Default way to access btrieve files without ddf - 06-08-2004 , 08:29 AM






Hello.
As I wrote in topic I'm looking for any programmer's methods to access
to btrieve files without ddf's. I have got these files but I dont want
to share it with clients. Limiting perrmissions isn't the best idea. Is
there any way to insert description of ddf files into component or
programmer's code? The best way will be if I automaticaly insert ddf
definitions into component (like o some component property). I found
Btrieve API in SDK from Pervasive V8 SDK but I can't define keys, fields
and other which are in ddf files.

bye...

High level - You can access btrieve files without DDF's with Delphi and
Titan, using Titan's compiled resources. But this works only for
transactional access. If you require relational (SQL) access, I'm afraid
you will have to share your secrets with your clients.

Low level - Btrieve API - You don't need DDF's at all!

Yes I know but I'm try do import definitions from ddf files into Btrieve
API and I have real problem with it. Is there any util which could help
me with import data from ddf files into Btrieve API procedures?

The Btrieve API does not use DDF's. You must write your own code to
interpret the data, unless you use the ActiveX controls or other
higher-level construct.

I remember hearing about a utility that could convert the DDFs into c
structure definitions if I remember correctly.
Actually I found one in the Pervasive ComponentZone.
