with this method you can create a new connection to a database. If no driver is set a dialog appears which asks for the driver. You can set a GUI dependend driverdialog with set_driverselectdialog.

Parameters:

	drivername	name of the wished database driver (i.e. mysql)
	i	if i is set to 'interactive' warningmessages and dialog boxes will be shown

Returns:

a driver specific version of hk_connection or NULL if no driver could be found.

hk_connection * hk_drivermanager::find_existing_connection	(	const hk_string &	drivername,
		const hk_string &	host,
		unsigned int	tcp_port,
		const hk_string &	user
	)

If an already created connection exists, it will be returned otherwise NULL
