Questionc++ exporting class variables Pin

Memberbfis1081371-Jun-13 9:26 
I am very very new to c++. I have been allowed lol to be a part of this c++ project. I am supposed to write a c++ dll that will export to c#. Anyways I am having trouble with class variables in functions that are exported. Could someone help me pleaser with this. Fyi we are using qt framework so that's why you see a few qt things. Basically it is crashing if I access a class variable which in this case is called testInt. this is not the actual code we are working with but it does duplicate the problem exactly as it occurs in the real code. The problem is my c# code crashes when the variable testInt is accessed but not if testInt2 is accessed.

header
#ifndef QTDDLLTESTCLASSVARIABLE_H
#define QTDDLLTESTCLASSVARIABLE_H

#include "qtddlltestclassvariable_global.h"

class QTDDLLTESTCLASSVARIABLE_EXPORT qtdDllTestClassVariable
{
public:
	qtdDllTestClassVariable();
	~qtdDllTestClassVariable();
	void Test();
	int testInt;
private:

};

#endif // QTDDLLTESTCLASSVARIABLE_H


#include "qtddlltestclassvariable.h"
#include <qDebug>

cpp file
qtdDllTestClassVariable::qtdDllTestClassVariable()
{

}

qtdDllTestClassVariable::~qtdDllTestClassVariable()
{

}

void qtdDllTestClassVariable::Test()
{
	qDebug() << "started";
	testInt = 5;
	int testInt2 = 5;
        qDebug() << testInt << " after int";
	qDebug() << testInt2 << " after int2";
}



c# code

[DllImport(@"..\..\..\Win32\Debug\qtdDllTestClassVariable.dll", CharSet = CharSet.Unicode, EntryPoint = "?Test@qtdDllTestClassVariable@@QAEXXZ")]
        public static extern void Test();
