How to get file path?

[Mars Su]

Hello everyone,

Please take a look at the enclosed image. How could I get the file path value in case "True"?

(Case "True" description: there is no path input to "Read from Text file", a dialog box will pop up for selecting file. I want to get the path value and pass it back to the file path control on front panel. )

Thanks in advance

If you use the Close File function, the output is the path to the file.

You might consider using the function "Check if File or Folder Exists" instead. The path may not be empty, but that doesn't mean the file exists.

Use the file or folder exists? output to control your case statement and use the dup path for the read file function.

Thanks. "Check if File or Folder Exists" does avoide the VI to open unexist file, but it couldn't deal with empty path. So I combied both "Check if File or Folder Exists" and "Empty string or path".
