                      4: *  In this sample the main window is a dialog box.  There is no need to
                      5: *   register a new window class or create a new window.  Instead just call
                      6: *   DialogBox() and use the template defined in the .RC file.  All of the
                      7: *   interesting code is thus in the window procedure for the dialog box.
                      8: *   In this case, simply respond to the combobox command messsages and fill
                      9: *   the list box with appropriate values.
