QNetworkAccessManager contineous fetching data crashes app

spsp

hi,
I am developing app has to fetch data from sever continuously n print on screen , this app is running fine but after some time (aprox 30 min) shows memory full error and exits...

please someone help me resolve it ....

even i am setting don't save cache n even cookies...please help me...

my code to fetch data is as follows..

@
void mainWindow::Connection(QString url, QString data)
{
QNetworkRequest request=new QNetworkRequest(QUrl(URL));
request->setHeader(QNetworkRequest::ContentTypeHeader,"application/x-www-form-urlencoded");
QNetworkAccessManager net = new QNetworkAccessManager;
QNetworkAccessManager::connect(net, SIGNAL(finished(QNetworkReply)),
this ,SLOT(replyFinished(QNetworkReply)));
request->setAttribute(QNetworkRequest::CacheSaveControlAttribute,false);
request->setAttribute(QNetworkRequest::CookieSaveControlAttribute,false);

QByteArray data;
QUrl params1;

 net->post(*request,data);

}

void mainWindow::replyFinished(QNetworkReply *reply)
{
if(reply->error()==QNetworkReply::NoError)
{
QString data=reply->readAll();
qDebug()<<reply->url().toString();

}
else
{
    qDebug()<<reply->errorString();
    Error *msg=new Error("no Internet connection.");
     msg->show();
        }
reply->deleteLater();

}

// again call to connection fn after delay of 15 sec

}

How do you delete objects, for instance QNetworkReply?

spsp

i am using " reply->deleteLater(); "

Do you have to create a new QNAM for each request? Could you use one manager?

spsp

i have all diff request like i have 4 to 5 different Urls and even i am having some other requests except this timer request on particular button press ,so i implemented like this ... i don't know i can use or not...

What about such code, which will use one QNAM and connect to finished signal of reply.

@
void mainWindow::Connection(QString url, QString data1)
{
QNetworkRequest *request=new QNetworkRequest(QUrl(URL));
request->setHeader(QNetworkRequest::ContentTypeHeader,"application/x-www-form-urlencoded");
request->setAttribute(QNetworkRequest::CacheSaveControlAttribute,false);
request->setAttribute(QNetworkRequest::CookieSaveControlAttribute,false);
QByteArray data;
QNetworkReply * reply = manager->post(*request,data);

connect(reply, SIGNAL(finished()),
        this ,SLOT(replyFinished()));

}
@

By the way, you have two variables which the same name
@
QString data //in function parameters
QByteArray data //within body of function

i have just given sample ... i can't post complete code so...

ok i will try..
