Hello sushk,
What GPIB device are you going to use? Is this a PCI or USB device?

Also,
Is the GPIB communication the only thing that you are doing in this application? Do you have any other cards? There are certain back ground processes that need to be installed that you need the full installer for (meaning that if you just copy the dlls or libraries over, you will run into problems).

Its a GPIB PCI card from NI.The device to be controlled is HP 5385A frequency counter... I have to read Serial port as well as parallel port,I am using the in built component for RS232 in VB2008.......I can actually install NI488.2 on the systems, it might not be that big a problem i suppose, but u can still answer the questions as it might help others..
I am also facing a lot of problems in reading or writing to the gpib device...Just to start of i need to send the command "ID" to the device and it has to send back the device model number. I used the write method(simple NI readwrite example )and the device responds...But does the data sent back by the device just stay in buffer as long as i dont read it? what kind of approach is suitable...will asynchronous write do any good...? suggestions will help..ill work on it for couple of days more and get back here ....thanks
