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);
