读写SQL+ADO的datetime

COleDateTime oleDate = COleDateTime::GetCurrentTime();

_variant_t vtFld;

vtFld.vt = VT_DATE;

vtFld.date = oleDate;

pRecordSet4->PutCollect("date", vtFld);

读时间值

_bstr_t TheValue=m_pset->Fields->GetItem("出生年月")->Value;

temp=(char *)TheValue;

COleVariant vtime(temp);

vtime.ChangeType(VT_DATE);

COleDateTime time4=vtime;//读出的是COleDateTime

用下面的方法转换

COleDateTime time1(1977,4,16,2,2,2); //COleDataTime--->CTime

SYSTEMTIME systime;

VariantTimeToSystemTime(time1, &systime);

CTime tm(systime);
