Hello, how can I expose events in a vb.net class to a vb6 client?

'Here is the vb.net code
<GuidAttribute("1b08d99b-cb12-420e-bb47-4ec73795bd9c")> _
<ClassInterface(ClassInterfaceType.AutoDual)> _
public Class DotNetClass
    Public Event GenericEvent(ByVal EventName As String)

    public sub new()
    end sub

    public sub test()
        RaiseEvent GenericEvent("test")
    end sub
end class

'Here is the vb6 code
private withevents oDotNet as DotNetClass

I get an error here saying that 'Object does not source automation events'

What am I missing here?
Thanks

Hi,

Mark the class and its methods as comvisible.
