start path

Path of the directory whose contents LabVIEW initially displays in the file dialog box.

If start path is valid, but does not refer to an existing directory, LabVIEW strips names from the end of the path until the path is a valid directory path or an empty path. If start path is invalid, the last directory viewed in a file dialog box initially appears in the dialog box.

Default: No value — Displays the last directory viewed in a file dialog box

error in

Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

Default: no error

datatype_icon

pattern

A string containing special characters that this node uses to restrict the files displayed in the dialog box. pattern does not restrict the directories displayed.

The pattern matching used by this node is similar to the matching used in matching wildcards in Windows and Linux filenames.

Character Meaning
? Matches any single character.
* Matches any sequence of zero or more characters.
; Separates patterns, allowing you to specify multiple allowable patterns. Do not insert whitespace following this character because this node interprets whitespace literally.
All other characters, including white space Matches the exact character.
