Demo4 shows how user settings can be stored in a table and selectively retrieved at will.
I made a class TDataList for the sake those who do not have Delphi Professional of Delphi Enterprise. It is meant to take the place of a table class. It contains the two "fields" Login and XML. In a real table, XML would be a memo field.
The application saves the settings in XML format into the memo field.
This is the only demo where the application knows what type of storage object it's using. This is so that it can get to the XML document when posting or fetching the settings from the table.
