Hello,
Ok. I found the technique, but it is extremely unreliable. Here is what I am using: Private Sub IQFeed_SystemMessage(ByVal eventSender As System.Object, ByVal e As AxIQFEEDYLib._DIQFeedYEvents_SystemMessageEvent) Handles IQFeed.SystemMessage Debug.WriteLine("SystemMessage" + e.strSystemData) Select Case True Case InStr(e.strSystemData, "S,SERVER CONNECTED") ServerPanel1.state = ServerPanel.ServerPanelStates.connectedToIQFeed End Select End Sub Out of more than 10 launches, it worked twice. take care, lee |

You should certainly be able to use the S,SERVER CONNECTED system message (and the paired S,SERVER DISCONNECTED system message) to determine if the feed is connected or not.
When you say that it only worked 2 out of 10 launches. Are you saying that in the other 8 launches, that this message was never delivered to your app? |
