Re: COM with ASP

I'm going to go out on a limb and mention that you are more likely to get help if you post the portion of the code in question. Does us no good to offer suggestions if we don't know what you have or haven't tried.

Re: COM with ASP

This may not relate to your problem at all, but it smells familiar, so I thought I'd post.

I ran into this with a .NET web service, and the problem is that anything that uses COM must be run in a single threaded apartment model. Not sure about "classic" ASP, but in ASP.NET, there is no way to tell your main thread to use STA.

The work around is to launch a new thread with marked as STA. I'm pretty sure this was discussed, at least a little, on this forum, maybe search around and see what you can find.

It is entirely possible that supporting DLLs that are needed by your COM object exist on your development machine but not on your web server.
