对话框中的check消息响应以及Toolbar加载

在对话框中加载菜单时，菜单上的check是无法实现了。这是无法更新UI所导致的。
因此必须手动添加以下代码

void CVRMineDlg::OnInitMenuPopup(CMenu *pPopupMenu, UINT nIndex,BOOL bSysMenu)
{
  //增加此消息映射，使基于对话框的菜单能够使用ON_UPDATE_COMMAND_UI更新菜单
    ASSERT(pPopupMenu != NULL);
    // Check the enabled state of various menu items.

    CCmdUI state;
    state.m_pMenu = pPopupMenu;
    ASSERT(state.m_pOther == NULL);
    ASSERT(state.m_pParentMenu == NULL);

    // Determine if menu is popup in top-level menu and set m_pOther to
    // it if so (m_pParentMenu == NULL indicates that it is secondary popup).
    HMENU hParentMenu;
    if (AfxGetThreadState()->m_hTrackingMenu == pPopupMenu->m_hMenu)
        state.m_pParentMenu = pPopupMenu;    // Parent == child for tracking popup.
    else if ((hParentMenu = ::GetMenu(m_hWnd)) != NULL)
    {
        CWnd* pParent = this;
           // Child windows don't have menus--need to go to the top!
        if (pParent != NULL &&
           (hParentMenu = ::GetMenu(pParent->m_hWnd)) != NULL)
        {
           int nIndexMax = ::GetMenuItemCount(hParentMenu);
           for (int nIndex = 0; nIndex < nIndexMax; nIndex++)
           {
            if (::GetSubMenu(hParentMenu, nIndex) == pPopupMenu->m_hMenu)
            {
                // When popup is found, m_pParentMenu is containing menu.
                state.m_pParentMenu = CMenu::FromHandle(hParentMenu);
                break;
            }
           }
        }
    }

    state.m_nIndexMax = pPopupMenu->GetMenuItemCount();
    for (state.m_nIndex = 0; state.m_nIndex < state.m_nIndexMax;
      state.m_nIndex++)
    {
        state.m_nID = pPopupMenu->GetMenuItemID(state.m_nIndex);
        if (state.m_nID == 0)
           continue; // Menu separator or invalid cmd - ignore it.

        ASSERT(state.m_pOther == NULL);
        ASSERT(state.m_pMenu != NULL);
        if (state.m_nID == (UINT)-1)
        {
           // Possibly a popup menu, route to first item of that popup.
           state.m_pSubMenu = pPopupMenu->GetSubMenu(state.m_nIndex);
           if (state.m_pSubMenu == NULL ||
            (state.m_nID = state.m_pSubMenu->GetMenuItemID(0)) == 0 ||
            state.m_nID == (UINT)-1)
           {
            continue;       // First item of popup can't be routed to.
           }
           state.DoUpdate(this, TRUE);   // Popups are never auto disabled.
        }
        else
        {
           // Normal menu item.
           // Auto enable/disable if frame window has m_bAutoMenuEnable
           // set and command is _not_ a system command.
           state.m_pSubMenu = NULL;
           state.DoUpdate(this, FALSE);
        }

        // Adjust for menu deletions and additions.
        UINT nCount = pPopupMenu->GetMenuItemCount();
        if (nCount < state.m_nIndexMax)
        {
           state.m_nIndex -= (state.m_nIndexMax - nCount);
           while (state.m_nIndex < nCount &&
            pPopupMenu->GetMenuItemID(state.m_nIndex) == state.m_nID)
           {
            state.m_nIndex++;
           }
        }
        state.m_nIndexMax = nCount;
    }
}


关于在对话框中增加toolbar，有点麻烦，
toolbar不能floating，也不能docking，也不能自动实现两个toolbar并排放在一起。
除非自己再把代码改一下。
我暂时没有找到很好的解决办法。
m_wndToolBar.Create(this); m_wndToolBar.LoadToolBar(IDR_TOOLBAR1); m_wndToolBar.ShowWindow(SW_SHOW); m_wndToolBar.SetBarStyle(CBRS_ALIGN_TOP | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC); RepositionBars(AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0);
