Test chemin valide

[GerdW]

Hi Diane,

Yes checking empty values before concatenation could be a solution but I had to do it for each variable and each time I

concanate so for me I duplicate code... As I often call my sub VI I prefer to do the test inside, once.

What's the problem to include the concatenation part also in a subVI - with proper input checking added?

But when I convert string data to filepath I loose the "\\" and automatically just have "\"... Some options in the filepath command are activated?

There's no special command - here basic rules for creating file paths are applied!

(Atleast on Windows) there are no double backslashes allowed in filepaths - so they are replaced by a single backslash.

Again:

- building a filepath using an empty string is just a FAIL.

- Using simple string functions to build file paths also is a fail as you are advised (several times) to use the fiule path functions available in LabVIEW!

- check for empty strings BEFORE conversion to a file path - anything else will give you trouble!
