Sometimes it is not necessary to close connection each time you finish a particular job. For example, suppose you open a form and have to fill several comboboxes. Currently you open and close the connection for each combo, which is clearly a waste of resources. It would be much more efficient to keep the connection open and then close it manually (if we want to). Sometimes keeping a connection open for the whole application's lifesycle is not an issue at all. It would be great to be able to avoid calling the Close method of the DataStore (add an optional bool parameter). Thanks for the great job ulu
