Set Headers (G Dataflow)

Last Modified: August 28, 2017

Sets a list of auxiliary headers that you want to send with the email. This node overwrites any existing header values before it executes.

reference in

The SMTP client reference for the current session of SMTP requests. You can create an SMTP client reference using Open Handle.

headers

List of auxiliary headers, such as Reply-to, Precedence, and References, that you want to send with the email. Standard headers such as To, From, Subject, CC, and BCC, are not transmitted even if you include them in the list, because the SMTP client automatically sets them. Each cluster in the list specifies the following elements:

datatype_icon

Name

Field name of the header that appears to the left of the colon.

datatype_icon

Value

Field value(s) that appear to the right of the colon.

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

reference out

The SMTP client reference for the current session of SMTP requests. You can wire this output to the reference or reference in input of other SMTP Email nodes. Use Close Handle to dispose of the reference and free system resources when you are done with the current session.

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: DAQExpress does not support FPGA devices

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