I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I've not tried creating a C# DLL through Server.CreateObject (as I tend to use ASP.NET for interacting with .NET DLL's), so this is just an idea off the top of my head.

But from what I recall - Server.CreateObject is used for instantiating COM objects and thus is trying to create a COM object. A C# DLL is not a COM object and certainly wouldn't have a registered ProgID. This would fit in with the error message you are seeing.

No problem.  I rarely give anything but an "A".  I wish they would do away with "A" "B" "C" grades.
