//
//  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.
//    CmdDemo      - Displays the "Demo" dialog box
//

//  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.
