Hello Mike,

From your description, you're using WSE 2.0 DimeAttachment to upload some
binary document in webservice. And you're wondering what's the proper value
should be pased to the constructor of DimeAttachment class, correct?

As for the DimeAttachment constructor, it mainly take some paramters to
determine the content type(mime type) and content (binary stream) of the
attachment. e.g.

=============
Dim dimeDocument As DimeAttachment = New DimeAttachment("text/xml",
TypeFormat.MediaType, New MemoryStream(Encoding.UTF8.GetBytes(docXml)))
=============

Therefore, for the first string based "type" parameter, you can just pass
the http mime type according to the document's type you want to upload. For
example, for jpeg image, it is "image/jpeg", for pdf file ,it is
"application/pdf", for rtf file ,it is "application/rtf". Also, if you
really not sure the exact content type of hte binary stream, you can simply
pass "application/octet-stream" for any unknown binary content. For second
TypeFormat enum parameter, you can simply use TypeFormat.MediaType.

BTW, DIME is a legacy binary transfering mechanism in WSE2.0 and in WSE
3.0, it has involved the new MTOM approach which is more recommended. If
possible, we would suggest you consider upgrade to use WSE 3.0 and MTOM.

Please feel free to post here if there is anything unclear.
