That should be

public property waarde1() as string
get
return msWaarde
end get
set
msWaarde = value
end set
end property

<cut>
The syntax is:

Public Property Waarde1() As String
Get
Waarde1 = msWaarde
End Get
Set
msWaarde = Value ' "Value" is implicitly defined
End Set
End Property

Cast it to the proper type:

ob = CType(list.Item(i), WindowsApplication2.clsTest)

It's a predefined variable that is present within the Set. Kinda like
Inserted/Deleted in SQL Server triggers.
