>Well, that's what led me down this path. Thinking that if the DLL was local, and the message box didn't have an owner window, I might be able to workaround the inability to have any interface issue. It isn't that I needed one, it was just my curiousity that got me started. Jim's response indicates that it won't appear and that the application will hang. From his original response, I thought I understood why, but now I'm not so sure. Can you guys bear with me here, and provide more information?

Unfortunatly I don't know the technical aspects of it, but the docs say it has to do with apartment threading model. My ASSumption is that, even though there are multiple threads, there is only ONE method/chanel to present UI in a Win32 machine, so, if two threads tried to present UI it would crash itself.

Of course, I would even recommend that an .EXE server doesn't have a UI either...

I would say, Randy Brown is the guy to email if you want the technical resons why... I just accept it, and go with the flow.
