I wrote an abstract base class from which I've derived a few other
classes. I'd like to create a base class array where each element is
an instance of a derived object. I can create a base class pointer
which points to an instance of a derived class, but when I pass that
base class pointer into a function, it can't access the derived
object's public functions. Although, the base class pointer does call
the appropriate virtual function...

Widespread opinion is that public data members are evil, because if you
have to change the way the data is stored in your class you have to

Hi,
I am having some problem, I declare few variable in a public module and use

Thanks,

I'm still trying to sort out in my head the differences between public and
shared when referring to declaring properties or variables. This is my
understanding:
shared - akin to a 'global' variable for the application. Any other code
within the application can access it.
public - can be shared across the application if instatiated.
Does that sound about right? It seems these are more useful for methods
rather than variables. Most of...

I am seeing on my local development box that once the variable is created
and loaded with data and stored into the session variable that on the next
aspx page, before the first line of the page load is executed, the public
variables data persists. I have not done an assignment from the...

If I have a class with a public variable, isn't this the same as a
private variable with a property? ie, isn't this:
Public Class MyTest
Public MyVar as String
End Class
the same as this:
Public Class MyTest

OK, I've searched all over and used the help on the VBA editor. Helped a little but I'm not getting close enough to see where I'm going wrong.
I need a public variable that I will be able to use on different forms as part of the join property in a SQL statement. I think it would easier to make it a public so I don't have to create the variable in every button it might be used in. Here is what I've come up with so far. While I get no errors...
