Passes the arguments you include when launching an executable built in LabVIEW NXG from the command line to the VI.

connector_pane_image
datatype_icon

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.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

application name

The name of the executable you specify from the command line.

If an error occurs, application name returns as an empty string.

datatype_icon

arguments

The arguments you enter when launching the executable from the command line.

An argument that contains double quotation marks (") will return as a value without the quotation marks.

If an error occurs, arguments returns as an empty string array.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Running Applications from the Panel

Get Command Line Arguments only retrieves the arguments passed when launching an executable built in LabVIEW NXG from the command line. This node returns empty outputs if you run it from the panel.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
