Hi everybody ! I am a beginner in labWindows and I have met several problems I would like to structure my project in order to have: - a main file - a file that gathers all the callback functions - Callbacks.c - a file that handles the importation of configuration files - import.c - a file that handles the exportation of results and configurations - export.c - a file with functions that handles the display of parameters/values in the panels, those functions will be called by the Callback functions - Display.c In parallel, I have a file Panels.h that gathers all the parameters of my panels For now, I encountered a first problem: I managed to display parameters in my panels when the code line "SetCtrlVal(panel, PANEL_NAME, project)" is written in the file Callbacks.c. However, if I move this instruction in a function of the Display.c file (function called by an other function of the Callback.c file), the display does not work.. Can I control my panels with several functions from several files or only with CVI CallBacks functions ? Thank you in advance for your answers !

did you consider my earlier post: you also need to make sure that your variables are unique and known so in main.c panel (etc.) has to be defined global, and in your other files you have to define it as extern.
