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.
