CMonthCalCtl::GetCurSel(CTime)不能返回正确日期？

SYMPTOMSWhen you use the CMonthCalCtrl::GetCurSel(CTime) to get the date selected from the Month Calendar Common control, the date in the CTime class is incorrect. CAUSEMFC's implementation of CMonthCalCtrl::GetCurSel() for the CTime class calls SendMessage(MCM_GETCURSEL, &sysTime) where sysTime is a SYSTEMTIME structure. The MCM_GETCURSEL message does not fill in the hours, minutes, and seconds part of the sysTime Structure with valid values. However, the constructor for CTime class takes these values into consideration, so the date in CTime class is incorrect. RESOLUTIONThe workaround is to use the CMonthCalCtrl::GetCurSel(SYSTEMTIME*) version of GetCurSel for this class to get the correct date. The code will look like the following example: SYSTEMTIME sysTime; m_MonthCal.GetCurSel(&sysTime); sysTime.wHour = sysTime.wMinute = sysTime.wSecond = sysTime.wMilliseconds = 0; CTime l_time(sysTime);
