Some things all beginners should know / do that will help them have a good start with VB .Net:
Set the following Options:
'can be permanently set ' Tools / Options / Projects and Soluntions / VB Defaults Option Strict On Option Explicit On Option Infer Off Public Class Form1 End Class
Use &, not + for string concatenation. Strings should be studied in some detail as they are widely used.
Spend some time understanding Value and Reference Types.
Never use Application.DoEvents. Pay attention to the 'Caution'. When you reach a point where this seems like something you must use, ask.
The documentation is your friend.
