>If you want to hide it completely then you must mark it private. In that case you would have to explicitly expose members to the outside world. ie. you end up with something like this:

Public Class Upload
>	Friend Sub New()
>	End Sub
>	Friend Property SomeProperty() As String
>		Get
>			Return m_SomeProperty
>		End Get
>		Set
>			m_SomeProperty = Value
>		End Set
>	End Property
>	Private m_SomeProperty As String
>
>	Friend Function DoSomething(s As String) As String
>	End Function
>End Class
>
>Public Class PublicClass
>	Private oUpload As New Upload()
>
>	Public Property SomeProperty() As String
>		Get
>			Return oUpload.SomeProperty
>		End Get
>		Set
>			oUpload.SomeProperty = value
>		End Set
>	End Property
>
>	Public Function DoSomething(s As String) As String
>		Return oUpload.DoSomething(s)
>	End Function
>End Class

Ah, the famous Get/Set approach, thanks for the info
