I'have just see, that i forgot to post the vi sorry TextFile 8720091.vi

You have many lines in your text files, cause when you push the button, it will stay in true, and you don't put a sleep. I correct your vi in LV 8.5. I put a delay in your while loop, and change the "commut action" (??, i don't know the word in english, sorry) of your boolean. It will put himself at "false" after you push the button. Sorry, i'm not very good in english.

Hi lab, You have many blank lines, because you write on your file at each iteration. You just have to write your data when you acquiere your data, not all time. The solution is to put the "write in file" sub-vi in your case structure TextFile 3720091.vi
