dwritting a comment to a file is, of course possible, you have many way to do that. The best way depends on what kind of file you have. I've never used lvm files, but I but would be very surprised that you need to stop the program to write.
In your application, what event shall start the write of the comment ? Do you want to be able to write a comment at any time (I mean while the measurement is running or not) ?
Sort out these questions, and then draw an appropriated architecture. If you need further help, post your VI and explain clearly what you expect the it to do.

Best regards.

Hello,

I need to write  a comment in any time, during the measurement is running.

If it is possible I can write the measuremnet in a excel file insted lvm file. but I don't know how do it.

I must achieve a signal and filter it. then I calculate the integral of this signal and record it in a file.

but I must write a comment during acquisition because the signal change in the time according my manipulation and

I write them on file to have corresponding between comment and values.

This is my VI file I hope it is clear!

Another thing. I would to change file in which write when a write comment to have a diffrent file for each conditions.

Thank you very much
