[AccessD] Class Rebuttal was: Basic Unbound Form ...

And where do you declare the object?

Let's say MyClass has an event.  Now I have three forms that need to see
that event.


Dim withevents MyClassObject as MyClass

That would go in the declarations, but how to you get all three forms to see
the same event? If each form had this in the Form Load event:

Set MyClassObject=New MyClass

Now each will see AN event when it is raised, but if form1 triggers the
event, it's going to get the event from it's instance of MyClass.  None of
the other forms will.  However, if MyClass was a global variable:

Public GlobalMyClass As MyClass

And the Load events had:

Set MyClassObject=GlobalMyClass

Now, when the event is triggered all three forms see the event.

Huh?  What are you declaring globally?  You raise an event from the
class and sink it in the other objects.  What does a global have to do
with that?

A class object with custom events.  If you want multiple objects to
'see'
that/those event(s), then you have to declare it globally.

Putting it as a property of a form and keeping that form open is just a
hackneyed way of creating a global variable. (And is pretty stupid,
because if that form isn't needed, it's a waste of resources to keep it
open for a class that could be kept open on it's own.)

I'd be interested in seeing this instance where an unprotected global
variable has to exist.
