[logins]
size=0regards

If you have @QList<Login> m_logins@ member in your MainWindow class, and if in read function you'll use m_logins.append, I'm sure that write function will write in ini file as many Login as you appended before.
-
No cincirin..I coded the 2 functions according to your suggestions..but its not entering the loop in the savesettings function..and everytime it says size=0;//
so i think on click of a button we shouls set the username and passwd..
this way..
@void MainWindow::on_set_clicked()
{login.userName=ui->lineEdit->text(); login.password=ui->lineEdit_2->text(); logins.append(login);
}@
i dont know whether i m right or wrong..u please just check out//

Ok, in the following code if you call Test::count function, you'll see as many Login as you appended:
@
class Test
{
public:
void append();
int count()const;protected:
struct Login
{
QString userName;
QString password;
};QList<Login> m_loginsList;
};
void Test::append()
{
Login log = {"user", "pwd"};
m_loginsList.append(log);
}int Test::count()const
{
return m_loginsList.size();
}int main(int argc, char *argv[])
{
Test t;
t.append(); // one item
t.append(); // two items
// ...
qDebug("%d", t.count()); // print how many items are in list
return 0;
}

ok.thanks..so whether my code is correct..?
hey now my ini file is showing..the data which i input through the lineedit..but the username and password are not appending in the list..I mean the next time when i run and enter usrname and passwd..the previous username and password will be lost..

In the next time when you run the application, first read settings from ini, and append in logins list
-

readsettiing(); or writesettings(); and how?regards

these are my working functions..now please help me out..how shall i first read settings from ini and append in logins list..
@void MainWindow::readSettings()
{QSettings settings; int size = settings.beginReadArray("logins"); for (int i = 0; i <size; ++i) { settings.setArrayIndex(i); login.userName = settings.value("userName").toString(); ui->lineEdit->setText(login.userName); login.password = settings.value("password").toString(); ui->lineEdit_2->setText(login.password); logins.append(login); } settings.endArray();
}
void MainWindow::saveSettings()
{
QSettings settings;login.userName=ui->lineEdit->text(); login.password=ui->lineEdit_2->text(); logins.append(login); settings.beginWriteArray("logins"); for (int i = 0; i < logins.size(); ++i) { settings.setArrayIndex(i); settings.setValue("userName", logins.at(i).userName); settings.setValue("password", logins.at(i).password); } settings.endArray();
}

hey i got it..

Hi cicncirin r u there,
Hey Whether we can get the date in an .ini file?regards
gogoi -
Yes, sure. You can write an "variant":http://doc.qt.nokia.com/latest/qvariant.html#QVariant-23
Then, you can read variant from ini and transform to "date time":http://doc.qt.nokia.com/latest/qvariant.html#toDateTime -
