How to use CWGPIB API

[jkuan77]

Hello,

I want to use CWGPIB component to control a GPIB device such as power supply or spectrum.

First thing is to search the what GPIB device is on the bus, but I don't know which given API can be used to scan the device by feeding back parameters such as the address.

Can anyone help me?

Thanks very much

Hey Jkuan, 

Could I have more information for your question ?

What program language will you use ? 

Your OS system ?? 

Are you trying to use Measurement studio GPIB for your project ?

Hi, Sean:

I'm using Delphi for programming under Windows 7 system.

After I installed NI-488.2 driver for my GPIB card, I import CWGPIB component from ActiveX into my Delphi.

There are a lots of functions provided with this component, and I want to write a Delphi program to control a GPIB device, but I just don't know what and how functions are to be used to control such a device.\

Thanks 

JK

Hey JK ,

I found some article about how Delphi application using 488.2 software ,

I also found this http://www.ni.com/support/cw/cwtechspec.htm

it seems Borland Delphi and C++ Builder do not support the ComponentWorks IVI ActiveX controls

because the controls were developed in Visual Basic (that is, Delphi and C++ Builder do not support ActiveX controls developed with Visual Basic).
