Well first of all, great thanks kevin for trying to help.
I didnt really understood what should i do..
your idea sound very well, but one problem, buttons are boolean (by the way i could not find the "boolean array" over labview, so please, if you can to write where it is

) and as they are boolean, they're value will equal, so it will not be able to recognize which button pressed, plz correct me if i made a mistake..
i need a thing that some-how know to work like if\else in C's different languages.
something that work like this
"button 1 has been press so ill enter case 5. now button 3 and 7 pressed together, this would enter to case 4"
ill hope my little example will help you to help me better
Great thanks for you kevin and for every one that can help me to solve my desire lol
