DLL usage issue

[kornicameister]

I wanted to test my dll by creating simple console application
application is linked successfully, headers are visible but application does not start...
it is becoming more weird as application starts when these lines are commented

27. data = new SettingData(tmp,0);
33. data->addOption(SD::ATTRIBUTE_NAME,tmp);
34. data->addOption(SD::REFERER,i+j);
41. cout << "Table name ->" << d->name() << endl;

27. data = new SettingData(tmp,0);
33. data->addOption(SD::ATTRIBUTE_NAME,tmp);
34. data->addOption(SD::REFERER,i+j);
41. cout << "Table name ->" << d->name() << endl;

To copy to clipboard, switch view to plain text mode 

but making only one of them not commented results in successful build but applications exists with code 0 right after start

and SettingData is one of the class that can be found in dll library.

[here is whole code]

#include <QtCore/QCoreApplication>
#include "data/settingdata.h"
#include <iostream>
#include <QStack>
#include <QString>
 
using namespace std;
 
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    quint16 tableCount = 0,columnCount = 0,referer = 0;
    string tableName = "", columnName = "";
    QStack<SettingData*> dataStack;
    SettingData *data;
 
    QString tmp = QString::null;
 
    cout << "Test application for xml processing in AgatomProject" << endl;
    cout << "Tables count -> "; cin >> tableCount;
 
    for(quint16 i = 0 ; i < tableCount ; i++){
        cout << "Table " << i+1 << " name -> "; cin >> tableName;
        cout << "How many columns -> "; cin >> columnCount;
 
        tmp.fromStdString(tableName);
//        data = new SettingData(tmp,0);
 
        for(quint16 j = 0 ; j < columnCount ; j++){
            cout << "Enter " << j+1 << " column name for " << tableName << " table -> "; cin >> columnName;
            cout << "Referef will be set to " << referer++ << endl;
            tmp.fromStdString(columnName);/*
            data->addOption(SD::ATTRIBUTE_NAME,tmp);
            data->addOption(SD::REFERER,i+j);*/
        }
        dataStack.push(data);
    }
 
    cout << "Adding data finished, control output" << endl;
    foreach(SettingData *d, dataStack){
//        cout << "Table name ->" << d->name() << endl;
    }
 
    return a.exec();
}

#include <QtCore/QCoreApplication>
#include "data/settingdata.h"
#include <iostream>
#include <QStack>
#include <QString>

using namespace std;

        cout << "How many columns -> "; cin >> columnCount;

        tmp.fromStdString(tableName);
//        data = new SettingData(tmp,0);

        for(quint16 j = 0 ; j < columnCount ; j++){
            cout << "Enter " << j+1 << " column name for " << tableName << " table -> "; cin >> columnName;
            cout << "Referef will be set to " << referer++ << endl;
            tmp.fromStdString(columnName);/*
            data->addOption(SD::ATTRIBUTE_NAME,tmp);
            data->addOption(SD::REFERER,i+j);*/
        }
        dataStack.push(data);
    }

    cout << "Adding data finished, control output" << endl;
    foreach(SettingData *d, dataStack){
//        cout << "Table name ->" << d->name() << endl;
    }

    return a.exec();
}

does your app give any error message? make sure you placed your .dll nearby your exe.

The attached file is a working sample of a .dll usage:
test4.zip
MyDynLibrary.zip

Yeah, you're right
I just forgot to put dll into exe location, therefore I could not make my application launch.

My mistake...pretty embarrassing ;-)
