我正在使用 boost 库来获取当前系统时间并且我的代码可以工作,但是在程序之后 Visualt Studio 2010 退出。调试器在尝试释放不存在的指针时中断。我知道这是因为 boost 本机代码。因为如果我评论代码的 boost 部分没有错误。
直到现在我尝试使用 MSDN 中解释的#pragma 但没有成功。有人可以给我一些建议吗?(我也尝试了 GetSystemTime 函数来获取时间,但我无法获得像 boost 这样的微秒细节。)
我的代码
#pragma managed(push, off)
void GetSystemDateTime(SDateTime& stimeblock);
#pragma managed(pop)
int main()
{
c++/cli code
SDateTime stimestruct[1];
//call to the function having the boost code..
GetSystemDateTime(stimestruct[0]);
}
功能定义
#pragma managed(push, off)
void GetSystemDateTime(SDateTime& timeblock)
{
// SYSTEMTIME time;
// GetSystemTime(&time);
// WORD millis = (time.wSecond * 1000) + time.wMilliseconds;
boost::posix_time::ptime now = boost::posix_time::microsec_clock::local_time();
std::tm pt_tm = to_tm(now);
std::cout << now << std::endl;
//std::cout << time.wYear<< time.wMonth<<time.wDay //<<time.wHour<<time.wMinute<<time.wSecond<<time.wMilliseconds << std::endl;
std::string timestring = to_iso_string(now);
std::string sYear = timestring.substr (0,4);
std::string sMonth = timestring.substr (4,2);
std::string sDay = timestring.substr (6,2);
std::string sHour = timestring.substr (9,2);
std::string sMinute = timestring.substr (11,2);
std::string sSecond = timestring.substr (13,2);
std::string sUSecond = timestring.substr (16);
istringstream isYear(sYear);
istringstream isMonth(sMonth);
istringstream isDay(sDay);
istringstream isHour(sHour);
istringstream isMinute(sMinute);
istringstream isSec(sSecond);
istringstream isUSec(sUSecond);
// use is like an input stream
int iYear,iMonth,iDay,iHour,iMinute,iSecond,iUSecond;
isYear >> iYear;
isMonth >>iMonth;
isDay >>iDay;
isHour >>iHour;
isMinute >>iMinute;
isSec >>iSecond;
isUSec >>iUSecond;
timeblock.uiYear = iYear;
timeblock.usiMonth = time.wMonth;
timeblock.usiDay = time.wDay;
timeblock.usiHour = time.wHour;
timeblock.usiMinute = time.wMinute;
timeblock.usiSec = time.wSecond;
timeblock.udiUSec = time.wMilliseconds;
