Driver to control Keithley 3706A with visual basic application using ethernet cable

I'm trying to develop Visual Basic code to connect my PC to a Keithley 3706A multimeter via an Ethernet, I have found this driver "3700/3700A Series IVI-COM/IVI-C Driver version 2.2.0 | Tektronix",and in the driver I have found a Visual Basic application as an example and use it to connect to the keithley.
Unfortunately, this code only works with the GPIB communication, and I can't find any other function in this driver that is used to connect to the Keithley via Ethernet.
I have attach to this the example screenshots (code & design) and the function used from the driver.
Can you please support me with the best driver or another function to connect to the Keithley via Ethernet as soon as possible? 

The IVI driver is probably the way to go.
The IVI driver "sits upon" NI VISA for the communication with instruments.
Instead of GPIB0:: type resource name, pass info for your LAN connected instrument.
Typically like this:  TCPIP0::192.168.1.50::inst0::INSTR
Substitute your IP address in there.

Attached is a form file from a VB sample using IVI driver and 3706A.

thank you for your support.
I have some question

• The cmdScan and the cmdSimple are two buttons?
• do you have any liste of the function to configure the Keithley, I mean like the one you use it to configure the Keithley to read the a DC volt and to declare the NPLC;
  • _driver.Measurement.Function = Ke37XXMeasurementFunctionEnum.Ke37XXMeasurementFunctionDCVolts
  • '_driver.Measurement.Nplc = 0.1
  • driver.Scan.AppendScanList("1002", "myTempCfg")
