寫入時間值
COleDateTime oleDate = COleDateTime::GetCurrentTime();
_variant_t vtFld;
vtFld.vt = VT_DATE;
vtFld.date =
oleDate;
pRecordSet4-> PutCollect( "date ", vtFld);
關于時間類型的幾種轉換
strCString= "2003-10-27 6:24:37 "; //CString--->
COleDateTime
COleVariant vtime(strCString);
vtime.ChangeType(VT_DATE);
COleDateTime time4=vtime;
COleDateTime time1(1977,4,16,2,2,2); //COleDataTime---> CTime
SYSTEMTIME systime;
VariantTimeToSystemTime(time1,
&systime);
CTime tm(systime);
time_t
time2=tm.GetTime(); //CTime---> time_t
COleDateTime
time3(time2); //time_t---> COleDateTime
