如何将Cstring转换为ColeDateTimeSpan？ [英] How to convert Cstring to ColeDateTimeSpan ?

问题描述

COleDateTimeSpan dtOleDuration;

CString m_sDuration;



这里我有两个不同类型的变量现在我想将CString转换为ColeDateTimeSpan



此持续时间介于批次/节点的startdate和enddate之间

COleDateTimeSpan dtOleDuration;
CString m_sDuration;

here iam having two variables which is of different types now i want convert CString to ColeDateTimeSpan

this duration is between startdate and enddate of a batch / node

推荐答案

您需要转换字符串为整数并使用该整数来设置 ColeDateTimeSpan 变量，根据其定义。

You need to convert the string to an integer and use that integer to set the ColeDateTimeSpan variable, according to its definition.

根据上面的评论你似乎有一个时间跨度字符串格式为hh：mm：ss。然后你可以这样执行转换：

According to the above comments you seem to have a time span string in the format hh:mm:ss. Then you can perform the conversion like this:

// Convert time span string to COleDateTimeSpan
// Format must be [[hh:]mm:]ss[.msec]
COleDateTimeSpan SpanFromString(const CString& strSpan) const
{
	long lDays = 0;
	long lHours = 0;
	int nMins = 0;
	int nSecs = 0;
	LPCTSTR s1 = strSpan.GetString();
	LPCTSTR s2 = _tcschr(s1, _T(':'));
	LPCTSTR s3 = s2 ? _tcschr(s2 + 1, _T(':')) : NULL;
	// hh:mm:ss
	if (s3)
	{
		nSecs = _tstoi(s3 + 1);
		nMins = _tstoi(s2 + 1);
		lHours = _tstol(s1);
	}
	// mm:ss
	else if (s2)
	{
		nSecs = _tstoi(s2 + 1);
		nMins = _tstoi(s1);
	}
	// ss or empty string
	else
		nSecs = _tstoi(s1);
	if (lHours >= 24)
	{
		lDays = lHours / 24;
		lHours %= 24;
	}
	return COleDateTimeSpan(lDays, (int)lHours, nMins, nSecs);
}
