What you need to do is format the text appropriartely with the data and save the resulting string to file.

I'll illustrate with an example.

Be back soon,,

All you need to create that VI from scratch is shown in the screenshot.

thk u joe. actually it like this

the user will in insert the for example

SED=001, a=1,b=2,c=3,

and press ok to save it,

thn the user insert second data

SED=002, a=2, b=2, c=3,

i can save to text file for but the second data is overwriten the first data

how to make this second. third and so on... data inserted to different line.

Did you attach a True constant to the "Append Data" input to whichever Write File VI you are doing?

In Ray's example, all of the data is put together in one string (I assume he has a carriage return at the end of his format string) and written out in one shot at the end.  It will show up as different lines.  If yours is overwriting, then you must have structured your code differently.

do you hv any example which i can refer ?
