have a question for iqfeed client developer: how many history request through socket 9100 can iqfeed client handle before it crash? when test,what language do you use? becos I am too frustrate by using c# to connect to iqfeed with socket. (stream data is very stable,but the history socket not stable) need some suggestion,do I need switch to com object? or it is my code's problem? or wait the next version? Thanks a lot for help

yes,I using IQLink Launcher to launcher the iqconnect and iqlink to get news story in c# I using tcpclient connect to 9100, send command "NN:(ID):(Type):(Date);" to 9100, after that,i close the networkstream and tcpclient. then IQLink launcher crash, but iqlink and iqconnect still ok,just can not connect to 9100 any more. the other situation crash IQLauncher is When I open the connection to port 9100 when debug,before close tcpclient,I stop my program. SO Now I just leave the networkstream open,only close the tcpclient after I done, it is ok. Thanks for reply

every time after i request a history data,i open 9100,if i close the socket ,it will cause IQLauncher crash,so i just leave it. when i using netstat,i saw huge list of 5009,9100 was in status "ESTABLISH" I thought IQFeed never close thoese socket?
