Hi Albert,
Does the green line tell you anything if your mouse pointer hovers over it?
Have you tried the following:
Add a reference to System.Data.SQLite by going to Project - Add Reference and choosing System.Data.SQLite?
Then you can add your 'Imports' statement to the top of your class like:
File name is Form1.vb and the contents are as follows:
Imports System.Data.SQLite
Public Class Form1
End Class
Hope that helps.
