not knowing a lot about this but what I have played about with....but are VB and DB useing the same port numbers?, DB likes to be "different" did you do a "perform checklist for net connections" and then "set net connection" ?, if you mean the perform checklist for net connections comes up with nothing then I have no idea, if you find a connection on the checklist then you need to scan that connection with "perform checklist for net sessions" to find the correct net session and then "perform checklist for net players" to find the net game players, so you do
perform checklist for net connections
<find the connection you want..the index is the connection no>
set net connection <using the connection no>
perform checklist for net sessions
<read names to find the session you want>
join net game <joins you to a net game session>
perform checklist for net players <find the id`s and local/host player>
if you do all that it should work (IIRC), but sending net data is full of weirdness, mostly due to my program errors (since I am not used to coding netgames...I think single player) and I only wrote a few demos to try it out when I was testing DB, cheers.
