Please note:

There is no 'below code' in your post.
There are tons of tutorials on serial port programming for VB.NET available.
You have to know the wighting bridge own protocol in order to process received info.
(In my opinion) Copying code from the web without properly understanding what you are doing is not the best of the approaches.
