Save file path once and keep on using for next time

[Vindhyachal.Takniki]

1. want that when user first run the program, labview ask for file path. then save it as default path next time program run, unless user changes it to different file path.

2. Is there any example code by NI which i cna check?

I'm not sure that you can save stuff like this without writing it somewhere, but maybe i'm wrong and one of the more experienced guys will correct me.

That said, the way i have it set up is with a "Datalocation.ini" file, which is saved somewhere and shouldn't change. In this file is then saved a file path such as yours (or any number of other things).

+1 on what aero suggested-  there are examples on how to use the ini file vis too:

Configuration (INI) File.lvproj in the labview\examples\File IO\Configuration

Unnecessarily complicated and generally not worth doing is to save it to some registry setting.  Just thought I'd throw that out there, for whatever it's worth.

Check out the Configuration (INI) File-example

No need to go down the INI file rabbit hole when a simple one line text file containing the path will work.

@RTSLVU,

Thanks for replying. Can you attach the VI file of screenshot?

what block diagarm blocks it have?

Hi Vindhy,

RTSLVU attached a snippet - look for "snippets" in the LabVIEW help!

(And all those functions are found in the file functions palette…)
