how can i tell...

[Guest]

hey all,

being kinda new with .net, how can i tell if i'm writing logic in my ui
that's suppose to be in the lower levels (business, data layers)? i know
about the ui process app block however, it's not clicking yet.

Anyone have some simple advice out there so i can catch myself doing this?

thanks,
ari

I am not a strict adherent, but if you have logic in your form then yes it
needs to be in a different layer.


button_click
'no logic here

dim c as controller=new controller
c.handle buttonclick...

The idea behind business objects is to abstract your problem domain from your
user interface. Problem domain is a fancy word that is used to describe what
your application is really trying to do. The best way to avoid mixing your
form code and your business objects is to design you business objects first.
Define all business objects that will support all the requirements of your
problem domain before even writing one line of code in a form.
