隐藏菜单栏


//单击处理函数
void CHideMenuBarView::OnLButtonDown(UINT nFlags, CPoint point) 
{
//隐藏菜单栏
::SetMenu(AfxGetMainWnd()->m_hWnd, NULL);
CView::OnLButtonDown(nFlags, point);
}
//右击处理函数
void CHideMenuBarView::OnRButtonDown(UINT nFlags, CPoint point) 
{
//显示菜单栏
CMenu menu;
menu.LoadMenu(IDR_MAINFRAME); //加载菜单
HMENU hMenu = (HMENU)menu; //类型转换
::SetMenu(AfxGetMainWnd()->m_hWnd, hMenu); //设置菜单
CView::OnRButtonDown(nFlags, point);
}






隐藏和显示状态栏


void CMainFrame::OnShow() 
{
//判断是否状态栏可见
if(!m_wndStatusBar.IsWindowVisible())
{
//如果是不可见的，设置为可见
m_wndStatusBar.ModifyStyle(0, WS_VISIBLE);
}
//使状态栏状态生效
    SendMessage(WM_SIZE);
}


void CMainFrame::OnHide() 
{
//判断是否状态栏可见
if(m_wndStatusBar.IsWindowVisible())
{
//如果是可见，设置为隐藏
m_wndStatusBar.ModifyStyle(WS_VISIBLE, 0);
}
//使状态栏状态生效
SendMessage(WM_SIZE);
}












隐藏和显示标题栏


void CMainFrame::OnMenuShowtitlebar() 
{
LONG style = GetWindowLong(m_hWnd, GWL_STYLE); //得到窗口类型
    style |= WS_CAPTION; //修改窗口类型，显示标题栏
    SetWindowLong(m_hWnd, GWL_STYLE, style); //设置窗口类型


//移动窗口使显示标题栏立即生效
    RECT winRect;
    GetWindowRect(&winRect);//得到窗口位置
    winRect.top--; //窗口下移
    MoveWindow(&winRect); //移动窗口
}


void CMainFrame::OnMenuHidetitlebar() 
{
LONG style = GetWindowLong(m_hWnd, GWL_STYLE); //得到窗口类型
    style &= ~(WS_CAPTION); //修改窗口类型，显示标题栏
    SetWindowLong(m_hWnd, GWL_STYLE, style); //设置窗口类型

//移动窗口使隐藏标题栏立即生效
    RECT winRect;
    GetWindowRect(&winRect);//得到窗口位置
    winRect.top++; //窗口上移
    MoveWindow(&winRect); //移动窗口
}








给菜多文档单选项前面添加位图




BOOL CIconMenuMDIDoc::OnNewDocument()
{
if (!CDocument::OnNewDocument())
return FALSE;


// TODO: add reinitialization code here
// (SDI documents will reuse this document)
m_bitmap.LoadBitmap(IDB_BITMAP1);
    
    CMenu *pMenu;
    pMenu = CMenu::FromHandle(((CMultiDocTemplate *)m_pDocTemplate)->m_hMenuShared); // 获得文档菜单
//给菜单 文件->新建 添加图标
    pMenu->GetSubMenu(0)->SetMenuItemBitmaps(0, MF_BYPOSITION, &m_bitmap, &m_bitmap);
    return TRUE;
}






给菜半单文档单选项前面添加位图


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

!m_wndToolBar.LoadToolBar(IDR_MAINFRAME))
{

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);


bitmap.LoadBitmap(IDB_BITMAP1);//加载位图

//给菜单 文件->新建 添加图标
GetMenu()->GetSubMenu(0)->SetMenuItemBitmaps(0, MF_BYPOSITION, &bitmap, &bitmap);
return 0;
}
