Hoger-Lager

Ik heb bijna een examen VB.net dus ben wat simpele applicaties aan't maken...

Deze applicatie is een klein spelletje, namelijk hoger-lager. De speler krijgt een (random) getal te zien, en moet zeggen of het volgende getal hoger of lager gaat zijn...

2 functies: higher, lower (retourneren true/false als ze respectievelijk correct of incorrect zijn)

Het getal dat weergegeven moet worden in het formulier zit in de property number.
Om een nieuw spel te starten (om de numbers goed te zetten dus, bij je onload) roep je de procedure newgame aan.

Voorbeeld van gebruik (met een knop hoger en een knop lager; daarbij 3 labels voor de scores en 1 label voor het getal):

    Private Sub btnHigher_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnHigher.Click
        If (hogerlager.higher()) Then
