Week 11 project

Add file I/O and dialog boxes to a previous project: the grader, slide show, rainfall simulator, name sorter. 

1.  In grader, add a button to fill names/grades arrays from a file.  Add a button to save array contents to a file.  Use dialog box for the file name. (easy to medium difficulty)

2. In rainfall simulator, add a button to get rainfall data from a file and add a save button to save rainfall data to a file. (easy to medium difficulty)

3.  Fill a file with names of bmp, gif and/or jpg files.  Provide an input file dialog for the user. Read the names from the file into your picture array array.  Now, display names in a combobox or combine with the random picture project OR combine with the timer project to display changing/moving pictures. (easy difficulty level)

4.  Provide a form with listbox, open, save, add and sort buttons. Let the user enter names into the listbox using a textbox and the add button (as in one of your previous projects). The open/save buttons should open dialog boxes and allow the user to load a list of names from a file into your listbox or save your listbox words to a file. The sort button should sort names and displays the sorted list. Be sure to adjust/check that your sorting works properly for strings (not numbers). (You will have to modify the comparison code to use compareTo() function rather than > symbol.) (medium difficulty)
