With Btrieve 6.15, you'll need the Win32 client on the WInNT 4.0 system. The only reliable way to access data with Btrieve 6.15 was with the Btrieve API. If you've got a Btrieve 6.15 SDK, you'll have
VB 4.0 sample code that will also work in
VB 6.0.
That being said, I would suggest upgrading to Pervasive.SQL V8. It's the current version of Btrieve, is still supported by Pervasive (while Btrieve 6.15 isn't), and has an SDK that has a number of access methods including ODBC, the Btrieve API, ActiveX, and OLEDB.
There's also a white paper on accessing Pervasive from
VB on Pervasive's web site (
http://www.pervasive.com/documentati...Whitepaper.pdf).
