dialog window will present a (possibly) scrolling list of values
that come from a data table source. Based on the object type passed
in the constructor, a ListBox is built to present the user with a
single selection listbox.
The string selected from the list box is stored in the Global variable

For each object (database) type that is to be used, an overridden
