Hi Henrik,

You haven't provided enough info (for me, at least)...

> I get the following access error:

At which exact line do you get the Access violation? And just to be sure -
is HardwareInterface.exe your server, or your client?

> Is it impossible to use "new" in the interface proxy class.

I don't know what you mean by "interface proxy class" - you mean the
implementation of your interface? If so, then sure it's possible, unless you
attempt to return a pointer to that memory to clients.

Which constructor? CMyInterface::CMyInterface()? If CMyInterface is the
implementation of a COM interface, and you create an instance over DCOM, and
call several methods on said interface, then the answer is no. Your
implementation class is not re-created for every call.
