将Unidac 4.0.1与sqlite数据库连接时出错

Question

I'm delphi user, i got problem when try to connect sqlite with my unidac 4.0.1 component. I've dropped TUniConnection , Sqlite uniprovider, setting client library at specification property, but it always raised an error:

file is encrypted or is not database.

I've used - lastest sqlite3.dll - delphi xe - unidac 4.0.1 - sqlite2009 Pro Enterprise (for creating sqlite 3 database file)

Thanks.

Answer 1

I guess you did encrypt the file using Sqlite2009 Pro Enterprise.

The standard sqlite3.dll does not implement encryption.

You'll need either the SQLite Encryption Extension (SEE) , either another implementation (like the one embedded in wxcode ).

If your file is not encrypted, try to use another SQLite3 viewer (like SQLiteSpy or our SynDBExplorer ) to guess if the file is correct.

Also ensure the file is not created in "C:\\Program Files" folder, which is made "virtual" by the UAC.
