Atos

I've tried adding the sample config from here:

This has no effect when applied here:

When RTI DDS gets upset (Windows) it seems to stick up a black dialog with error information.

I've reworked an app to use minimum number of domain participants (the subject of another post) which seem to be working except when I close the app it throws a black-dialog-of-doom just long enough to flash but not see what it's saying. 

I've written an entirely functional first app which creates four different topics, various readers/writers all wrapped as objects, all operating independently.

Superficially it's working well - but now I'm trying to work out how I should have written it!

Currently, each reader or writer has it's own domain participant, a topic gets created for each contributor/subscriber to the topic - separately for each reader/writer...it works, but my research says likely to come crashing down in a big heap the bigger the system gets.
