Reading from and writing to file in The Qt Resource System (qt 5.0.2)

Question

I have the code below. I am using Qt_5_0_2_MSVC2012_64bit-Release. I am not able to read the file. I get the debug error message of "Cannot open file for reading".There is some problem for me with resource files. Any idea how I can fix it? Thanks!

#include <QCoreApplication>
#include <QFile>
#include <QString>
#include <QDebug>
#include <QTextStream>
#include <QResource>
#include <QIODevice>


void Read(QString Filename){
    QFile mFile(Filename);

    if(!mFile.open(QFile::ReadOnly | QFile::Text)){
        qDebug() << "could not open file for read";
        return;
    }

        QTextStream in(&mFile);
        QString mText = in.readAll();

        qDebug() << mText;

        mFile.close();



}
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    Read(":/MyFiles/myfile.txt");
    return a.exec();
}

I had same problem. The Error string was "Unknown error".
Solution was to add INCLUDEPATH += . from @gatto's answer and run commands from menu:

1. Build -> Clean all
2. Build -> Run qmake
3. Build -> Rebuild All
