Vatsal,

Attached is the DLL so you can try to use it in Visual Basic 6.

I hope this helps.

thanks gagi1...
but i still have one small problem...how to work with this .dll file in vb....how can i use this file to read the network analyzer

Although your driver is a Plug and Play driver and not an IVI driver, you can still refer to the following DevZone document:

I hope this helps.

Hi Vatsal,

The hp8720C.doc is the only documentation we have and is already included with the driver. This document is generated from the .FP file.

Hi Vesna,

I am sorry... I might be getting on your nerves but I uploaded the dll that you posted in an earlier reply... and i think there is no hp8720c.doc ... and if there is how can i generate it through .fp
Again sorry...but I need this one for my project.

Thank You
Vatsal

Hi Vesna,

I am calling the function after initializing the hp8720c network analyzer, but vb hangs up.

For i = 1 To 10

errcode = hp8720c.hp8720c_data_trans_to_array(instrumentID, dataType, realStimulus(i), imaginaryResponse(i))

Text1.Text = Errmsg(errcode)

Print "RealStimuls" & realStimulus(i); " imaginaryResponse" & imaginaryResponse(i)

Next i
