Hi rodmjay,

    Use the singleton pattern...

Public Class SingleInstance
    Shared myInstance As SingleInstance

    Private Sub New()

    End Sub

    Public Shared Function returnSingleInstance() As SingleInstance
        If myInstance Is Nothing Then
            myInstance = New SingleInstance
        End If
        Return myInstance
    End Function
End Class
