How to search file name and making into the TXT file

[RiceBall]

I want to search specify file name and make the name to the bat file.
Now I can make a file name is auto.bat.
And make the first sentence AUTOLOAD.BAT
Following is my code.

QFile file("auto.bat");                                    //建立或開啟auto.bat檔案
    file.open(QIODevice::WriteOnly);                           //開啟檔案
    const char *data = "AUTOLOAD.BAT";                         //建立第一個字串AUTOLOAD.BAT
    file.write(data);
    file.close();

Now I want to search specify file name (.B) and make sentence under the first.

  QStringList QfilterB("*.B*");                              //指定要篩選的字串
   foreach(QFileInfo Bitm, mDir.entryInfoList(QfilterB))
   {
        file.write(Bitm.fileName().toStdString);
   }

It shown alarm like this. How could I fix it ??

"QString::toStdString" is a reference to a function, "QString::toStdString()" is a function call.
But you're looking for QString::toUtf8()
