Registration
============

Please be sure to fill out the registration form, REGISTER.TXT, and
return it to Daytris.  This will ensure proper notification of
CDB For Windows upgrades.


Zortech C/C++ Compiler
======================

If you wish to recompile the SAMPLE program, define ZORTECH in the
compile options on the command line.  The only difference is the
memory.h include file.  Zortech C doesn't have one, the _fmem
functions are included in string.h.


C & Visual Basic Incompatibilities
==================================

The two sample programs, SAMPLE.EXE and VBSAMPLE.EXE, cannot access
the same database.  This is because of the differences between C strings
and Visual Basic strings.  C strings are NULL terminated.  Visual Basic
strings are space filled with no NULL terminating character.  This
creates incompatibilities in like structures.

The VBSAMPLE.EXE program may terminate with a UAE (uninterruptable
application error) when accessing a database created with SAMPLE.EXE.
This is due to the string incompatibilities described above.


Visual Basic Notes
==================

Before running the CDBW sample applications, copy both DBSERVER.EXE and
DBTALK.DLL to your WINDOWS directory or a directory in your path.

The DbOpen call in MENU.FRM contains a hardcoded directory of where the
data base files reside.  This is the directory where the .DAT and .KEY
files will be created.  The .DBD file must also reside in this directory.
