a COM dCOM question

This may sound stupid but can someone give me a good explanation.

I have been designing and using Active X Dll's and Ocx's for a while now. How am I using COM when i use these.

Can someone give me a real time example of using DCOM and how you would instance Dll's etc on a differnt machine.

I understands what a 3 tier architecture is

Thanks

Hi there, a simple example:
Yo build your Dll and install it in MTS/COM+, the if you want to call it from different remote machines you will need to export the application. Now when you call the Dll it will use DCOM to communicate.

DCOM object are only Out-process because they will live in a separate memory allocation (Two different machines) so you cannot create a dll and use it across machines.

Hope this goves you an idea.
