[rru]

I am using ViscualC for Communicating with instruments. One of the PC has Keithley GPIB card and i have pgms which works on this. I want to find out whether i can use somekind of patch which will help to use the same pgm on other machine which has NI gpib card

Hello,

There is no patch or a program that will convert the functions used in a 3rd party driver to be used with a NI board. The problem is that 488.2 don�t define the API for its functions so the way you call them will be different. If you are using VISA, then it would probably work just by replacing the VISA with the NI-VISA because VISA is a standard.
If you are using the 488.2 a work around would be to create yourself a wrapper for the functions that you are using to convert them into the NI-488.2 calls. Meaning that you will define in a different code that when you call the 3rd party operations to really be calling the NI functions.
I hope this helps.
