Syntax

Engine.CallFrontEndCallbackEx ( sequenceNameParam, argumentList, handlerType = ConflictHandler_Error, reservedParam = 0)

Return Value

Execution

The Execution object of the newly created execution.

Purpose

Calls the Front-End callback sequence the sequenceNameParam parameter specifies.

Remarks

Front-End callbacks, which are callbacks the TestStand Sequence Editor or a TestStand User Interface call, allow you to customize the sequence editors and user interfaces on the system. Each sequence editor or user interface chooses which Front-End callbacks it calls. The FrontEndCallbacks.seq file in the <TestStand>\Components\Callbacks\FrontEnd directory contains the Front-End callbacks National Instruments defines. Currently, National Instruments defines only the LoginLogout Front-End callback. You can override the National Instruments version of LoginLogout or add custom Front-End callbacks in the FrontEndCallbacks.seq file, which is located in the <TestStand Public>\Components\Callbacks\FrontEnd directory.
