/* Main Window Procedure */
/* */
/* This procedure provides service routines for the Windows events */
/* (messages) that Windows sends to the window, as well as the user */
/* initiated events (messages) that are generated when the user selects */
/* the action bar and pulldown menu controls or the corresponding */
/* keyboard accelerators. */
/* */
/* The SWITCH statement shown below distributes the window messages to */
/* the respective message service routines, which are set apart by the */
/* CASE statements. The window procedures must provide an appropriate */
/* service routine for its end user initiated messages, as well as the */
/* general Windows messages (ie. WM_CLOSE message). If a message is */
/* sent to this procedure for which there is no programmed CASE clause */
/* (i.e., no service routine), the message is defaulted to the */
/* DefWindowProc function, where it is handled by Windows */
/* */
/* For the end-user initiated messages, this procedure is concerned */
/* principally with the WM_COMMAND message. The menu control ID (or the */
/* corresponding accelerator ID) is communicated to this procedure in */
/* the first message parameter (wParam). The window procedure provides */
/* a major CASE statement for the WM_COMMAND message and a subordinate */
/* SWITCH statement to provide CASE clauses for the message service */
/* routines for the various menu item's, identified by their ID values. */
/* */
/* The message service routines for the individual menu items are the */
/* main work points in the program. These service routines contain the */
/* units of work performed when the end user select one of the menu */
/* controls. The required application response to a menu control is */
/* programmed in its associated CASE clause. The service routines may */
/* contain subroutine calls to separately compiled and libraried */
/* routines, in-line calls to subroutines to be embodied in this source */
/* code module, or program statements entered directly in the CASE */
/* clauses. Program control is switched to the appropriate service */
/* routine when Windows recognizes the end user event and sends a WM_COMMAND */
/* message to the window procedure. The service routine provides the */
/* appropriate application-specific response to the end user initiated */
/* event, then breaks to return control to the WinMain() routine which */
/* continues to service the message queue of the window(s). */
