VB is not showing the data input in arduino

Hi, im new to this field that is why im asking if you could help me with the program im doing.
Here are my questiins.
How can i print or show the data im receiving at the arduino in visual basics?. Ive tried using differnt commands but vb displays nothing.
I've just started learning arduino & vb for a week ,so please bare with my dumbness.
Any help will do, reading materials etc. The guides in the site are for arduino and not for vb so Im having a hard time.
By the way my project is to count the On state of the LED output that is being controlled and show that count in the VB.
Thanks
