[AccessD] Standard vs. Class Module

MessageDo 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?

Obviously I haven't investigated this stuff much or I would know the answer :-)

  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.

  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.

  dim lMyClass as MyClass
     set lMyClass = new MyClass

  You use classes to create an object which will load into memory and do something.  

  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.  

  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.

    Can anyone describe how to determine when to use a standard module and when to use a class module in Access?

    TIA    Myke
