[Qt-interest] Error encountered while using void setStandardOutputProcess ( QProcess * destination )

[Usman Ajmal]

Sorry friends...for replying so late.

I used the following code and it worked.

void MainWindow::sendImage()
{
    QObject *parent;
    QString command1 = "dd if=/dev/mem";
    QString command2 = "netcat";
    QStringList arguments;
    arguments<<lineEdit_ipAddr->text()<<"9001";
    QProcess *process1 = new QProcess(parent);
    QProcess *process2 = new QProcess(parent);
    process1->setStandardOutputProcess(process2);
    process1->start(command1);
    process2->start(command2, arguments);
    QTextStream cout(stdout);
}

Thanks to Chandru for letting me know the use of QStringlist  for arguments.
Thanks to Thiago for identifying the small tiny space before the last
quotation mark in "netcat ". Thanks to all other who helped
