关于类型转化

Question

如何进行
time与systemtime,
time与char,
time与CString之间的类型转化呢?

Answer 1

时间转为字符串：
1
CString str;
CTime t = CTime::GetCurrentTime();
str.Format("%d-%d-%d",t.GetYear(),t.GetMonth(),t.GetDay());
2
CString strTime;
CTime tTime = CTime::GetCurrentTime();
strTime = tTime.Format("%Y-%m-%d %H:%M:%S");

Answer 3

那我有字符串"2003-10-27 6:24:37"
如何把他转换为SYSTEMTIME类型呢

Answer 4

strCString="2003-10-27 6:24:37";  
COleVariant vtime(strCString);
vtime.ChangeType(VT_DATE);
COleDateTime time4=vtime;//先把CString类型转为COleDateTime
再把COleDateTime转为SYSTEMTIME
COleDateTime time1;
SYSTEMTIME systime;
VariantTimeToSystemTime(time1,&systime);

Answer 5

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
