Hello,

I came across strange problem with Settings::instance().evaluationDate() when I am exposing it to .NET environment. (QuantLib - > Managed C++ - > C#).

In this case, I am catching exception such as "The exception unknown software exception (0x0020001) occurred in the application". This exception only happends when I call Settings::instance().evaluationDate(). I tested other classes/functions such as Date and some mathematical functions. As long as they not calling Settings::instance().evaluationDate() everything is working. I am bit puzzled because I do not understand this exeption.

Thank you,
Boris.

Below is a simple c++ code:

.....
class TestSettings
{
public:
    void test();
};
....

void TestSettings::test()
{
 
    Date todaysDate = Date::todaysDate();
    Settings::instance().evaluationDate() = todaysDate;
}



Below is a simple Managed c++ code:


#pragma once

#include <export/testsettings.hpp>

using namespace System;
//_________________________________________
namespace Wrapper
{
//____________________________________________
public ref class TestSettingsManaged
{
private:
    TestSettings *ptr;

public:
    TestSettingsManaged(void);

    !TestSettingsManaged();
    ~TestSettingsManaged();

    void testManaged();
};



#include "StdAfx.h"
#include "TestSettingsManaged.hpp"

namespace Wrapper
{
//__________________________________________________
TestSettingsManaged::TestSettingsManaged(void)
{
    ptr = new TestSettings();
}
//__________________________________________________
TestSettingsManaged::!TestSettingsManaged()
{
    delete ptr;
}
//__________________________________________________
TestSettingsManaged::~TestSettingsManaged()
{
    this->!TestSettingsManaged();
}
//__________________________________________________
void TestSettingsManaged::testManaged()
{   
    ptr->test();
}
//__________________________________________________
}

And finally console C# console application

using System;
using Wrapper;

namespace WrapperTest
{
    class Program
    {
       static void Main(string[] args)
        {
          TestSettingsManaged setting = new TestSettingsManaged();
          setting.testManaged();
       }
   }
}
