(Note: The base code is already written, I just need help modifying it in order to add a combo box that shows and allows the user to select a table from the query.)

(here is the code)

Figure 32.30b You can select a table from the combo box to display its contents in the text area. Use the Access database exampleMDB.db, a SQLight database for this exercise.
