I am using wddx in VisualBasic to send/receive content

Private Function On_Q_Go_creatingWDDXMessage(ByVal component As Object,
ByVal strQ_Go_id As String, ByVal strPublish As String)
Dim objWDDXPackage As WDDXStruct
My code is hanging now here:
----> Set objWDDXPackage = New WDDXStruct

It can not create the objWDDXPackage. I googled for information how to
debug this object and how to get errors but without success.

any ideas appreciated
