Displaying values coming from an Arduino on an interface using VB

Good morning!
I'm trying to display some values coming from my arduino board in real time. I have just one question please, so that I can complete it myself without bothering you. Which commands in VB .NET should I use to catch these values and display it in a textbox with ReadOnly=true ?
Thank You
