The ATML TD translator calls the UpdateActionParameters callback after translating <Parameters>, <TestResults>, or <SessionData> child elements of each <Action> or <Test> element.

Typical Use

Use the UpdateActionParameters callback to add, delete, modify, or reorder parameters passed from TestStand to the code modules. Only this callback can add, delete, modify, or reorder parameters.


The following figure shows the controls and indicators connected to the VI connector pane.


  • TranslatorCodeGenerator—Automation Refnum control that uses the TranslatorCodeGenerator interface.
  • CodeGenerator—Automation Refnum control that uses the LVCodeGenerator interface.
  • DOMNode—Automation Refnum control that uses the MSXML DOM Node of the <Action> element.
  • ParameterCollection—Automation Refnum control that uses the ParameterInfoCollection interface.
  • Error Out—The error out cluster, which contains the error status, code, and source information.
