You can call them from another thread (I have done so in my NM3
application)
but you must follow the rules of COM threading. You must marshal
the interface
in the main thread (that which is associated with main STA) and send
the
stream (IStream) along as a parameter on the CreateThread() call (or
_beginthreadex()).
The thread must then create and initialize its own single-threaded
apartment
and unmarshal the interface from the argument stream. It is then
free to call
any method on the marshaled interface.
If you are interested, start with the Win32 calls:
CoMarshalInterThreadInterfaceInStream(...)
CoGetInterfaceAndReleaseStream(...)
You can also create your application in a multi-threaded apartment,
which would not
require you do the marshaling (but would require a lot of other work
on your part).
