Finally (Visual Basic)
Introduces a statement block to be run before exiting a Try structure.
Each Try structure must include either a Finally block or at least one Catch block.
Control does not pass from a Try or Catch block to the corresponding Finally block in the following cases:
An End Statement is encountered within the Try or Catch block.
A StackOverflowException is thrown within the Try or Catch block.

The Finally keyword can be used in this context:
