Direct Link to old btrieve Database files from VB6

[Guest_imported]

Hello !

I'm using VB6
I want to directly link to an old btrieve 6.15 database file and read or modify it's data. another old application is using this file too, so I can't convert it to a new format...

thanks.

One thing you might try to do is look for the developers kit. I've never gone this route myself, but instead of using SQL you can go the Index Sequential route (a bit like the old COBOL files).

6.15 is fairly old but I'm sure there was a developers kit for that version - it's just getting a copy might be tricky.

You need to get the PERVASIVE ODBC Updates, and once U install the same on the server where the Btr files reside...all you need to do is create a Pervasive Engine DSN ... from the "Control Panel--ODBC" on the same machine.

After that Install the Pervasive ODBC client on the machine where you want to access your data from(I mean the client machine). Then go to the Control Panel-ODBC and then define a "Pervasive Client DSN", and point it to the new Engine DSN you just crested on the server...its easy beleive me... No use the new Client DSN as you would be using a normal ODBR DSN

One good thing about Btrieve / Pervasive files - the newer requesters will work with the older files.

Go to

http://www.Pervasive.com

and download a trial SDK version. The drivers installed by this (especially the ADO driver) will allow for access to the older Btrieve 6.15 files - if you have correct DDF files. If you don't, you will have to use direct BTrieve calls to access them, which is much more difficult (but still doable) in VB.

NOTE: If you are also registered at Novell as a developer (free registration), you can download a full working copy of the Pervasive SDK to work with, instead of a trial version.
