I'm using the 4.8 beta with .net, and it appears that, for a single query, the callback for both ReqSymbolByNAICS and ReqSymbolBySIC for DTNIQFeedCOMLib.SystemInfoClass is called many times (one line of the result per call) instead of just once (multiple lines in a single call). Is this intentional? How are we meant to know when all the results are in?

traps, those requests are in the ISymbolLookup3 interface (not ISystemInfo).

The results for symbol lookup being sent one at a time is intentional. You will receive an endmsg when all results are complete.
