CMFCToolBar::SetBasicCommands(lstBasicCommands);
// 将文档名和应用程序名称在窗口标题栏上的顺序进行交换。这
// 将改进任务栏的可用性，因为显示的文档名带有缩略图。
ModifyStyle(0, FWS_PREFIXTITLE);
return 0;
}
其中CMFCToolBar::SetBasicCommands(lstBasicCommands);的作用就是开启菜单折叠，并加入不折叠的项。lstBasicCommands参数是菜单的ID列表。注释掉CMFCToolBar::SetBasicCommands(lstBasicCommands);可以关闭自动折叠功能。
MSDN帮助文档解释为打开菜单时，将始终显示的基本命令。
