Sets variables to be visible in an ESP scripting template. You can access these variables from the form variables in the ESP template. Refer to the Scripting in LabVIEW Web Services topic at ni.com for more information about using scripting with Web services. The data type you wire to the value input determines the polymorphic instance to use.

Inputs/Outputs

  • cNI__WebServices_lvlib_Web_Requestlvclass.png LabVIEW Web Service Request —

    LabVIEW Web Service Request is an identifier used by Web Services VIs to reference a specific HTTP request. LabVIEW Web Service Request works similarly to a refnum in LabVIEW, allowing you to wire together Web Services VIs within your application. You must wire Web Services VIs to the LabVIEW Web Service Request control or an existing value from the LabVIEW Web Service Request out terminal of another VI.

    When you use Web Services VI(s) within a Web method VI, you must assign the original LabVIEW Web Service Request control to the connector pane of the Web method VI.
