Qt fails to create xml file: "No such file or directory"

Katia

I use code from tutorial and I get this error. I use Windows 10 and Qt Creator 4.7.1. I try to create Qt Widget application. Please help! I am stuck =(

QDomDocument document;
// Making the root element
QDomElement root = document.createElement("Dorms");

// Adding the root element to the docuemnt
document.appendChild(root);
QFile file;
file.setFileName("C:/logs.xml");
QFile("C:/logs.xml").setPermissions(QFileDevice::WriteOwner);
if (!file.open(QIODevice::WriteOnly | QIODevice::Text))
{
    qDebug() << "Failed to open";
    qDebug() << file.errorString();
}
else
{
    QTextStream stream(&file);
    stream << document.toString();
    file.close();
    qDebug() << "Done";
}

The "C" drive access is restricted on modern Windowses. Try another path.

Also, this line is completely unnecessary:

QFile("C:/logs.xml").setPermissions(QFileDevice::WriteOwner);

I found out that on Windows I need to use this kind of slash "\", so error is gone, it tells that file is created but directory is empty.

@Katia said in Qt fails to create xml file: "No such file or directory":

I found out that on Windows I need to use this kind of slash "\"

Speaking for Qt, that is wrong.

@sierdzio is right, check permissions.

@aha_1980 , I am sorry but how do I check permissions? I tried different directories and everywhere it failed. Also the guy who told me to use backslash told that he checked and it worked for him perfectly.

I added to program checking if file exists. Qt tells it does but directory is empty.

Hi,

What do you get if you try to open a file that actually exists on your hard drive ?
