Because it's a B2B interface, and the specification I'm working from specifies an XML schema that the input parameter and return value have to comply with. Since the remote client will be sending XML, and I'll have to return XML, and I use XML internally in the service, there's really not much point to converting the data from XML into some artificial object model, just to convert it back to XML.

Although I don't know the answer, I may have a tip to you: I learned that, for some more complicated cases, a managed C++ wrapper is the way to go. Interop coding that takes hours or days of coding in C# often takes only a few minutes in managed C++. Unless you have a strong reason to stay with "pure C#", I'd consider using managed C++. I see dead pixels Yes, even I am blogging now!

True, but I'm on a short timeline, which is the main reason I'm using 3rd-party tools in the first place. We had found a few 3rd-party solutions for doing what we actually need from ghostscript, but they all have their own problems. In some cases, they can't even render the PDF properly. That's the only reason I'm even looking at anything as low-level as Ghostscript.

I would think that a Regular Expression would be the best way to fix this - RegExp "When the only tool you have is a hammer, a sore thumb you will have."

Looks fine to me (in FireFox). If i remember right, this is an IE bug - just do like the rest of us, and throw a space in with each blank line while silently cursing Microsoft. You**'re one microscopic cog** in his catastrophic plan...

I had the SMTP service set up to relay for the loopback address. I wasn't using any objects or scripting languages to test with, I was just telnetting into the service (telnet localhost 25) and typing in the commands manually. There error I kept getting was "Unable to deliver the message because the destination address was misconfigured as a mail loop." So far I've had no luck deciphering what this error message actually means. :-/ I've since changed the configuration so that the server monitors only 1 IP address, and does not respond on the loopback. I'm technically running 3 SMTP services on this system. I have an SMTP proxy running on my main e-mail IP address, on port 25. I have my main mail server running on the same IP address, on a different port. All mail to this server comes through the proxy (AV checks, DNSBL, Bayesian filtering, etc.) The MSSMTP service watches a different IP address, and is not used in conjunction with any POP3 or other service. I have a custom program that picks up the incoming messages from the Drop folder and processes them. I'm using this SMTP service sort of as a message queuing system for distributed communications. The problem is, I have to be able to send messages back to the other application via SMTP. I can't set the proxy to relay, because it's not a real SMTP service, it just relays to the other mail server. The other mail server won't allow me to "watch" port 25 on the loopback and the other port on it's primary IP address. It watches the same port on all watched addresses. I'm just trying to avoid having to install a 4th SMTP-related service on the machine. I have access to a relay server, but I'm trying to avoid using it, as I want to have control over the retry intervals if initial delivery fails.

Thanks, James. The AppDomain is what I was looking for. Grim (aka Toby) MCDBA, MCSD, MCP+SB
