// MODULE: generic.c
//
// PURPOSE: Implement the windows procedure for the main application
// windows. Also implement the generic message and command dispatchers.
//
// FUNCTIONS:
// WndProc - Processes messages for the main window.
// MsgCommand - Handle the WM_COMMAND messages for the main window.
// MsgDestroy - Handles the WM_DESTROY message by calling
// PostQuitMessage().
// CmdExit - Handles the file exit command by calling destory
// window on the main window.
//
// COMMENTS:
//
#include <windows.h> // required for all Windows applications
//#include <windowsx.h>
#include "globals.h" // prototypes specific to this application
// Main window message table definition.

// FUNCTION: WndProc(HWND, UINT, WPARAM, LPARAM)
//
// PURPOSE: Processes messages for the main window.
//
// PARAMETERS:
// hwnd - window handle
// uMessage - message number
// wparam - additional information (dependant on message number)
// lparam - additional information (dependant on message number)
//
// RETURN VALUE:
// The return value depends on the message number. If the message
// is implemented in the message dispatch table, the return value is
// the value returned by the message handling function. Otherwise,
// the return value is the value returned by the default window procedure.
//
// COMMENTS:
// Call the DispMessage() function with the main window's message dispatch
// information (msdiMain) and the message specific information.

// PARAMETERS:
// hwnd - window handle
// uMessage - WM_COMMAND (Unused)
// GET_WM_COMMAND_ID(wparam, lparam) - Command identifier
// GET_WM_COMMAND_HWND(wparam, lparam) - Control handle
//
// RETURN VALUE:
// The return value depends on the message number. If the message
// is implemented in the message dispatch table, the return value is
// the value returned by the message handling function. Otherwise,
// the return value is the value returned by the default window procedure.
