Sample Code

' create and initialize the SOAP envelope
set e = CreateObject("pocketSOAP.Envelope.2")
e.setMethod "doImage", "urn:AttachmentService"

' create the attachments object, and switch to MIME formatted attachments
set a = CreateObject("pocketSOAP.Attachments")
a.format = formatMime

' create the parameter that has the attachment attached to it
set n = e.parameters.create("gif", empty)

' create the attachment, and create a reference between the attachment and the parameter
n.href = a.Request.Create ("c:\picture.gif", tnfMediaType, "image/gif").Uri

' set the required SOAPAction, then give the transport object, to the attachments object
t.Soapaction = "urn:AttachmentService/doImage"
set a.Transport = t 

' now we call send/receive/parse through the attachments object, so that it can 
' inject/extract the attachments before sending them through the transport
a.Send "http://interop.xmlbus.com:7002/xmlbus/container/AttachmentApp/AttachmentAppService/AttachmentAppPort/", e.Serialize

' parse the results
e.parse a

' find the response attachment
