Hi

How should I define a variable in a class so that the variable is visible to
any code that is using the class?

Thanks

Regards
 
Public Variable As Type

or

Public Shared Variable As Type

The difference is the first is an instance member, which is valid for each
instance of the class. The second is a static member, and so does not
require an instance of the class and will not be different for each
instance.

You may want to create a public property for the class which would allow you
to validate the data that is being passed to the property.

Should it read "that is using the class" or "that is using an instance of
the class"?

\\\
Public Class Foo
Private Shared m_Bar As String
Private m_Goo As String

Public Shared Property Bar() As String
Get
Return m_Bar
End Get
Set(ByVal Value As String)
m_Bar = Value
End Set
End Property

Public Property Goo() As String
Get
Return m_Goo
End Get
Set(ByVal Value As String
m_Goo = Value
End Set
End Property
End Class
///

The property 'Bar' can be accessed without creating an instance of the class
'Foo', 'Goo' requires an instance of the class.

Hi Tom,

|| Foo, Bar, Baz, Moo, Goo

Isn't that a delicious Thai meal?



My sequence is Foo Bar The Elephant.

If it has to go further it's then Foo Bar The Elephant Went To Town ...

A wierd mixture of Babar the Elephant and a land-based Owl and Pussycat
;-)

Have you seen Okeydoke, the Moomins or Pingu recently. I've just bought a
Pingu DVD (for my younger brother).

That's nice - plenty Pingu.

|| (for my younger brother).

Yeah, like I believe <that>. It's ok, you can tell us, you're among
friends. ;-)

The only Okeydoke I know is "Okey-diddly-dokey" - to quote Ned Flanders.

Fergus
