Some users might need to add the following link: Configuration and setting the appropriate properties. Either set the Active property of the dataset to True, at design time in the Object Inspector or in code at runtime CustTable.

If Java classes all had property lists, it would still be a small-scale instantiation of the Properties pattern, but it would open up an awful lot of new design possibilities to Java programmers. To connect and execute a query manually, you would normally write something like the - A lightweight performance wrapper library for working with SQLite including usage examples in C# & VB.
