use a USB6001 DAQ in a visual basic application

Can you answer these questions for me …………..?

1. My goal is to make a DAQ based automated tester – I will stimulate a circuit and measure and evaluate the circuit’s response. I am new to the USB-6001 DAQ and fairly new to Visual Basic.
2. How do I get a USB-6001 DAQ to talk to/listen to a Visual Basic application? I am using Visual Studio 2017.  If there is a better Visual Basic version, please advise.
3. Where is there reference information to learn how to use a USB-6001 DAQ with a Visual Basic application?
4. Is there a WAIT command (a time delay and to free up CPU resources) for Visual Basic as there is for LabView? What is it’s name in Visual Basic?
