// MODULE: appskel.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.
// CmdDLLFunc1 - Calls DLLFunction1() from DLLSKEL.DLL
// CmdDLLFunc2 - Calls DLLFunction2() from DLLSKEL.DLL
//
// COMMENTS:
// Message dispatch table -
// For every message to be handled by the main window procedure
// place the message number and handler function pointer in
// rgmsd (the message dispatch table). Place the prototype
// for the function in globals.h and the definition of the
// function in the appropriate module.
// Command dispatch table -
// For every command to be handled by the main window procedure
// place the command number and handler function pointer in
// rgcmd (the command dispatch table). Place the prototype
// for the function in globals.h and the definition of the
// function in the appropriate module.
// Globals.h Contains the definitions of the structures and dispatch.c
// contains the functions that use these structures.
//
#include <windows.h> // required for all Windows applications
#include <windowsx.h>
#include "globals.h" // prototypes specific to this application
#include "dllskel.h" // prototypes for DLL functions
// Main window message table definition.

// PARAMETERS:
// hwnd - window handle

// 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.
