First i want to thank Quek about the great answer !!!
Second I'm having a problem that i want to discover.
I want to know how Probe option work and could i take information from the probe about a net .
I need the paths and vias(db) (and put inside a list) that being highlight doring the probe option.
Sorry to be a bit picky - it just helps anyone searching to have clear distinction in the threads - plus there's a mechanism to highlight unanswered threads, which won't work if you continue a very old thread. So you're more likely to get an answer (because your unanswered append to an old thread might get accidentally forgotten).
No problem though - I don't want to get too fussy about this!
