Hello Imemendes

Refer to the Write-Read Text File VI in the labview\examples\general\functions\File IO directory for an example of using the Write to Text File function

Sounds like you should go through some of the online tutorials.  Or you could use the LabVIEW Example Finder (Help->Find Examples) and do a search for Write File.

i'm grateful by your response

i achieved a solution to my problem but it seem is not enough

now i need to make three graphics but i'm stuck in a string

i read a file with three line, which every line gives me a different values, i want make three different graphics with that, but i need to separate the string, since lab view show me only one line

in the file is like this

0.0
24.1
40.2

in the lab view is like this

0.0 24.1 40.2

i would like if possible your help to separate this string

i upload mine vi to see how i was

sorry i could'nt save in lbv 11

this is my code 

my second objective is read the information in file values.txt, then make them appear in three graphics

in first attempt i try to take da string and convert to number by a array (not in the image) then transforming in a cluster e after in graphic but all have de same have the same value, seems it was made like in the image, but made by a more complicate way.

i use de vi that Nghtcrwlr send and i have two problems, first the values appear like integer and i couldn't make the graphics

i try to use the "edit scan string" but i obtained the error " Scan failed. The input string does not contain data in the expected format

using the %f%f%f the same error ocurred

[crossrulz]

Now that your format constant is using "\" display, get rid of the extra slashes.  It should read "%f\n%f\n%f"

you are not closing the the file in use, that is why you get the messege and your string format....

apok there are two differents files 

the first "setpoint.txt" that the only problem is the decimal values but i think the problem are the the difference between "." and ","

the second file is "values.txt" this file is in constant actualization and this the base to may graphics

crossrulz i try use this three and always have the same error

%f\n%f\n%f

%f\n%f\n%f

%f/n%f/n%f
