Is VISA COM supported by NI?

Yes.

If so, how it is?

By installing NI-VISA

please provide me with the brief details of VISA and VISA COM.

VISA is an API for instrument control. VISA can control GPIB, serial, USB, Ethernet, PXI, or VXI instruments by making the appropriate driver calls based on the type of interface. This is specified by a resource name, so you can easily switch from, say a GPIB interface to a serial interface by changing the resource name. VISA COM is, as far as I can tell, primarily used for VB6 programming.

Thanks for your kind response.

I have already installed NI-VISA 4.1. But i couldnt find anything related to COM implementation.

Can i have something more about VISA-COM also?

Thanks once again.

I still like to have detailed description about pros and cons (advantage and disadvantage) of using VISA and VISA-COM.

The technologies (both external too) that are needed to develop both VISA and VISA-COM?

How can I proceed with VISA driver, if I want to extend?

 Thanks for your support!!

Hi,

First, you have to look in the VISA COM component of the Agilent IO Libraries Suite at www.agilent.com.

For example, I am using VISA-COM and IVI-COM from NI TestStand and everything is ok.
