Except for few exceptions like eleven, twelve, they pretty much follow a pattern. You could try a lookup table or a dictionary.

Define the variables

Imports...
Private Class MyProgram

Dim Addr1, Addr2, City, State, Zip  As String
Dim X, Y AS ...
Private Sub MyProgram_Load...
.
'Some Code.
.
End Sub

Private Function Info() As... 'Functions Return A Value, Otherwise Use a Sub

Addr1 = Addr1.Text
.
.
.
End Function

In the body of the class, before defining any function, so they have a global scope. You can read or change their value on any placce of your code.

There are all kinds of events connected to the controls on your form. Check the attached image. On the left is a combobox where Button1 is selected. On the right is a dropped down combobox that shows a partial list of the events asocciated with button1. All of them can be used by you. BTW this is the development environment from VB.Net express 2010.

If you click the left one you will have a list of all the controls on the form, including the form, also a list of variables, they are objects. If you select one of them, then click on the right combobox, there you will see the events associated with it.

Events are something happening.
Raising an event is like clicking a button, or resizing a form or moving the mouse on top of a label, or changing a color or a font. These are events.
The way the program respond to them is controlled by the handlers. If you have a button click, you could have a subroutine that responds to it; the connection is made by the clause "Handles Button1.Click" or "Handles Me.SizeChanged", etc, so the program knows what to do when that button is clicked or that change had occurred. The subroutine could have arguments that provide some extra useful information, but the response to the event is what exists between the line:

Private Sub ...

and the line

End Sub

Let's say you have Form1(frmMain) and Form2(frmSettings). On Form1(frmMain) you have two integer variables:
XScale and YScale.
If you are on Form2(frmSettings) and have there two textboxes txtX and txtY and a button btnOK, you can access and change the values on frmMain like this:

    Private Sub btnOK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOK.Click
        frmMain.XScale = val(Trim(txtX.Text))
        frmMain.YScale = val(Trim(txtY.Text))
    End Sub
