GPIB using C++

Hello,

I want to communicate with an old optical spectrum analyzer HP71450 using C++ in order to learn and make it work faster.

I have a LabView interface for it and I controll it using USB-GPIB cable.

I read some sample program I found on the internet and I understand I need ni4882.h , and maybe other header files that replace "decl-32.h".

could someone help me started with this project?

first, I'm using windows7 on 64 bit computer - is the above file still suitable? if so, where can I found it? it not in any directory under document\national instrument.

can someone direct me to simple read-write file using GPIB?

thanks
