Open another GUI from my current GUI with out needing a message box

Hey so I need to hard code a path to a folder containing the figure file for my other GUI so that i can open it from my main menu GUI. I've looked into uigetfile, uigetdir, and uiopen. I don't want a message box appearing each time. Also, does anyone know if my file path stays the same when i compile the package using matlab compiler into an executable.

C: -> folder -> main_GUI.m, main_GUI.fig, folder2(contains next GUI)
