The project to build your own myfanuc.dll for your devices was created with Visual Studio 2017. If you’re using Visual Studio 2013 it is sufficient to open myfanuc.sln, right click project device -> Properties -> Configuration Properties -> General and change Platform Toolset to Visual Studio 2013 - Windows XP (v120_xp).

In case you use a different compiler follow the steps below, tested with Visual Studio 2008 and 2010.


  • Start Visual Studio, click on File -> New -> Project
  • Select on the left side under Visual C++ (1) Win32 (2), Win32 Console Application (3)

Choose correct settings

FIG 1:    Choose correct settings
  • Name: Enter myfanuc (4) (all lowercase)
  • Check Create directory for solution (5)
  • Location: Adjust the directory if needed
  • Click [OK]
  • Click on Application Settings (left side)

Application settings (DLL)

FIG 2:    Set application type
  • Select Application type -> click DLL (6) (uncheck all other items like MFC)
  • Click [Finish]

In Solution Explorer:

  • Right click project name myfanuc (not Solution!) select Properties
  • In Properties select Configuration: All Configurations (7)
  • Character Set: Use Multi-Byte Character Set (8)

Use Multi Byte Character Set

FIG 3:    Use MBCS
  • Under C/C++ -> Warning Level -> Level2 (/W2) (recommended)
  • Check C/C++ -> Code Generation -> Runtime Library
    Debug: If Runtime Library is set to Multi-threaded Debug DLL (/MDd) change it to
    Multi-threaded Debug (/MTd)
    Release: If Runtime Library is set to Multi-threaded DLL (/MD) change it to
    Multi-threaded (/MT)
    If you do not change these settings your DLL will not work on other Windows versions!
