Looking for information on how to setup a web service that receives attachments through either DIME attachments or other protocols. It must be in .net C#. I'm not finding many articles on what I need. Any suggestions on links/books appreciated.

theres a decent demo and tutorial here.....

I'm assuming of course that when you say 'attachment' then you mean a custom object..

if not let me know, exactly what you are thinking of...

Regards

Well the project stands as this:

1. vendor sends xml file.
2. we parse xml file for information
3. transfer files(pictures and documents) based on that xml from the vendor to our server.
4. save

if I can figure a way to send and receive the files the rest will be easy.

A webservice is probably not the way to go here, for passing these files.

theres probably too many differing types and you will no doubt run into a serialisation issue somewhere with one or more of the types.

it probably should be said that the only way to pass something to a webservice is by serialising it into xml.

Right now we don't have anyway for this sort of transfer. It's a completely new project/idea.

According to Microsoft a protocol called DIME may help you accomplish this.
This is illustrated here :
http://msdn.microsoft.com/en-us/magazine/cc188797.aspx
with example code here http://msdn.microsoft.com/en-us/library/ms824597.aspx

Also, this article (http://msdn.microsoft.com/en-us/library/ms996462.aspx) shows the advantages and disadvantages of using various technologies for sending attachments.

Or you may use an open source SOAP library such as PocketSOAP found here
(http://www.pocketsoap.com/pocketsoap/)
with examples for PocketSOAP implementations found here :

I used this as a start point for anybody having trouble. Pretty straight forward.
