Its not clear what you are doing. Are you trying to create a sequenceCall step dynamically (at runtime) or in the editor.
If you are doing it in the SeqEditor, why dont you use the Specify Module dialog, after inserting the required data types in the sequence parameters tab window.
i am trying to create the sequence Call at runtime. That's why i need to set the parameters of the sequence that is supposed to be called . i am using TestStand 3.5
A good place to look, is at the code for the OI supplied with the teststand. You have a choice to look at, C C++ LabVIEW, C#....
Also the Programmer Reference Help from the Help menu item via the SeqEditor. Look at Writing an Application with the API, Starting an Interactive Execution.
please i don't understand you are meaning by OI. i searched in my Teststand files i i couldn't find any folder names OI. please tell me where i can find this examples, since i am working with c#, it would be very interresting for me.
Sorry about that, I mean the OperatorInterface folder, You should find a C## version.
