CDateTimeUI Xp下的bug修复

CDateTimeUI 的bug修复。修改CDateTimeWnd的HandleMessage方法

if(WM_NOTIFY==uMsg)
{
    ::SetFocus(m_hWnd);
}
if( uMsg == WM_KILLFOCUS /**/)
{
      ::OutputDebugString("WM_KILLFOCUS\n");
      if( uMsg == WM_KILLFOCUS /**/)
       {
            //这里肯可能需要优化，因为FindWindow找出来的窗口不一定是本进程的窗口
            HWND hh=::FindWindow(_T("SysMonthCal32"),NULL);
            if(::IsWindow(hh))
            {
                 MCHITTESTINFO pp;
                 memset(&pp,0,sizeof(pp));
                 //pp.uHit=MCHT_CALENDAR;
                 GetCursorPos(&pp.pt);
                 ::ScreenToClient(hh,&pp.pt);
                 pp.cbSize=sizeof(pp);
                 MonthCal_HitTest(hh,&pp);
                 //下一个月
                 if(pp.uHit==MCHT_TITLEBTNNEXT)
                 {
                     return 1;
                 }
                 //上一个月
                 if(pp.uHit==MCHT_TITLEBTNPREV)
                 {
                     return 1;
                 }
            }else{
                POINT pt;
                ::GetCursorPos(&pt); 
                RECT rt;
                ::GetWindowRect(m_hWnd,&rt);
