"Just a thank you for the very helpful and prompt assistance and services. You provided me with noticeably superior service in my setup compared to a couple of other options I had looked at." - Comment from John

"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum

"I just wanted to let you know how fast and easy I found it to integrate IQFeed into our existing Java code using your JNI client. In my experience, such things almost never go so smoothly - great job!" - Comment from Nate

"As a past ******* customer(and not a happy one), IQ Feed by DTN is a much better and cheaper product with great customer support. I have had no problems at all since switching over." - Comment from Public Forum

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.

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.
