The ATML TD translator calls the PostTranslateStep callback after translating each <Step> element.

Typical Use

Use the PostTranslateStep callback to change properties other than post actions of the step and deallocate resources the PreTranslateStep callback allocated.


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

  • TranslatorCodeGenerator—Automation Refnum control that uses the TranslatorCodeGenerator interface.
  • Step—Automation Refnum control that uses the TestStand Step interface that <TestStand>\Bin\teapi.dll defines.
  • DOMNode—Automation Refnum control that uses the MSXML DOM Node of the <Step> element.
  • Error Out—The error out cluster, which contains the error status, code, and source information.
