Hmmm - if things are working as they should, you should have an actual "GeneratedFiles" directory on disk at the same level as your source code. For my projects, the directory structure is typically:

Qt Code: 
  1. Solution root /
  2.     Project root /
  3.         Source *.cpp, *.h
  4.         Debug /      (for Win32 builds)
  5.         GeneratedFiles /
  6.             Debug /
  7.                  moc_*.cpp
  8.             Release /
  9.                  moc_*.cpp
  10.             qrc_<projectname>.cpp
  11.             ui_*.cpp
  12.         Release /  (Win32 builds)
  13.         Resources /
  14.            *.png
  15.          x64 /
  16.            Debug /
  17.            Release /
To copy to clipboard, switch view to plain text mode 

The qrc_<projectname>.cpp file is generated by RCC and is the conversion of your resources into binary strings to be compiled into your project.

Maybe you need to reinstall the Qt VS Add-in?
