save file while vi running

[heang]

hello
i was trying to save the table continuously. i have created the file path with date n time.
with vi write file, i try to save the table. but what i desire to do is doing the save file continuously. It means that the vi continues running, while saving data every 20 rows(for example).
i know it is the problem of looping.
but i was trying to use 'open/create/replace file' vi and 'write file' vi to be in the while loop..but it appears wrong message.it cannot be done as it says replace existing file.
i do not know what solution to deal.

regards

Try wiring a False constant to the Advisory Dialog input of the Open/Create/Replace File function. This will eliminate the dialog but you also need to make sure that you have set the function input to open or create.
