Thank you!
just now i built a dll. at the beginnig i didn't set the export VI,
prompt: Labview: An input parameter is invalid
Application Bulider: you must export at least on VI
when i set a export vi,it worked.
i am not sure the input and output parameters of this dll,and how to set the export VI.
For example,the add vi. how can i build a dll?
should i set the controls for adden and augend,the indicate for the result? Which VI should be
the export vi.
