Generate User Event (G Dataflow)

Last Modified: January 12, 2018

Broadcasts the user event you wire to this node and associated event data to each Event Structure registered to handle the event.

If the event is not registered, this node has no effect.

user event

User event refnum created by a Create User Event node.

datatype_icon

event data

The data associated with an event. The data type of the event data input must match the data type of the user event data type input on the Create User Event node. For example, if the data type of the user event data type input is a string, the data type of the event data input must also be a string.

datatype_icon

priority

Value that defines how this node enqueues the user event.

Name Description
high priority Enqueues the user event and associated event data into the event queue in front of any previously generated normal priority events.
normal priority Enqueues the user event and associated event data into the event queue behind any previously generated events.

Default: (0) high priority

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

user event out

The resulting user event reference.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: This product does not support FPGA devices

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