ID--HANDLE--HWND三者之间的互相转换
id->句柄（由ID得到句柄）-----------hWnd = ::GetDlgItem(hParentWnd,id);
id->指针（由ID得到指针）-----------CWnd::GetDlgItem();
句柄->id（由句柄得到ID）-----------id = GetWindowLong(hWnd,GWL_ID);
句柄->指针（由句柄得到指针）--------CWnd *pWnd=CWnd::FromHandle(hWnd);
指针->ID（由指针得到ID）----------id = GetWindowLong(pWnd->GetSafeHwnd,GWL_ID);
GetDlgCtrlID();
指针->句柄（由 指针得到句柄）--------hWnd=cWnd.GetSafeHandle() or mywnd->m_hWnd;
