Namespaces

Namespaces allows to separate the different imported programs, especially when they are long like libraries.

In a module, simply enter (without any module name):

  Namespace Packet1
    Class ExternalClass
      Public Name As String = "Default"
    End Class
  End Namespace

To import them after, use Imports.

For example from another module of the project ConsoleApplication1:

Imports ConsoleApplication1.Packet1
Module Module1
    Sub Main()
        Dim LocalName = New ExternalClass
        Console.WriteLine(LocalName.Name)
        Console.ReadLine()   ' Displays "Default"
    End Sub
End Module

By commenting the importation line, the following error appears: ExternalClass Type undefined.
