>>Dim Message As MessageObjectClass() = New MessageObjectClass(5)
>>Message(0) = New MessageObjectClass

Viv,

I get an error on the first line with "Too many arguments to 'Public Sub New()'

I have expanded the sample code to see if that help explain what I am doing;

     Dim MyParentObject As New Webservice.ParentObjectClass = New Webservice.ParentObjectClass
     Dim MyBuiltMessage As WebService.MessageClass = New WebService.MessageClass

     MyBuiltMessage.Property1 = "Hello"
     MyBuiltMessage.Property2 = 1

     MyParentObject.message(0) = New WebService.MessageClass()    <-- Error occurs here.
     MyParentObject.message(0) = MyBuiltMessage
