path stand alone

[Identcor]

Hi,

I created a installation for my stand alone app. I´m worried about the paths of the files I' ll write with it at the new PC installation. Thinking about it I tried to "know" what the path of the vi or app running to save the files at the same directory. I used the "Current Vi's path" and tried to concatenate with the name of my file but it didn't work. Please see the attached vi. If anyone could help me I'd thank. I'm accepting sugestions too.

Thanks,

Celia

Hi Altenbach,

I´ve already seen the link you send me. Have you seen my vi in attchment? I couldn't concatenate the path with the "Concatenate String" yet. It don´t work. Try it and tell me.

Thanks,

Celia

If your VI is at c:abc\myvi.vi, then that's what the current path returns. You are trying to create a file c:abc\myvi.vidata.txt, probably not a good choice!

NEVER use path-to-string or string-to-path unless you are dealing with an OS specific function. To manipulate paths, you should use exclusively strip path and build path functions. In this case, you would strip once when in the development environment and twice when in an executable. There is an openG function that automatically does it or you can write your own.

Hi Altenbach,

Thank you for your attention. I tried your suggestion but the result was the same, it didn't concatanated the name of my file data.txt, that is: My directory is c:\1747 and I want c:\1747\data.txt to use in file path terminal of the New File, but the result in appended path terminal of the Build Path is only c:\1747\

Thanks,

Most likely, your indicator is not wide enough! 🙂

A path indicator will wrap to a new line at path delimiter boundaries. Just resize your indicator to see it all.

Could this possibly be an issue with "current vi's path" changing when deployed as an exe? 

E.g. in development current vi's path = c:\path\my.vi but as a deployed exe = c:\path\myapp.exe\my.vi

To get the right home dir your must use two calls to "strip path"
