strip a file path into just the root directory and open it

[rscott9399]

Hi team

I have a task before me and would like to do the following

I have a file path. However, the path has more information in it then needed. In other words, it is drilled down a bit further then i need it to be.

I need to some how strip the first bit of the path and take that information and feed it into the default space for an open file button.

Does anyone have an recommendations on how to complete this task?

Thanks

If I understand you correctly, there is a path like "C:\a\b\c" and you need the "\b\c" in order to use it as "D:\default\b\c", right?

Use this to check if one path is relative to another http://zone.ni.com/reference/en-XX/help/371361R-01/glang/compare_two_paths/

It returns the relative part which you can combine with your default path. I don't have access to LV right now, but this should be straightforward.

You can use the Path to Array and then slice out whichever parts of the path you need and concatenate back again.

I read it the opposite way, he has c:\a\b\c and just needs c:\a or c:\a\b. In those cases, you would use Strip Path.

Or Get Volume Info if you're only interested in the "C:\" part of it

You are right, that is the standard way to do it, if you know how many elements to remove. You can also utilize the Common Path returned by the compare function depending on what you need.

This is the way i did it.

Seems to work ok

Broke it down into an array and then concat it back together with just the pieces i wanted.

One caveat , when it strips it out, it looses the  ":" colon in C drive, so concat a constant with it.

Thanks for the suggestions. Been a few years since i have worked with LV and getting back into the swing

Is there a reason you're not using the actual "Strip Path" and "Build Path" functions? These allow you to manipulate the path, platform independent. No worries about slash direction and appending the root.
