how to using self-coded Vi file to drive and control a hardware or a card.

[ZhenCo]

Hi everyone.

Thank you for your time. Now I have coded a new vi file based on original vi file of a card or broad (name P7888) with some new function. My question is how to connect my new VI file to the card or broad and drive, control it. Do I need creat a new interface to fulfill this program? How to do that. Thank you very much. I look forward to hearing from you.

I assume there is a DLL you are supposed to call.  How did the original code access the hardware?

Thank you. Actually, the new coded Vi file include the DLL library. So I think the new Vi file already called the library. Is that right?

If you didn't add it, then it was already there.  That DLL is what is accessing the hardware.

So what you mean is that now my new Vi file should able to drive the card, is that right? But it dosen't work. In manual, it says that" Please do not expect any functions in this DLL for controlling the hardware directly" and "The Dll is an interface providing functions to communicate with the server program". So I need to let the new Vi file be able to control server program, is that right? How to do so? Thanks a lot again.

At this point, I recommend you contact the manufacturer.  They will be able to answer your questions.
