"I would just like to say that IQFeed version 4 is running very well and I am very happy with its performance. I would also like to extend a big thanks for the fast and efficient help that I always receive. My questions and concerns are always addressed promptly. Way to go!" - Comment from Josh in CO.

"My broker in Davenport suggested I give you a try as he uses your service and says its the best." - Comment from Bill via RT Chat

"IQ feed works very well, does not have all of the normal interruptions I have grown used to on *******" - Comment from Mark

"I am a hedge fund manager here. It’s funny, I have a Bloomberg terminal and a Bridge feed, but I still like having my DTN feed!" - Comment from Feras

"I use IQ Feed, Great stuff as far as data analysis information, storage and retrieval is concerned." - Comment from Public Forum

"This is an excellent value, the system is generous (allowing for 500 stocks) and stable (and really is tick-by-tick), and the support is fantastic." - Comment from Shirin via Email

"I have been using IQFeed now for a few years in MultiCharts and I have zero complaints. Very, very rare to have any data hiccups or anything at all go wrong." - Comment from Public Forum

"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob

"You are either overstaffed or people just don't have problems with your feed because customer support always answers the phone quickly." - Comment from Jay via Email

"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam

Author	Topic: How gracefully reconnect to DTN server from VB code (6 messages, Page 1 of 1)
newoleg1 -Interested User- Posts: 11 Joined: Oct 29, 2007	Posted: Aug 27, 2008 08:37 PM Msg. 1 of 6 For example I connected using IQFeedY1.RegisterClientApp(ProdID, ProdKey, ProdVersion) and for some reason I do not get quote from DTN. So I want to shot down IQConnect and restart it again from VB code. Sometimes ago I tried using IQFeedY1.RemoveClientApp() and then call IQFeedY1.RegisterClientApp(ProdID, ProdKey, ProdVersion) again but it seems does not work. Thanks Oleg

Your Feed Stats screen or the S,STATS message will identify how many are currently connected.

DTN_Steve_S -DTN Guru- Posts: 2093 Joined: Nov 21, 2005	Posted: Aug 28, 2008 10:38 AM Msg. 4 of 6 Since you are using the ActiveX control (IQFeedY), and it manages the socket connection for you, you will have to destroy your instance of the control and create a new one. Depending upon your setup, this might require you to destroy the form that you have the control on. Once you have a new instance of the control, you can call RegisterClientApp to reconnect it.
