mfc把时间转换成秒，然后加上毫秒，

Question

比如，输入2.20.30(2分20秒30)

变成140.30秒

整数会弄，但怎么加上那个.30

最后是double型

谢谢

Answer 1

double CalcTime(LPCTSTR lpszData)
{
	ASSERT(NULL != lpszData);
	double fValue = 0.0;

	TCHAR szHour[16] = {0};
	TCHAR szMinute[16] = {0};
	TCHAR szSecond[16] = {0};
	_stscanf(lpszData, _T("%[0-9].%[0-9].%[0-9]"), szHour, szMinute, szSecond);
	fValue = _ttoi(szHour) * 60 + _ttoi(szMinute) + _ttoi(szSecond) / 100.0;
	return fValue;
}

// 调用
CString strText(_T(""));
strText.Format(_T("%.2f"), CalcTime(_T("2.20.30")));
AfxMessageBox(strText);

Answer 2

_stscanf这个说不安全，我改成了
_stscanf_s

出现这个错误，0x59B93FD4 (msvcr120d.dll) (cacl.exe 中)处有未经处理的异常:  0xC0000005:  写入位置 0x01040000 时发生访问冲突。

不会弄了

Answer 3

_stscanf_s(lpszData, _T("%[0-9].%[0-9].%[0-9]"), szHour, _countof(szHour), szMinute, _countof(szMinute), szSecond, _countof(szSecond));
