How do you access the forms child objects from a different class?
-
I'm trying to access my forms (Form1) child objects, such as panels, sliderbars, toolbars, etc from a second class that i've added to the project. Currently i'm accessing Form1 via
Form1.ActiveFormthe problem that i'm having is that i can access the standard stuff from the form class, but nothing else, is this because Form1 is a public class, and all the child objects are private? if this is the case is it safe for me to change only the objects that i need to access to public, or is that unsafe coding? Is there a better way? or am i just going about this all wrong? :-D :laugh: ;p :^) :sigh: -

Your second class shouldn't know anything about the form that called it. Your Form should be passing the data it needs to to the class methods and processing any return data required. Your second class should not be trying to modify the form, or read from it, at all. RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome

You should not make any field in a class public. See this article on Why make fields in a class private, why not make them public?[^]

Yes. But it depends on what you are trying to do. What is the purpose of the second class? And what is the reason for the interaction?

thanks for the information guys... what im' trying to do is set the form state upon load then save on exit. but i have much more to set/save than just the form size, and i was just trying to do it from a different class i'm still learning... :-D :laugh: ;p :^) :sigh:
