Ideally, I will copy the good commercial Windows programs by having virtually unlimited number of dates stored for each person.  Second, for each date, there will have to be support for a large number (ideally virtually unlimited) number of source records.  There will also have to be support for a varying number of children for each family with support for large numbers of sets of parents (natural, adopted, step parent, etc) and multiple spouses for
each person.

I hope someone understands what I am trying to say.  Perhaps someone can give me an idea if the Xbase/Dbase/XDB file format and library is capable of being this versitile   If not, could someone give me any idea of how I might be able to go about laying out the file format for this type of database, or any other free/freeware database toolkit/library I could use to create the database format needed in my creation?  I do have an idea how to do it, just not the fine details, especially the index system.  Thanks.
