Hi there,

Know any body if pervasive can work in delphi 2005, what about connection components Pdac ....

Thanks in advance.

PDAC hasn't been released for Delphi 2005. You have several options:
1. Btrieve API
2. ODBC through BDE
3. OLEDB through ADO
4. Managed Provider through ADO.NET (if you use the .NET side of things).

If you really want PDAC for Delphi 2005, call Pervasive and talk to your sales rep.
