标题：请教 date类型怎样能转换成time_t类型呢？

1楼

就是

//读取上海市场的600000日线数据范例
PCALCINFO stData = {0};
stData.m_dataType = MIN5_DATA;//日线
stData.m_bIsPow = 1; //是否复权
stData.m_wMarket = 'JZ';

之中的stData.m_pMainData[i].m_timeDate，m_timeDate原先定义应该是date格式，要转成time_t格式

给你一个我们的自用转换函数

CTime COleDataTimeToCTime(COleDateTime& time)
{
CTime time2(time.GetYear(),time.GetMonth(),time.GetDay(),time.GetHour(),time.GetMinute(),time.GetSecond());
return time2;
}

使用范例:

time_t timeDate = COleDataTimeToCTime(stData.m_pMainData[i].m_timeDate).GetTime();

出错啊

Compiling...
MainWindowDlg.cpp
E:\AddinDemo\MainWindowDlg.cpp(256) : error C2664: 'COleDataTimeToCTime' : cannot convert parameter 1 from 'double' to 'class COleDateTime &'
A reference that is not to 'const' cannot be bound to a non-lvalue
E:\AddinDemo\MainWindowDlg.cpp(256) : error C2228: left of '.GetTime' must have class/struct/union type
执行 cl.exe 时出错.

是不是函数的位置没放对，应该放在哪里呢

COleDateTime timeTemp = stData.m_pMainData[i].m_timeDate;

time_t timeDate = COleDataTimeToCTime(timeTemp ).GetTime();

这样转化一下
