GPIB (Visual Basic) question.

[Paul F. Prew]

I am writing a program in Visual Basic (ver6.0) (with several GPIB instruments,
but nothing fancy) and have at least 3 ways to conduct the GPIB communications.
1) Traditional calls to Gpib-32.dll 2) Multi-device calls to Gpib-32.dll 3)
ActiveX GPIB control provided by component works.
The ActiveX control seems very friendly, but, I'm wondering what the difference
in overhead (or other caveats) might be.
Although this centers around Visual Basic, since it concerns NI488-2, I thought
it prudent to post this question to this group.

I don't know the answer to your question, I just wanted to direct to the Developer Exchange forums on NI's site where you may get better responses. The "Measurement Studio For Visual Basic" or "GPIB" forums I would think would help you out.
