that this number's version increase automatically every time I wish to save . To make it, I must add oneline additional at the beginning the file Para_MachineFile.txt( See thefile

Hello hassanaly_nadine:

It seems that you are collecting all data from the file at the beginning of the vi and replacing all of them after pressing the button. What I did is collect the version number at the start, increment it, and save it again after pressing the button. (Please see attachment) Is this what you asked?

I hope this helps.

I thank you much for your assistance, it is really what I will want to carry out.
I still have a little question. Let us suppose that I will like to have an original file Para_MachineDefaut.txt, it is this file which will be opened at the beginning of the excecution from my VI.
Now, When I click on the button "Enregistrer", I will like to carry out the recording in another file (Para_Machine1.txt).What I must do in this moment?In other words, I will thus want that it don't ecrase the «Para_MachineDefaut.txt» file, but that the recording is done in another «Para_Machine1.txt» file with the number of version well on.
I thank you in advance!

Hello hassanaly_nadine:

Well, you can close the reference first, then open another reference containing "Para_Machine1.txt"
(Please see attachment)

Anyway, if you have any other questions, please don't hesitate to ask.
