In the SQLite3.Close method, be sure to null out of the _sql field when _ownHandle is false. Centralize the SQLite3 instance creation logic used by the SQLiteConnection class. Restrict the ConnectionStringBuilder test to run only when SQLite is in use. check-in: 67f779810e user: mistachkin tags: virtualTables

Correct vtable related maximum memory allocation calculation. Also, always use a lock statement for better portability to the .NET Compact Framework. check-in: 33eaa98450 user: mistachkin tags: virtualTables
