I cant set the target for my xAP packet in VB.NET

["jimfranklin63" <jimfranklin63@xxxxxxxxxxx>]

Hi,
I am new to this xAP stuff, but I have got a simple vb6 app talking
to the X10 connector, and I can turn stuff on and off ok.

Ideally I'd like to write it all in VB.NET but i cant figure out the
syntax to set the target address.

here is a snippet of code, it sends packets ok (the xAP message
viewer sees them, but the X10 Connector knows they aren't for him,
and ignores them).

Dim Message As xAPMessage
Dim xsender As New xAPSender
Dim block As xAPMessageBlock

Message = New xAPMessage()
Message.Header = New xAPHeader()
Message.Header.Class.FullName = "xAP-X10.Request"

block = New xAPMessageBlock("xAP-X10.Request")
block.Add("command", "on")
block.Add("device", "A2")

Message.AddMessageBlock(block)

xsender.Connect()
xsender.Send(Message)
xsender.Close()

... End of Code Snippet ...

I tried adding the line

Message.Header.Target = "ERSP.X10.DEVPC"

But this gives an error. Can someone help me please?
