Thanks to everybody who responded to my post. This is all too complicated for what I needed to do. I wanted to create a class that could be used by many different applications on different machine without the need of running any configuration on each machine.

I had 3 choices for designing my class:
1) Create a VCX: have to recompile every application after each change to the class
2) Create a DLL (COM): have to register it on every machine and need to distribute it to every machine after each change to the class
3) Create a EXE (DCOM): the steps to make this work seems to be too complicated. I don't know if the server on which I wanted to install it has DCOM95 installed. It does pose a problem if I need to reboot the server after configuring it correcly, this server is in use from 7:00 AM to 3:00 AM. Unless you want to wake up at 4:30 AM...

Thanks again
