File Reading (Seems Weird To Me)

[Furkan]

Hello.
I know how to read files but I discovered something weird the code below works fine.

QFile file(QApplication::applicationDirPath() + "/bilgi.txt");
    if(!QFile::exists(QApplication::applicationDirPath() + "/bilgi.txt"))
    {
        QMessageBox::information(this, "asdasd", "not exists");
    }
    if(!file.open(QFile::ReadOnly))
    {
        QMessageBox::information(this, "asdasd", "readonly");
    }
    QByteArray data = file.readAll();
    QTextCodec *codec = QTextCodec::codecForHtml(data);
    QString string = codec->toUnicode(data);
    QMessageBox::information(this, "asdasd", string);

QFile file(QApplication::applicationDirPath() + "/bilgi.txt");
    if(!QFile::exists(QApplication::applicationDirPath() + "/bilgi.txt"))
    {
        QMessageBox::information(this, "asdasd", "not exists");
    }
    if(!file.open(QFile::ReadOnly))
    {
        QMessageBox::information(this, "asdasd", "readonly");
    }
    QByteArray data = file.readAll();
    QTextCodec *codec = QTextCodec::codecForHtml(data);
    QString string = codec->toUnicode(data);
    QMessageBox::information(this, "asdasd", string);

To copy to clipboard, switch view to plain text mode 

But when I remove these codes below

if(!QFile::exists(QApplication::applicationDirPath() + "/bilgi.txt"))
    {
        QMessageBox::information(this, "asdasd", "not exists");
    }
    if(!file.open(QFile::ReadOnly))
    {
        QMessageBox::information(this, "asdasd", "readonly");
    }

if(!QFile::exists(QApplication::applicationDirPath() + "/bilgi.txt"))
    {
        QMessageBox::information(this, "asdasd", "not exists");
    }
    if(!file.open(QFile::ReadOnly))
    {
        QMessageBox::information(this, "asdasd", "readonly");
    }

I can't read bilgi.txt file. I really wonder why it is like that.
Is there a really cool reason for that? or I don't know you tell me.

Weird, I replied once and it poofed. I hope I'm not double-posting lol.

Anyway, you removed the code that was opening the file.

Oh my God!
I can't believe I overlooked it!
Thank you so much!
