Hello,
I'm wondering how one is supposed to use the PnP event that is available from an ImaqDX session. It offers 'Camera attached' and 'Camera Detached' events which sounds very useful to me.
I'm coding a multi-camera monitoring application using GigE interface. It should be possible plug cameras in or out during the session without much hassle and this facility sounds like it could do the job.
But I don't understand how to code it with LV2011, ImaqDX is also the newest. Connecting an empty DX session, or one where camera is named but not connected, to 'Register for events' gives the error 'Invalid session'. So to even start listening to these events, I need to have a camera connected. In this case a 'attached' event seems to be of no use, and I don't receive any disconnect events either.
To me it seems that there should be a 'generic' camera attachment event, where the event provides the DX session reference. Is there anything like that available?
Thanks for your response,
JL
