ActiveQt registers the server executable for out-of-process servers with
the "-activex" parameter, i.e.
"c:\qt\4.2.3\examples\activeqt\simple\simpleax.exe -activex". If the
executable is launched by COM, then it will be started with the -activex
parameter, and will fire up the COM server before calling main() (which by
default just starts the event loop). QAxFactory::isServer will return true
in your control code.
If the executable is started by the user (ie. without -activex), then
main() will be called without the server started; the default main()
function will still start the server, but if you write your own then you
can decide if you want to start the server, or just start a regular
application, or do both.
