Table Of Contents
File Dialog (G Dataflow)
Displays a dialog box with which a user can specify the path to a new or existing file or directory.
button label
Text to display on the OK or Current Directory button in the file dialog box.
If button label is longer than the width of the button, the file dialog box does not display the entire label. The button is typically about 11 characters wide.
Default: Empty string
prompt
Custom message that appears as the title of the file dialog box.
Default: Choose or Enter Path of File
start path
Path of the directory whose contents are initially displayed in the file dialog box.
If start path is valid, but does not refer to an existing directory, this node 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
default name
Name you want to appear as the initial file or directory name in the dialog box.
Default: Empty string
error in
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
pattern
A string containing special characters that this node uses to restrict the files displayed. pattern does not restrict the directories displayed.
Definitions of Special Characters
The pattern matching used by this node is similar to the matching used in matching wildcards. A wildcard is a keyboard character such as an asterisk (*) or a question mark (?) that you can use in place of one or more characters when you search for files. Use wildcards in place of one or more characters when you do not know what the real character is or you do not want to type the entire name.
Characters behave as described in the following table.
| Character | Meaning | Example |
|---|---|---|
| ? | Matches any single character. | If you enter multi?.doc, this node locates the file multi1.doc or multis.doc but not multiply.doc. |
| * | Matches any sequence of zero or more characters. | If you enter *.html;*.doc, this node locates all files with the extensions .doc or .html. |
| ; | Separates patterns, allowing you to specify multiple allowable patterns. Do not insert whitespace following this character because this node interprets whitespace literally. | If you enter multi.doc;multiply.doc this node locates both the file multi.doc and multiply.doc. |
| All other characters, including white space | Matches the exact character. | If you enter multi.doc, this node only locates the file multi.doc. |
Default: *.*
pattern label
Text to display in the file dialog box next to the custom pattern. If you do not wire a string to pattern, this node ignores this input.
Default: All Files
selected path
Absolute path to the file or directory selected using the file dialog box. If the user cancels the dialog box, this output returns <Not A Path>.
exists?
cancelled?
error out
Error information.
The node produces this output according to standard error behavior.

Where This Node Can Run:
Desktop OS: Windows
FPGA: All devices (only within an optimized FPGA VI)
Web Server: Not supported in VIs that run in a web application
