an activex dll can be distributed [to different machines] as a standalone object libraries containing classes, while classes in itself cannot be distributed to run as object library but can only be compiled into other projects or activex dlls

Besides, activex dlls are compatible across languages etc, provided they got gud n standard interfaces.
As in, i cud create an activex dll in c++ and use it in vb as well.

Jus see the advantages of doing some things ezier in one language n using em across.

Activex dll's help to enforce ones intellectual prop stuff, i.e if u are working in a company, u mite want to do so. Sending out class modules doesnt get u anythin except technical satisfaction.

A big advantage is you remove portions of logic in a program into separate installable components.  For example, say you put all your math computations into an ActiveX DLL.  Assume you later find a bug in one of your computations.  If this was a large program, you would have to recompile and send out this huge executable to all of your clients to get them updated.  However, if resides within a DLL, you simply recompile the DLL, and distribute that and your clients will be updated.
