SQLite supports several datatypes: NULL for empty, INTEGER and REAL for signed integers and floating point values respectively, TEXT for text strings, and BLOB for binary files.

XnView uses an SQLite database for storing this info and accessing it; Windows uses a flat file for the image metadata and another for the actual image thumbnails.

I've got it in a sub-folder, and the data source has a hard-coded path to the db file. How can I make it relative? For a WebApp, I'd rely on Server.MapPath, but how to do something similar here?
