删除MFC自建的单文档工程的菜单和工具栏

1.去除菜单

        在CMainFrame::PreCreateWindow(CREATESTRUCT& cs)函数中加入一句：

         cs.hMenu = NULL;

2.去除工具栏

         在CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)中注释掉一些语句。

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
 if (CFrameWnd::OnCreate(lpCreateStruct) == -1)
  return -1;
 
 //if (!m_wndToolBar.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP
 // | CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) ||
 // !m_wndToolBar.LoadToolBar(IDR_MAINFRAME))
 //{
 // TRACE0("Failed to create toolbar\n");
 // return -1;      // fail to create
 //}

 if (!m_wndStatusBar.Create(this) ||
  !m_wndStatusBar.SetIndicators(indicators,
    sizeof(indicators)/sizeof(UINT)))
 {
  TRACE0("Failed to create status bar\n");
  return -1;      // fail to create
 }

 // TODO: Delete these three lines if you don't want the toolbar to be dockable
 //m_wndToolBar.EnableDocking(CBRS_ALIGN_ANY);
 //EnableDocking(CBRS_ALIGN_ANY);
 //DockControlBar(&m_wndToolBar);
 
 return 0;
}
