Ressource File Url not opened by QFile

[Chrysmac 0]

Hello Everyone,

I have attached herewith a simple project using a simple resource file that cannot be opened by QFile. I have just built the latest version of QT5.11 from source using Git and Qt Creator 4.7.82 from source (latest git version check out). For both, I used the same Visual Studio Enterprise 2017 version 15.7.2.

Can anyone please tell me what could be wrong?

Thanks in Advance.

I dont understand you cleary. You have a TestQFile.rar in your Resource and you just want to access it with the Url in a QFile? The Problem is maybe that everything in the Resource File, that is compiled into your Executable, is ReadOnly.

Hi,

What error do you get ?

What code are you using ?

By the way, upload of compressed archived are not enabled.

Hello and thanks for the answers.
I have a simple .txt file and I try to access it with QFile::open(). The following if always fails, no matter which projects[0_1527616248419_textfinder.cpp](Uploading 100%) :

QFile inputFile("qrc:/Resources/input.txt");
    if (!inputFile.open(QIODevice::ReadOnly)){
        qDebug() << "could not open " << inputFile.fileName() <<"\n";
        if (QFile::exists("qrc:/Resources/input.txt")){
            qDebug() << "could not find existing file " << inputFile.fileName() <<"\n";
        }
        return;
    }

The console gives me:

Starting E:\Qt\Tutorials\QtCreator\build-TextFinder-x64-Debug\debug\TextFinder...
could not open  "qrc:/Resources/input.txt" 

E:/Qt/Tutorials/QtCreator/build-TextFinder-x64-Debug/debug/TextFinder exited with code 0

You should use :/ to access your resources like shown here.

Can you post your .qrc file content ?

Sorry for my absence. I have tried almost every combination of /,//,///,\ and so on.
My Qrc file content is

<RCC>
    <qresource prefix="/" lang="C++">
        <file>Resources/input.txt</file>
    </qresource>
</RCC>

Hi
And you are using the plugin and are sure the files are actually compiled into the code ?
http://doc.qt.io/archives/vs-addin/vs-addin-managing-resources.html

I would do something like

QDirIterator it(":", QDirIterator::Subdirectories);
while (it.hasNext()) {
    qDebug() << it.next();
}

to see what you got.
