module is simply a container for code, nothing more. A module can contain
global variables, local variables, functions, subs etc. In the end
however, it is just a container full of code.</FONT></SPAN></DIV>

class module defines a class, and holds code and variables that implement the
methods and properties of that class. A class is a template for an object
and an instance of that object (class) will be loaded when you set a variable =
to that class. in other words.</FONT></SPAN></DIV>

<DIV><SPAN class=025175323-03022003><FONT face=Arial color=#0000ff size=2>You
use classes to create an object which will load into memory and do
something. </FONT></SPAN></DIV>

<DIV><SPAN class=025175323-03022003><FONT face=Arial color=#0000ff size=2>In my
framework I have classes for each type of control that Access provides.
One of my classes is for text boxes. Whenever a text box is opened on my
forms, I load a class and pass a pointer to the text box that just opened.
The text box class can now implement behaviors for that specific text box that
"belongs to it" (or v.v.). For example whenever the text box gets the
focus, I can cause the background to change colors. Or I could compute a
value based on the value it already contains * the value of some other
control. </FONT></SPAN></DIV>

<DIV><SPAN class=025175323-03022003><FONT face=Arial color=#0000ff size=2>So a
class contains the code for an object. When you dimension a variable of
type (whatever your class name is) and then set the variable, you load an
instance of the class. You can have just one, or a hundred instances of
your class. When my forms load, I have an instance of my text box class
for every text box on my forms. </FONT></SPAN></DIV>
