<DIV><FONT face=Arial size=2>Do your forms inherit from some master, or do you
have to implant this logic? I.e. can we create form classes and inherit from
them? And with them, their constituent control logic/instances?</FONT></DIV>

<DIV><FONT face=Arial size=2>Obviously I haven't investigated this stuff much
or I would know the answer :-)</FONT></DIV>

<DIV><SPAN class=025175323-03022003><FONT face=Arial color=#0000ff size=2>A
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>

<DIV><SPAN class=025175323-03022003><FONT face=Arial color=#0000ff size=2>A
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>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>
