String to file path

[Cory_K]

I am looking for a function in LabVIEW and it seems to be hiding from me.

I have data write to a file in my VI.

There are 3 strings:

1) constant - file path preceding the name of the file

2) control - the user can type in whatever name they want

3) constant - ".txt"

The 3 strings are then concatenated.
Can I turn that concatenated string into a filepath?

It would be really cool if there was a "string to filepath" function, but I cant find it.

OK, nevermind

Of course right after I post my question, I found the function moments later.

Thanks anyway

Glad you found your own solution.  There are many ways of implementing your solution.  However, here are a couple of simple and straight-forward solutions that may be useful for someone reading this thread.

Actually, only the lower version is acceptable here.

The upper version will fail if the path is anything but "c:\" (or similar), because you'll not get the "\" delimiter. (e.g. if path is "c:\dir1", you'll end up with c:\dir1filename.txt instead of  c:\dir1\filename.txt. It is also hard to justify the use of three operations for something that can be done in a single step.

Also, remember that "string to path" and "path to string" can often break platform independence.

Hi-

This thread is still relevant 5 years later...

So, if I do want to have my base path as C:\dir1\ instaed of C:\ what shall I do?

Thanks

EDIT:  Just noticed I used base1 instead of dir1, but you should get the point.

Crossrulz-

Your suggestion to specify a subdirectory "base1" in the base path argument as: C:\base1 does not work. See the 2008 entry by altenbach. When doing that, the intended base1 subdirectory ends up being the prefix of the filename.

So, instead of obtaining: "C:\base1\filename.txt", I end up with: "C:\base1filename.txt".

[DaniDin]

The goal can be accomplished by simply concatenating the sub folder "base1\" as a constant before the filename.

So the base path is still "C:\", then in the second argument of the "Build Path" function, concatenate "Base1\ with "Filename", and with ".txt"

Did you run the crossrulz post?  It works as expected returning c:\base1\filename.txt  The comment altenbach said was that you may run into issues if you just use concatenate string instead of build path.

You are making life too difficult.  Trust me.  The code I gave you will do exactly what you want.
