Trouble with function declaration

bikonja (3)
Hey, so i'm making this currency converter app for a school project.
I have a class which downloads a html using QT, and saves it into a .txt file. it was all working good, but then i had to change my .txt hardcoded path into a relative one, and i ran into some wierd issue while trying to put that aditional functionality into the class.

You have declared that getExePath is part of std::string, I think you meant to have it in your downloader class?
