I never thought COM offered anything better than properly designed dlls

It actually did.

I do indeed, and shows I shouldn't rush my answers when typing. I was going for IUnkown originally then threw in QueryInterface. This is the problem when posting from your phone.

Is your phone an 'i' prefixed one? Nowadays they prefix everything with 'i'. See for yourself.[^]

I seem to recall Don Box sitting on stage at Tech-Ed in Barcelona some years ago writing .Net code and saying something along the lines of "What the hell was I thinking for all those years"

Yeah, it stopped idiot programers making a mess of the system I suppose.

Nope, it is all about binary components re-using (as the name suggests).

COM is dead? But ask "where?". COM is dead in user applications. There used to be tons of classic Asp, VB6.0 & even VC 6++ solutions that made extensive use of COM, DCOM, ActiveX etc.In these places, for example COM is literally dead. If a clients requests for a solution for their business, the application developers would no more need to look out for COM. So much has evolved in the managed world. Microsoft took pain to carry all those complex COM on their shoulders. Giving you the option to develop in much simpler tools. For example, DCOM is replaced by remoting in Dotnet, WCF & so many new frameworks give you much cleaner interface for your distributed apps. If you look at COM generated marshalling code, it'd look like it's done by a drunk php coder ;P. But COM is still there in every other places. For example, UMDF (driver framework, uses COM). So the idea is this, if you really need COM, it's there.

I was always told it was a way to avoid DLL hell. Of course if people renamed funcs when they changed the parameters in dlls we wouldnt have had that problem. I have used COM, never found it any better that a dll, and the installation is a PITA.

That's a really naive point.

:thumbsup: Well said :)

Computers have been intelligent for a long time now. It just so happens that the program writers are about as effective as a room full of monkeys trying to crank out a copy of Hamlet.

It will wise at any time. At least to have some insight: COM is fashinating.
