1. Accessing Variables in your project
Scope
Accessing Variables in your project

2. Block Level
If you dimension your variable in a block of code such as if/then, for/next, or select/case, that variable disappears from memory when the block is done

3. Procedure Level
If you dimension your variable within a subroutine or function, that variable disappears from memory when the procedure is done

4. Module Level A module is a large block of code identified as a module.
Normally it is it’s own file—but not necessarily.
If you dimension your variable in a module, but outside of any subroutine or function, that variable disappears from memory when the module is done.
…Unless you dimension it Publicly: Public intMyVariable As Integer
Module level variables are good in all blocks and procedures of the Module

5. Procedure Scope
You create your subroutines as Public if you wish to share them between code modules
Or private if only that module can use it
Private Function myFunction()

6. Namespace Level
Relevant to large projects that may consist of several VB projects that interact.
