Here is one for you. Suppose for some reason you need to use a reserved VB/.NET keyword or function name as a variable name. For isntance

Dim String As Integer

That will normally bring up a compile error. But lets say for some reason you need to use String as a variable name. How do you do it?
Use brackets

Dim [String] As Integer

and every time you need to access it, make sure you do so with the brackets

[String] = 50
